Abstract : The NAVigation Satellite Timing and Ranging (NAVSTAR) Global Positioning System (GPS) is a tool used to support military and civil needs for positioning, navigation and precise timing. The civil needs for positioning, navigation and precise timing. The U.S. Army Topographic Engineering Center (TEC) is studying tactical and civil applications of GPS to Army missions. For the tactical Army, TEC is investigating GPS for use as a precise surveying tool and for accurate use of azimuth. The integration of GPS with an inertial navigation system is also being studied as a potential improvement for tactical navigation and positioning. For the civil missions of the U.S. Army Corps of Engineers (USACE), TEC is investigating the application of Differential GPS (DGPS) to photogrammetry and hydrographic surveying needs. Code-phase DGPS and Carrier-phase DGPS are being studied with the goal of achieving real-time accuracies of 1-3 meters and .1 meter with the respective approaches.
