High-Precision Platform Positioning with a Single GPS Receiver

Sunil B. Bisnath and Richard B. Langley

Abstract:	The goal of the research described in this paper is the design of a GPS data processing technique capable of producing high-precision positioning results, regardless of platform dynamics, utilising only a single, high-quality receiver. This is accomplished by combining two processing philosophies: point positioning- making use of precise GPS constellation ephemeris and clock offset information to estimation a single receiver's state; and carrier-phase-filtered, pseudorange processing - supplementing pseudorange-based positioning with carrier-based position-change information. Results determined via developed software, indicate that near decimetre-level positioning accuracy is attainable for a variety of platforms ranging from static, terrestrial reference stations, to aircraft, to satellites. A number of modelling improvements can be applied to the existing software, and testing in the real-time environment is planned.
