Abstract:	The Defense Mapping Agency in conjunction with other government agencies is sponsoring the Development of GPS user equipment which will benefit greatly the Mapping, Charting and Geodesy community. The developments include the first GPS receivers for space applications and GPS receivers for geodetic survery applications. Both projects utilize technical support of the Naval Surface Weapons Center at Dahlgren. The receiver for space applications (GPSPAC) is a joint program funded by DMA and NASA for the development of GPS receiver hardware to fly as part of NASA’s LANDSAT Program. The real-time acquisition of precise ephemeris information will greatly enhance the utility of the imagery acquired by this satellite to the users, and will serve as a pilot experiment for future application of GPS mapping the earth from space. The GPS geodetic receiver development, which will provide prototype receivers for utilization in terrestrial surveying operations, has the potential to significantly enhance the accuracy of point geodetic surveys over the current TRANSIT user hardware capability. The improved accuracy will come with a corresponding reduction in time required to occupy the site and therefore offers operational cost reductions. This program is jointly sponsored by DMA, NASA, USGS and NOAA/NGS. The project engineering work on this program is being carried out at NSWC.
