AbstractThe Joint Advance Missile Instrumentation (JAMI) program has developed a Time Space Position Information (TSPI) unit (JTU). The JTU employs a novel use of Global Positioning System (GPS) technology, and inertial measurement units (IMU) to provide a real time trajectory for high dynamic missile systems. The GPS system can function during high g maneuvers that an air-to-air missile might encounter. The IMU is decoupled from the GPS sensor. The IMU data is a secondary navigation source for the JTU and will provide platform attitude. The GPS data and IMU data are sent to the ground in telemetry packet called TSPI Unit Message Structure (TUMS). The TUMS packet is sent to a computer that hosts the JAMI Data Processing (JDP) software, which performs a Kalmam filter on the GPS and IMU data to provide a real time TSPI solution to the range displays. The packetized TUMS data is available in three different output formats: RS-232 serial data, 16-bit parallel and PCM. This paper focuses on how to integrate the JTU into a telemetry system, use it as a standalone system, and provides examples of possible uses.
