Development of a Low-Cost GPS-Based Time-Space-Positioning Information (TSPI) System

Benge D. Scott

Abstract:	The Navigation and Data Link Section of NAWCWPNS China Lake was tasked to develop a low cost Time-Space- Position-Information (TSPI) system for airborne vehicles based on GPS technology. The portable system developed provides vehicle positioning information in geographic areas not supported by instrumented ranges while maintaining compatibility with existing telemetry range assets. The system reports TSPI data via an RF down link in a standard PCM telemetry frame format. An onboard data logger is provided for telemetry backup while an interface for sampling analog input signals and incorporating the data into the telemetered data is also provided. Development cost was minimized by utilizing off-the-shelf industrial components modified slightly to tolerate the environmental conditions. This system provides the Navy with an inexpensive but highly adaptable and capable TSPI system.
