PURPOSE OF EQUIPMENT. The Iridium NEXT system (which is comprised of the IRT-4000, ICM-4000 and HGA-4000) (see Figure 1-1) provides Cabin Voice and Data communication through the Iridium network of 66 Low-Earth Orbit cross-linked satellites that provide service anywhere on the planet in all weather conditions without compromise. Iridium satellites orbit at an altitude of 785 km (4485 miles), circling the earth once every 100 minutes. Each satellite is cross-linked to four other satellites; two satellites in the same orbital plane and two in an adjacent plane. NOTE Until regulatory guidance on single-channel SATCOM with mixed Aircraft Control Domain (ACD) and Passenger Information & Entertainment Services Domain (PIESD) is available, the IRT-4000 shall only provide cabin voice and data services. At present the Federal Aviation Administration (FAA) requires that systems which provide both ACD/Airline Information Services Domain (AISD) and PIESD connectivity have the PIESD in an isolated partition separate from the ACD/AISD services. TSO C159D and later further states that the loss or failure of this isolation between domains is a MAJOR failure condition. 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page.

Iridium Cabin SATCOM System, Interfaces 1.4.2. Iridium Cabin SATCOM Function. The IRT-4000 contains a single modem (Iridium Certus Broadband Core Transceiver (BCX)). The BCX is the core digital and Radio Frequency (RF) module of the Iridium Certus satellite communications service. Integrated with Broadband Application Electronics (BAE), Broadband Active Antenna (BAA), and appropriate ampliers, the BCX (uniquely designed to support Iridium Certus L-Band services 1616 to 1626 MHz) provides multiple data speed rates, three simultaneous high-quality voice calls, back-
ground IP data. The IRT-4000 is connected to an HGA or high gain antenna that provides data rates of 352/704 up/down. The IRT-4000 or Satellite Data Unit (SDU) follows the ARINC-771 wiring denition. The Cabin solution IRT-4400 system only connects to the cabin domain or PIESD. The primary function of the IRT-4000 is to provide voice and data communications. A graphical web interface is used for data load and maintenance procedures involving the 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page. GENERAL INFORMATION Page 1-3 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM IRT-4000. Refer to Paragraph 1.5 for additional information on the Aircraft Service Domains. The IRT-4400 provides service to the PIES Domain, while the IRT-4100 through IRT-4300 is capable of supporting two aircraft domains, the ACD and the AISD. The Cabin solution IRT-4000 uses the HGA antenna that provides data rate of 352/704 but only connects to the cabin domain or PIESD. The PIESD domain is serviced via two Ethernet ports (ETH2, ETH12 per A771-1) These interfaces provide 3 channels of Voice usingSession Initiation Protocol (SIP), Voice over Internet Protocol (VoIP), and IP data services simultaneously. The IRT-4000 has ARINC-429 inputs for GNSS, discrete inputs for weight on wheels and data load enable. GNSS position data is only used in log les while the ground speed and Weight On Wheels (WOW) discrete are used to limit transmit power while the aircraft is on the ground (this is to protect nearby GLONASS receivers). 1.4.3. Components. The IRT-4400 system is comprised of the following hardware components:
IRT-4000 (P/N: 822-3585-400) (Also referred to as the Satellite Data Unit (SDU)) ICM-4000 (P/N: 822-3584-400) (Also referred to as the SDU Conguration Module (SCM)) HGA (P/N: 822-3586-400). NOTE The following are not provided with the IRT-4400 ship set:

IRT-4000 Reference View 1.4.3.2. The ICM-4000 (also referred to as the SDU Conguration Module (SCM)) is a small electronics box with anges for mounting to a structural surface, as well as a ground stud to attach the ICM-4000 chassis to the aircraft chassis for lightning protec-
tion. The ICM-4000 has one I/O port and an access panel on the left side to remove/install the Iridium CERTUS Subscriber Identity Module (SIM) card as shown in ICM-4000 Reference View Figure 1-4. After power-up, the ICM-4000 is detected by the IRT-4000. The IRT-4400 system reads the conguration settings from the ICM-
4000 and completes startup using those settings for operational use. The ICM-4000 stores and provides the system conguration and directory information and the SIM used by the Iridium network. Primary ICM-4000 software functionality encompasses the following:

nectivity from ground to air enables Communication, Navigation and Surveillance (CNS) data for Air Trafc Management (ATM), ight information and alerting, and direct Airline Operations Communications (AOC), which can impact aircraft safety and ef-
ciency. The AISD may provide services and connectivity between independent aircraft domains such as avionics, in-ight entertainment, cabin distribution and any connected off-board networks. The AISD provides a security perimeter, incorporating network routing and security functions and services between the AISD and less critical domains PIESD and any connected wireless networks. The PIESD is characterized by the need to provide passenger entertainment and network services. The PIESD is dened to include more than traditional in-ight entertainment systems; that is, any device or function of a device that provides services to passengers. Figure 1-5.

