GPS (Global Positioning System) Data Link for Test and Training

摘要

The Global Positioning System (GPS) is an excellent potential source of time-space-position information (TSPI) for test and training ranges, since this information is available world-wide and can be used by both air and surface players. However, in contrast to ground-based multilateration systems, GPS-derived TSPI is obtained on the player; hence a means of conveying these data to the range central processor must be provided. In this report, the feasibility of using existing data communications systems to report GPS-derived player position, velocity, and time data, with and without additional player event data, was examined. Data requirements for representative range systems were estimated and matched with the capabilities of representative data links. It was concluded that telemetry and the Joint Tactical Information Distribution Systems (JTIDS) are the most viable link alternatives to convey the GPS-derived data to the range central processor.
