GPS Testing Service

The Global Positioning System (GPS) Test Facility utilizes a variety of tools and facilities, including the GPS instrumentation Suite (GPSIS) and GPS Dynamic Array Test Facility. We have specialized data collection, data reduction and analysis tools that support differentially corrected GPS data, providing position accuracies in the sub-meter range as well as producing truth data during tests.

U.S. Army Electronic Proving Ground (USAEPG) is the sole emergency beacon certification facility in the United States; it is the only certification facility in the Western Hemisphere. Cosmicheskaya Sistyema Poiska Avariynich Sudov – Search and Rescue Satellite Aided Tracking (COSPAS-SARSAT) is an international, humanitarian satellite-based search and rescue system.

Capabilities

GPS Dynamic Array Test Facility is a recently added indoor GPS test range that allows GPS System Performance and Survivability testing under realistic live sky conditions while indoors. A simulated GNSS constellation antenna array used within a large chamber for maximum realism bridging the gap between lab and field testing for GPS/GNSS navigation system evaluation.

GPSIS provides flexibility in testing receivers by providing operational control of dynamic and repeatable scenarios in a low-cost laboratory environment.

80,000 acres of test range, allowing personnel to conduct testing in a variety of real-world environments, including desert, canyon and mountainous terrain, with or without foliage.

Expertise

With 30 years of GPS test experience, USAEPG is well known and respected in the GPS test community.

Our GPS Community Memberships include the GPS Wing’s GPS Test Center of Excellence, Satellite Simulator Control Working, Joint Test Agency Working Group and Army Integrated Product Team.

Value

From the Warfighter/Soldier perspective, the GPS Test Facility is able to test GPS receivers in various operational environments that allows the customer an early look at how well their receivers are functioning. The Dynamic Array’s indoor GNSS constellation will provide significantly more testing opportunity against GPS threats since no need for outdoor over the air frequency request(s) and coordination. The system provides a well controlled signal environment (115dB of isolation minimum) for Developmental & Integration testing. By getting this early look, anomalies can be addressed and fixed prior to fielding, providing the Warfighter with the best possible equipment to accomplish their mission.