GENERAL. This chapter provides installation information for the Iridium NEXT System. Procedures must be performed as described below to make sure proper operation and performance. NOTE The information and instructions provided in this chapter are recommendations and do not necessarily correspond with any actual aircraft installation and wiring. This chapter cannot be used in place of a Supplemental Type Certicate (STC) or Type Certicate (TC). 2.2. UNPACKING AND INSPECTING EQUIPMENT. Unpack the equipment carefully and make a careful visual inspection of the unit for possible shipping damage. All claims for damage should be led with the transportation company involved. If claims for damage are to be led, save the original shipping container and materials. If no damage can be detected, replace packing materials in the shipping container and save for future use (for example, storage or reshipment). Perform a visual inspection of the unit and inspect for the following concerns:
1. Any damage or corrosion. 2. All parts are intact and in working order. 3. Connectors for any damage, corrosion and broken or bent pins. 2.3. PRE-INSTALLATION CHECK. Remove all electrical power to the equipment and/or equipment mounts before installing or removing them. Prior to installation of the unit in the aircraft, make sure the system equipment interfacing with the Iridium NEXT System is operating properly and all applicable tests have been performed. Refer to the latest revision of the Component Maintenance Manual (CMM) or Illustrated Parts List (IPL) to perform testing of the unit. In the absence of the CMM/IPL, use the Acceptance Test Procedure for the panel variant used to perform testing of the unit. 2.3.1. Cabling Precautions. The following precautions are to be observed during the preparation of the interconnect wiring cables:
1. Bond and shield all parts of the aircraft electrical system, such as generators and ignition systems. 2. Keep connecting cables away from heavy current carrying circuits, pulse transmitting equipment, and interference sources. 3. Make all external connections to the system equipment through the designated connectors. 4. 5. 6. The required hardware and connector are supplied if specied. Suitable wire should be used in accordance with applicable specications. Leave slack in the cable to allow free movement of equipment, keeping wires from breaking. 2.4. PLANNING. Proper and careful planning prior to installation is essential for reliable performance and easy maintenance. The list that follows is a sample of the points to be considered in planning an installation:

Page 2-1 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM 1. Installation location. Allow for adequate airow for cooling, good bonding to aircraft ground, ease of cable routing, room for single/dual/triple mounting in a location that provides structural rigidity. 2. Installation conguration. 3. Compatibility with other equipment and loading considerations. 2.4.1. Installation Congurations. The complete conguration is dependent on the desired connections to ancillary equipment. 2.4.2. Strapping Options. There are no strapping requirements for the Iridium NEXT System. 2.4.3. Input Power. All power required by the Iridium NEXT System is provided by the aircraft in which the system is installed. The Iridium NEXT System requires an input of +28 V dc at 125.0 watts (max) of power for normal operation. NOTE The 125.0 watts is required due to the High Gain Antenna (HGA) being powered through the IRT-4000 per AR-
INC 771-1 (Iridium Low-Earth Orbiting Aviation Satellite Communication (SATCOM) System). 2.4.4. Cooling Considerations. The IRT-4000 is designed with downward-owing draw-through air coolant in accordance with ARINC 600. There are no internal cooling fans, and no ltration is required (see Figure 2-1). The IRT-4000 can be operated either passively cooled or with forced cooling air. When using passive cooling the operating high temperature limit is reduced to +55 C. The mounting tray must not obstruct the cooling air vents on the bottom of the SDU and sufcient space above and below should be kept allowing convection cooling to take place. 2.5. CABLING INSTRUCTIONS. MAKE SURE THAT THE AIRCRAFT BATTERY MASTER IS TURNED OFF BEFORE INSTALLING ANY OF THE INTERCONNECT CABLING. FAILURE TO DO SO COULD CAUSE ELECTRICAL ARCING THAT MIGHT RESULT IN DAMAGE TO THE EQUIPMENT OR SERIOUS INJURY TO MAINTENANCE PER-
