TriG: Next Generation Scalable Spaceborne GNSS Receiver
TriG is the next generation NASA scalable space GNSS Science Receiver. It will track all GNSS and additional signals (i.e. GPS, GLONASS, Galileo, Compass and Doris). Scalable 3U architecture and fully software and firmware recofigurable, enabling optimization to meet specific mission requirements. TriG GNSS EM is currently undergoing testing and is expected to complete full performance testing later this year.

Topex/Poseidon Orbit Determination Using Global Positioning Satellites in Anti-Spoofing Mode
Results of operational orbit determination for the TOPEX/POSEIDON (T/P) mission using Global Positioning Satellites (GPS) during Anti-Spoofing (AS) activities are presented in this paper. Sub-decimeter radial orbit comparisons have been made with solutions determined from LASER and DORIS tracking.

Design and predicted performance of the GPS demonstration receiver for the NASA Topex satellite
NASA's Ocean Topography Experiment (Topex) satellite will perform topographic ocean mapping. Topex will carry an experimental tracking system based on the use of GPS (Global Positioning System). An onboard GPS Demonstration Receiver (GPSDR) will be used with a network of up to ten receivers at precisely known ground sites. Following a brief overview of the Topex mission and its derived accuracy requirements, the authors describe the design of the GPSDR. The major hardware and software components are reviewed and discussed. Projected receiver tracking and navigation performance measures are presented and discussed.
