Time Space Position Information GPS INS Instrumentation (TSPIGII)
Agency / Branch:
DOD / USAF
The objective of the program is to develop a subminiature instrumentation package utilizing state-of-the-art global position system (GPS) and inertial navigation system (INS) technologies to obtain Time Space Position Information (TSPI). has begun underthis effort. In Phase I of the program, a conceptual design of the hardware was developed. After evaluating commercial of-the-shelf (COTS) hardware for microprocessors and GPS receivers, the TQM850 single board computer (SBC) and the RF8000 GPS receiversrespectively were selected for TSPIGII packaging. A new flat pack IMU was conceived to be included with the SBC and the GPS modules. With these modules, a TSPIGII package was developed that measures (56mmX49mmX25mm). Analysis of the board layouts andinter-module interfaces shows the feasibility of the conceived TSPIGII package. The first iteration of the flat chip inertial devices was completed and devices are being tested in a servo electronics development bread board. A small footprint embeddedLinux was assembled and loaded into TQM850 flash. The Ethernet interface was tested under embedded Linux. In Phase II, the TSPIGII prototype will be built to size using commercial hardware and Waddan?s inertial module. The baseline effort planned forthis phase includes integration of COTS, development of TSPIGII specific system software, development of the flat pack inertial module, Kalman filter design for the tightly coupled GPS/INS and its related software, Bench mark testing, cost modeling etc. Asan optional effort, a flash data storage capability could be added to TSPIGII. Upon completing the development, a TSPIGII prototype unit will be built, tested, and delivered to Edwards AFB for flight testing.