SONNEL. Interconnect cables should be prepared in accordance with the interconnect diagrams which are part of approved Supplemental Type Certicate (STC) data packages. 2.6. INSTALLATION PROCEDURES. This section contains procedures for installing the Iridium NEXT System in the aircraft. Procedures must be performed as described below to make sure of proper operation and performance. 2.6.1. IRT-4000 Installation. See Figure 2-1 and perform the following steps to install the IRT-4000. a. b. Ensure power has been removed from the system.

Subscriber Identity Module Card Installation. NOTE The ICM-4000 Iridium CERTUS Subscriber Identity Module (SIM) card is installed when the unit is shipped. The SIM card is inactive at time of delivery. A Service Provider (SP) must be selected to have the SIM card activated. Perform the following steps to install the SIM card:
a. Ensure the IRT-4400 system power is off. b. Open the access cover on the left side of the ICM-4000. c. Remove the SIM card and then install the replacement SIM card. d. Close the access cover on the ICM. e. Apply power to the IRT-4000 system. 2.6.4. HGA-4000 Location. The HGA-4000 should be mounted on a level horizontal plane, such as on the top centerline of the aircraft fuselage or as close as practical to the centerline. The HGA-4000 antenna is designed to meet performance requirements from 8 to 90 degrees of elevation
(measured from horizon). While positioning the antenna off-centerline could impact low elevation performance, the Iridium con-
stellation of 66 satellites provides visibility to multiple satellites insuring connectivity. Antenna locations must consider the impact an Iridium Certus terminal may have on GNSS receiver operation. The intended output power levels of the Certus antenna requires more than the typical 40 dB of port-to-port isolation when used with most TSO compliant GPS receivers and antennas. Isolation by antenna separation alone may be impractical and require an antenna and/or GPS receiver that is more tolerant of high energy SATCOM signals operating near the L1 GPS band. When multiple SATCOM terminals or L-Band transmitters are installed on the same aircraft, the total output power of all transmitters should also be taken into consideration. Since many MOPS standards exist for both GPS receivers and antennas, the installer should use the tables found below to determine the required Iridium Certus to GPS isolation for the equipment installed, or to be installed. 2.6.4.1. Iridium Certus to GPS Required Isolations The required isolation between the HGA-4000 and the GPS antenna is the greatest of three considerations:
Isolation to ensure that the interference mask of the GPS receiver and antenna combination is not exceeded at Iridium Certus transmit frequencies. Isolation to ensure the P1dB (in) compression point of the GPS antenna is not exceeded. Minimum isolation of 40 dB (5 ft, 1.5m). Using published MOPS values for the various GNSS antenna and receivers, the required separation between antennas is 405 inches
(33.7 ft) to as much as 1050 inches (87.5 ft) for some antenna types. These distances are not practical and are calculated using worst case values. Antenna and receiver manufactures can declare P1dB (EP1dB) and lter performance (EGAP) that exceed published MOPS requirements. The excess performance can then be used to reduce the required distance between antennas. For most GPS and antenna combinations, tables 1 and 2 can be used to determine required separation given the antennas manufactures declared excess performance. For example, for a DO-228 compliant antenna, an antenna manufacture could declare that the P1dB performance of their antenna is 7.5 dB better than MOPS spec and the frequency rejection at 1618MHz is 19 dB better than the applicable MOPS. Using those values, Table 1 would indicate that the minimum separation should be 120 inches. If at the aircraft level it is determined that excess antenna performance has been used to mitigate RF interference for other instal-
