AN INTEGRATED GPS TRACKING AND TELEMETRY SYSTEM FOR RANGE APPLICATIONS

Abstract

This paper describes a highly integrated and low cost GPS Translator/Telemetry system for use on missile platforms – the Digital GPS Translator (DGT), a component part of the Translated GPS Range System (TGRS). The DGT provides translated GPS tracking capability combined with transmission of telemetry at rates of up to 10 Mbps with optional encoding and/or encryption. This integrated approach to GPS tracking and telemetry results in a significant reduction in hardware size and cost compared to a segregated approach. The TGRS includes a ground-processing unit that provides real time processing of both the GPS and telemetry portions of the DGT transmission.
