Abstract: The NAVSTAR Global Positioning System (GPS) Program is currently in the first of three phases in the Department of Defense acquisition process. Phase I, Concept Validation, includes building engineering development models of the GPS User Equipment and extensive in-plant and field Developmental Test and Evaluation (DT&E). The overall objectives of Phase I DT&E are to validate the GPS concept, to validate the preferred design, to define system costs, and to demonstrate military value. Field checkout tests are now being conducted at the Army Yuma Proving Ground (YPG), Arizona. The Joint Test Team is managed by the GPS Joint Program Office at the USAF Space and Missiles System Organization. General Dynamics Electronics has had primary responsibility for the test program, especially with User Equipment developed by their subcontractor, Magnavox Advanced Products Division. Texas Instruments and Collins Radio Group will also test their User Equipment later this year. Test operations and data reduction are supported by the Yuma Proving Ground. Host vehicles and crews are provided from several Air Force, Army, Navy, and Defense Mapping Agency units. Phase I field checkout testing has been underway at YPG since March 1977. This paper presents some of the preliminary results from these early field tests.