lations/modications, the declared excess levels must be reduced by the amounts applied in previous installations before using the provided tables. The installer shall record in the certication documentation that excess performance was used and the levels or excess performance needed for the installation. For amended TCs or STCs this might include current SATCOM and GNSS certi-
cation information to dene the conguration starting point for the modication. The installer should include:
1. A sheet into Aircraft Maintenance Record and/or Aircraft TCDS on GNSS Interference Assessment. 2. Aircraft level conguration of applied or concurrent STCs which might impact GNSS interference, and if possible. 3. Other alterations which might impact GNSS interference. 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page. INSTALLATION\

Antenna Separation Considerations As a general guideline, the Iridium antenna should be mounted on top of the fuselage, as close to the centerline of the aircraft as possible. Exceeding an offset 2 may result in a performance degradation. The antenna should be mounted in a location that would provide at least 8 horizontal view of the horizon and minimizing blockage from the vertical stabilizer or other obstructions. See Figure 2-3.

GENERAL. Whether a cabin phone is needed, or where the default phone will be placed, is at the discretion of the customer prior to installation. Cabin voice is provided via SIP/VoIP. Station interfaces are also compatible with standard Plain Old Telephone System (POTS) telephone handsets containing standard Tip and Ring signals. The 2-Wire phone is a back-up to the VoIP interfaces. These phone handsets are typically Dual Tone Multi-Frequency (DTMF) protocol-based. Standard functional capabilities for a station interface include making outgoing calls, receiving incoming calls, tone generation (e.g., dial tones, busy signals, etc.), off-hook detection, and ring signaling (tones sounded upon incoming calls). Congurable functional capabilities for a station interface include: Making Priority Calls, Microphone (MIC) Audio Adjustment, Ear Audio Adjustment, and Noise Reduction. 3.2. CABIN VOICE. The Iridium Receiver Transmitter NEXT (IRT NX) SATCOM system will provide 2-wire audio circuits for the cabin. Up to three active voice calls between the aircraft to the ground will be supported. Voice functionality will include:
Call Priority Call Routing Call Control. 3.3. MAKING A CALL (POTS PHONES ONLY). The IRT-4000 permits use of both the standard North American Dialing Plan (NADP) and the International (European) Dialing Plan (IDP), as the device automatically converts the dialing scheme to that required by the Iridium communication network. To make an outbound call from a cabin phone, follow the steps below:
1. 2. Pick up the cabin phone and listen for a dial tone. If a dial-tone is heard, start dialing the desired number. A DTMF tone will be emitted for every number pressed. After dialing the number, the system will generate a ring-tone indicating the attempt to connect to the number dialed. 3. Wait for the ring back signal or busy signal, if the extension is already in use. If the line is answered, the call is connected. 4. Hang up the phone when nished. If no dial-tone is heard when the Cabin phone is picked-up, the system is not operational. If a number is mis-dialed, the IRT-4000 will pass reorder tones indicating the user needs to hang up and try the call again. NOTE 3.3.1. Call Tones. The IRT-4000 produces the standard set of telephone tones as described below:
Busy Ring Back Reorder Dial Tone Signal indicating the called number is already engaged. Signal heard after dialing a number but before the called party answers the telephone. Fast busy signal produced when an improper or unauthorized number is dialed. Standard tone heard when picking up the handset of any telephone. 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page. OPERATION Page 3-1 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM 3.3.2. Toll-Free Numbers. The IRT allows the user to dial toll-free numbers with the below listed prexes: 1-800, 1-888, 1-887, 1-866, and 1-877. 3.4. NOTIFICATION OF INCOMING CALL. Upon receiving an incoming call signal, the cabin phone will ring, notifying the answering party of a call. How the call is routed varies upon the location from which the call is placed:
