Abstract : Recognizing the need for an accurate, versatile, rapid, simple, and secure method of surveying under all conditions of weather and terrain, the Geodesy, Intelligence and Mapping Research and Development Agency of the U.S. Army Corps of Engineers (GIMRADA) initiated the development of a jeep or helicopter-mountable, self-contained, completely inertial system for the extension of horizontal position, elevation, and azimuth data in engineer and artillery surveys. Under GIMRADA's direction, the Missile and Space Division(formerly Missile and Space Vehicle Department) of the General Electric Company developed, fabricated, tested, and delivered in April 1963 an R and D system which conclusively demonstrated the feasibility of the inertial concept for obtaining accuracies required for Army surveys. Unique error redistribution techniques give this system more accuracy than is obtainable with comparable inertial systems (e.g., navigation). The system accepts and reads out all position data in standard Army Universal Transverse Mercator (UTM) coordinates. Elevation changes are read out directly in meters. All information, except azimuth, is displayed visually and, upon command, is recorded on tape. Azimuth, in military mils, is inserted and read with a built-in precision theodolite. The system also has self-alignment (Gyro-compassing) capability. (Author)
