The NAVSTAR Global Positioning System GPS is a tool which will support military needs for positioning, navigation and precise timing. The U.S. Army Topographic Engineering Center TEC is studying tactical applications of GPS to Army system orientation requirements. The work is being sponsored by the Army Space Technology and Research Office ASTRO. Three brassboard Azimuth Determining System ADS were built under contracts to Adroit, Magnovox and Texas Instruments. All three contractors used the princples of microwave interferometry to determine azimuth. The ADS were successfully demonstrated at the U.S. Army Field Artillery School, Fort Sill, OK in Sep 90. The demonstation proved the concept of using GPS and a short 1 meter baseline to determine azimuth. The accuracy achieved by the brassboard ADS is 5 - 8 mils 6400 mils 360 degrees.