For Station-to-Station calls, the incoming call will ring the selected extension for the cabin handset. For Ground To Air (GTA) calls, incoming calls are routed by priority. Priority 4 calls, designated as Public Correspondence, are the only calls routed directly to the cabin. 3.5. TRANSFERRING A CALL. The IRT-4000 has the capability to transfer calls, if Class of Service (COS) and Station-to-Station COS are enabled via the Owners Requirement Table (ORT) Tool. The method of call transferring is determined by the telephone manufacturer. Refer to the manu-
facturers user guide for instructions on transferring calls with the cabin phone installed on the aircraft. 3.6. RECEIVING CALLS. When a call comes from either the ground to the aircraft or from one aircraft to another, the IRT will ring the default cabin telephone established during installation on the aircraft. To answer the call, simply pick up the handset. If all transceivers are in use, the caller will hear a busy signal. NOTE 3.6.1. Default Telephone. When the IRT-4000 is initially installed on the aircraft, an extension is assigned as the default telephone. The default is always Ext. 11 unless changed during initial conguration or subsequent reconguration. The extension circuits are assigned two-digit numbers to identify the stations. The numbering is as follows:

OPERATION Page 3-6 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM CHAPTER 4 THEORY OF OPERATION 4.1. THEORY OF OPERATION. Chapter 4 - Theory of Operation to be updated for Iridium Certus. NOTE The following paragraphs provide a functional description of the Iridium system. 4.1.1. System Theory. The Iridium satellite network has a constellation of 66 satellites in low-earth orbit, terrestrial gateways and Iridium Subscriber (IS). The satellites are placed in an approximate polar orbit at an altitude of 780 km. There are six polar planes populated with 11 satellites per orbit constituting the 66 satellite constellation. The near polar orbits of the Iridium constellation provide truly real-time and global coverage from pole-to-pole. 4.1.1.1. The Iridium SATCOM system is designed to operate in the band of 1616 to 1626.5 MHz although the exact frequencies used depend on the local regulating authorities and issued licenses in any particular region. Each satellite projects 48 beams on the surface of the earth, which may be viewed as providing coverage cells on the ground similar to terrestrial systems. Each beam is approximately 600 km in diameter. The 66 satellite constellation has the potential to support a total of 3,168 spot beams; however, as the satellite orbits converge at the poles, overlapping beams are shut down. The satellite footprint is ~4,700 km in diameter. Under each footprint, a satellite is power limited to ~1,100 simultaneous circuits. 4.1.1.2. The Iridium network uses a Time Domain Duplex (TDD) method and transmits and receives in an allotted time window within the frame structure. Since the system is TDD, the IS transmit and receive in the same frequency band. The access technology is a Frequency Division Multiple Access/Time Division Multiple Access (FDMA/TDMA) method whereby an IS is assigned a channel composed of a frequency and time slot in any particular beam. Channel assignments may be changed across cell/beam boundaries and is controlled by the satellite. The system will provide an average link margin of 13.1 dB. 4.1.1.3. The Iridium network makes calculations of the geo-location of an IS each time a call is placed. The technique employed to determine the geo-location of an IS is based on measurements of the IS and satellite propagation delay and Doppler frequency shift. These measurements are used to estimate cosines of spherical angles that identify the IS location relative to the satellite by the gateway. 4.1.1.4. The Iridium network can locate an IS to within 10 km only about 78% of the time. The position of the IS in the radial dimension relative to the satellite can almost always be determined to within 10 km with just one measurement. Errors in the azimuth dimension relative to the satellite are largest along the satellite ground path and tend to increase with distance from the satellite. Geo-location errors in the east-west dimension are sometimes more than 100 times greater than in the north-south dimension. 4.1.2. Terrestrial Segment. The Terrestrial Segment is comprised of the System Control Segment and Iridium Gateways that connect into the terrestrial tele-
