58 -- NEW TECHNOLOGY GLOBAL POSITION SYSTEMS (GPS) RECEIVER POC Karen Schutt, 904/882-8601, Ext 5076; Joe Giangrosso, 904/882-8601, Ext 5082 Sources are sought to provide the next generation Global Positioning Receiver (GPS) receiver for the Range Applications Program (RAP). The receiver shall be "All-in-View" C/A and P/Y code capable. The receiver shall be capable of accepting differential corrections locally and providing a desired one sigma RMS position accuracy of 1.0 m in horizontal and 1.0 m in vertical. The receiver must be capable of tightly coupling to an inertial sensor to provide optimal performance in high dynamic environments (up to 10 Gs). It is desired that either a lower quality inertial sensor would be used to provide a one sigma RMS velocity accuracy of 0.1 m/s in horizontal and 0.1 m/s in vertical while a higher quality inertial sensor would be used to provide a one sigma RMS velocity accuracy of 0.005 m/s in horizontal and 0.005 m/s in vertical. The receiver shall be capable of operating in a kinematic mode with a desired one sigma RMS position accuracy of 0.1 m in horizontal and 0.1 m in vertical. If carrier phase is not available the receiver shall gracefully degrade to the next optimum mode of operation and return to kinematic operation when possible. The receiver shall be capable of accepting Wide Area GPS Enhancements (WAGE) if local corrections are not available. The receiver shall perform Receiver Autonomous Integrity Monitoring (RAIM). GPS receiver outputs shall include all raw measurements data (GPS and inertial), full Time-Space-Position Information (TSPI) solution, Kalman filter quality data, and receiver status information. The receiver/inertial unit must fit within an AIS-P4 (AIM-9 type) pod. This equipment is expected to be fielded in 1998. (0076)
