Starting in 1987, Leica Geosystems established a close business relationship with Magnavox's commercial GPS business unit for the design and construction of GPS surveying sensors. This culmi-

nated into Leica Geosystems acquisition of the Magnavox GPS business unit in 1994. With this purchase, the unbroken chain of impressive "firsts" now incorporated the field of satellite navigation and positioning technology. Magnavox was one of the first pioneers in this arena, playing a leading role in the development of GPS and its predecessors. Further acquisition of the Philips Ap Navi-

gator business in 1997 widened Leica Geosystems product palette to an even greater extent. In May 1999, Leica Geosystems entered the GIS/GPS data collection market with the introduction of the Leica Geosystems GS50 GPS sensor and Leica Geosystems GIS DataPRO office software. With the integration of ERDAS and LH Systems in 2001, Leica Geosystems has expanded its product areas to offer four ranges of GIS and mapping solutions - airborne data acquisition, geographic imaging, GPS/GIS, and land information systems. Leica Geosystems' airborne sensors, field data collectors, work-

stations and software help customers create and update GIS databases rapidly, accurately and cost effectively. Leica Geosystems is the first choice for geographic data acquisition systems, 2D and 3D image processing and visualization, and mapping solutions.