phone/data network. The System Control Segment is the central management component for the Iridium system. It provides global operational support and control services for the satellite constellation, delivers satellite-tracking data to the Iridium Gateways, and performs the termination control function of messaging services. The primary linkage between the System Control Segment, the satellites, and the gateways is via control feeder links and inter-satellite cross-links throughout the satellite constellation. 4.1.2.1. Gateway stations, also called Ground Earth Stations, provide call processing and control activities such as subscriber val-
idation and access control for all calls placed in a Gateway territory. The Gateway station also provides interconnection between terrestrial Public Switched Telephone Networks (PSTN) and the Iridium System by connecting calls made through the Iridium System to and from the PSTN. Gateways communicate with the space segment via Gateway link antennas on the satellites and ground-based antennas at each terrestrial Gateway facility. Each Gateway includes a subscriber database used in call processing activities such as subscriber validation. Each Gateway also keeps a record of all trafc in its territory, controls all user information pertaining to its registered users, and generates call detail records used in billing. Although there are multiple Gateways, a user is registered to a single Gateway. The satellite constellation provides connectivity between users, from a user to their Gateway, and 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page. THEORY OF OPERATION Page 4-1 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM between Gateways. Within the Iridium network architecture, the satellites are cross-linked allowing IS to IS communication inde-
pendent of the Gateway after the call connection is established. The U.S. government owns and operates a Gateway in Hawaii. 4.1.2.2. The Iridium space segment utilizes a constellation of 66 operational satellites in low-Earth orbit. The satellites are located in six distinct planes (see Figure 4-1) in near-polar orbit at an altitude of approximately 485 miles and circle the Earth approximately once every 100 minutes, travelling at a rate of approximately 16,830 mph. The 11 mission satellites, which are evenly spaced within each plane, perform as nodes in the communication network. The six co-rotating planes are spaced 31.6 degrees apart in longitude
(approximately 2,180 miles at the equator), resulting in a spacing of 22 degrees (approximately 1,518 miles at the equator) between Plane 6 and the counter rotating portion of Plane 1. Satellite positions in adjacent odd and even numbered planes are offset from each other by one-half of the satellite spacing. This constellation ensures that every region on the globe is covered by at least one satellite at all times. There are ten additional satellites functioning as in-orbit spares ready to replace any unserviceable satellite in case of a failure. Figure 4-1. Iridium Satellite Network 4.1.2.3. Each satellite has four cross-link antennas to allow it to communicate with and route trafc to the two satellites that are fore and aft of it in the same orbital plane, as well as neighboring satellites in the adjacent co-rotating orbital planes. These inter-satellite links operate at approximately 23 GHz. See Figure 4-2. 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page. THEORY OF OPERATION Page 4-2 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM Figure 4-2. Iridium Satellite Cross-Link 4.1.3. Space Segment. Each satellite communicates with the Aircraft Earth Station (AES) through tightly focused antenna beams that form a continuous pat-
tern on the earth. An AES is an aircraft including all avionics on board necessary for implementing satellite communications. These beams, known as spot beams, may be viewed as providing coverage cells on the ground similar to terrestrial systems. Under each footprint, a satellite is power limited to approximately 1,100 simultaneous circuits. Each satellite uses three L-band phased-array an-
