Such modifications or changes could void the users authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. RF exposure:

The device has been evaluated to meet general RF exposure requirement, The device can be used in portable exposure condition without restriction. Federal Communication Commission (FCC) Radiation Exposure Statement Power is so low that no RF exposure calculation is needed. NextNav LLC Confidential and Proprietary Page 4 of 26 TerraPoiNT Portable Tracker (TPT) User Guide Version No: 0.8 2 Scope This Receiver User Guide describes all electrical, mechanical, operational and support aspects of TerraPoiNT Portable Tracker (TPT) MBS receiver. The TPT is very small and low power that supports single chip version of NextNavs MBS Receiver Technology along with GPS Receiver and multitude of sensors. This manual reflects the latest iteration of the TPT with the 2021 hardware and software updates. NextNav LLC Confidential and Proprietary Page 5 of 26 TerraPoiNT Portable Tracker (TPT) User Guide Version No: 0.8 3 Introduction Metropolitan Beacon System (MBS) is terrestrial location system designed to supplement GPS in areas where GPS signals are degraded or denied, such as indoors or in urban canyons. The terrestriallylocated beacon transmitters radiate a highly synchronized, spreadspectrum signal that is similar in many respects to the L1 C/A signal, and enables appropriatelyequipped receivers to trilaterate their position. In addition to traditional almanac information, MBS encodes barometric correction information to enable receivers that have a barometric pressure sensor to determine their altitude with very high accuracy. Additional information about the MBS signals can be found in the MBS Interface Control Document (ICD) [1]. NextNav MBS beacons operate on Part 90 MLMS spectrum licenses that cover 919.75MHz 927.75MHz, with permitted ERP up to 30W. The system currently supports a 10Hz location update rate, with position computed on the receiver with no need for external information. Like GPS, assisted modes of operation are supported. A highlevel system architecture of MBS is shown in figure below. NextNav LLC Confidential and Proprietary Page 6 of 26 TerraPoiNT Portable Tracker (TPT) User Guide Version No: 0.8 The block diagram of the TPT class receivers shown below. The TPT receiver system comprises of a measurement engine (ME) block, a compute module block, gps receiver and different sensors. The measurement engine block performs the acquisition and tracking of MBS beacon signals. The compute module receives the ME data and computes the ranges and trilateration to produce location fixes at 10Hz rate. The receiver is designed to interact and deliver location fixes to a host platform (Smart Phone) via Bluetooth.