tennas for the user links (within the 1616-1626.5 MHz band), each contains an array of transmit/receive modules. The phased-array antennas of each satellite create 48 spot beams (each approximately 373 miles in diameter) arranged in the conguration (see Figure 4-3) covering a circular area with a diameter of approximately 2,920 miles. The 66 satellite constellation has the potential to support a total of 3,168 spot beams. A consistent sharing of load among satellites is maintained at high latitudes by selectively deactivating outer-ring spot beams in each satellite. This beam control also results in reduced inter-satellite interference and increased availability in high latitudes due to overlapping coverage. 4.1.3.1. The Iridium system architecture incorporates certain characteristics, such as call hand-off, which allows the Space Seg-
ment communications link with subscriber equipment to be transferred from beam to beam and from satellite to satellite as such satellites move over the area where the subscriber is located. This transfer is transparent to the user, even during real-time commu-
nications. 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page. THEORY OF OPERATION Page 4-3 OCT 28/22 PRELIMINARY ROCKWELL COLLINS, A PART OF COLLINS AEROSPACE INSTALLATION MANUAL IRT-4400 IRIDIUM HIGH-SPEED (CABIN) SATCOM SYSTEM Figure 4-3. Spot Beams 4.1.4. Hand Off. The spot beams move rapidly with respect to ISs and other satellites. Hand off is the process of automatically transferring a call in progress from one beam to another (or sometimes within a beam) to avoid adverse effects of either user or satellite movement. This is required in three situations. First, an IS must be handed off between satellites as they move relative to the IS (Inter-satellite). Second, an IS must be handed off between beams on a satellite as beam patterns move relative to the IS (Intra- satellite). Last, an IS must be handed off to another channel within a beam for frequency management and to reduce interference (Intra-beam). Although the Iridium system may force a hand off, hand off processing is primarily IS initiated. As a satellite moves away (for example, moves over the horizon) and a new satellite approaches (for example, comes into view over the horizon), an IS must transfer from the current satellite (the losing satellite) to the new satellite (the gaining satellite). This Inter-satellite hand off, on the average, occurs approximately every 5 minutes during a telephone call. It may be initiated as frequently as 5 seconds or as long as 10 minutes, depending on link geometry. 4.1.4.1. As satellites move from the equator to a pole, the actual distance between adjacent satellites decreases to a few kilometers and then increases to several thousand kilometers as the satellites again approach the equator. To avoid radio interference, beams near the edges of a satellite coverage eld are turned off as the satellite approaches a pole and then turned on again as it approaches the equator. Additionally, the same radio channels are never available in adjacent beams on a satellite or between nearby satellites. Thus, as the satellite and its beams pass by, an IS must frequently transition to a new beam. This Intra-satellite hand off occurs approximately every 50 seconds during a call. 4.1.4.2. As the inter-satellite geometry changes, radio channels must be reallocated among the beams to avoid interference. This process can cause an IS to be handed off to a different channel in the same beam. This is called Intra-beam hand off. An IS can also request an Intra-beam hand off to reduce interference. If the Iridium system detects an allocation change coming up where it will not have enough channels to support the number of current users, the satellite will ask for volunteers to hand off into other beams so calls will not have to be dropped when the resource change takes place. Hand offs made under these conditions are called Volunteer hand offs. Volunteer hand offs may result in one of two situations requiring hand off, namely Inter-satellite or Intra-satellite, but are initiated by the IS (at the request of the Iridium system) rather than by the Iridium system itself. These hand offs are handled automatically and are transparent to the user. 5230834153 US Export Classication: 7E994 COLLINS AEROSPACE PROPRIETARY Subject to the restriction on the cover page.

GENERAL. This chapter provides ight line maintenance instructions for an IRT-4400 system. 5.2. SOFTWARE COMPONENTS. No software component installations are required. The IRT-4000 and ICM-4000 have default software and conguration pre-loaded. Additionally, User ORT and Secure ORT, which are capable of modication, are loadable via PDL or On-Board Networking system. Refer to the IRT-4000 Iridium NEXT System ORT Conguration User's Guide 523-0833711 for additional information. 5.3. ORT CONFIGURATION FILES. The conguration le for User ORT and Secure ORT settings is created by using the IRT-4000 Iridium NEXT SATCOM System ORT Conguration User Guide (UG) . Within the UG is the User Manual for the Owner Requirements Table (ORT) Tool and Directory Editor (hereafter referred to as the ORT Tool). This section details how to install and use the ORT Tool to create phone directories, and modify and upload conguration settings to the IRT-4X00. 5.3.1. The IRT-4000 Conguration Files. The conguration le contains the IRT-4000 unit default conguration parameters. During normal operations, the system reads the product conguration from the ICM when the ICM is detected by the system during system power-up. If the ICM is not detected, or if the product conguration data stored in the ICM is missing or corrupted, the built-in product conguration data will be used instead. 5.4. ORT PARAMETERS. ORT parameters are loaded to the IRT-4000/ICM-4000 via the ARINC 615 Ethernet connection as illustrated in Figure 1-2 IRT-4000 System Interfaces. The ORT Tool may be run on any personal computer that meets the necessary requirements. NOTE An example ATS phone directory le is included with the ORT Tool.

(ICM) Note 3: Fluid Susceptibility will include the following uids tested through spray test method only. In accordance with DO-160G [28] section 11.4.1, it is planned to combine the uids into the 6 test groups as detailed below. Cleaning Solvents (Isopropyl Alcohol and Denatured Alcohol) Disinfectants (Calla 1452 Zip Chem) Extinguishing Agents (Halon 1211) Insecticide One (Pyrethroid Pesticide) Insecticide Two (Callington One Shot) Heat Transfer Fluids (Galden HT 135 from Solvay) Smoke Generator Fluids (Glycerin, CAS# 000056-81-5 [Corona Colt IV smoke generator]; and White Mineral Oil USP [Corona Aviator smoke generator). It is planned on claiming compliance to Halon 1211 by analysis with the following justication: it is assumed that the chemical Halon 1211 (CF2ClBr) is used on the subject aircraft. Use of this product for purposes other than actual re ghting is banned in the US by the Environmental Protection Agency (EPA), due to its harmful reaction with the ozone layer. Thus, it was determined that the unit could not be tested using the Halon 1211. In lieu of being able to perform actual physical testing utilizing Halon 1211, analysis was performed. Review of the Material Safety Data Sheet (MSDS) for this chemical shows that the only materials with which this chemical is incompatible are active metals, such as powdered magnesium. No materials of this kind are present in the IRT-4000 and ICM-4000. Based on this analysis, the IRT-4000 and ICM-4000 are considered to be compliant with the Halon 1211 uids susceptibility requirement. IRT can be installed either with forced air cooling conguration, or passive cooling conguration. The hardware conguration of the IRT is the same in either aircraft cooling conguration. Note 4: This test is only performed on the cockpit conguration only. There are no differences in the performance of the unit. The EUT operates the same with the same kind of circuitry regardless of the cable harness that are attached. The Ethernets may differ but there are no differences in the circuit cards for a cockpit unit vs cabin unit. Note 5: At temperatures below -40C, the IRT-4000 and ICM-4000 will not function. Power may be applied to the IRT-4000 at temperatures below -40C and the IRT-4000 power supply will be energized at -55C (F2 Operating Low Temperature). The IRT-4000 power supply will keep the rest of the IRT-4000/ICM-4000 off. Once the IRT-4000 internal temperature reaches
-40C, and power is already applied, the IRT-4000/ICM-4000 will automatically turn on and function. TEST CONDITIONS ENVIRONMENT NOTES CATEGORY Table A-2. HGA-4000 DO-160G Testing Categories Bonding Temperature Altitude Decompression Overpressure 5230834153

age, then measured across the center con-
ductor pin of 50 load, is to be <300V. This requirement is based on level 3 WF4 pin injection lightning levels (section 22 DO-160). A TNC coax breakout cable will connect the antenna to the 50 load. The induced current on the center pin of the coax will be determined by calcula-
tion. There is no requirement to measure the bulk induced current. The current of each waveform component is to be recorded. Tested in two congurations:
