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, utilizing only a single, high-quality receiver.This goal is accomplished by combining two processing philosophies: point positioning, which makes use of precise GPS constellation ephemeris and clock offset information to estimate a single receiver’s state; and carrier-phase – filtered pseudorange processing, in which pseudorange-based positioning is supplemented with carrier-based position-change information. Results derived with the developed software indicate that neardecimeter- level positioning accuracy is attainable for a variety of platforms, ranging from static, terrestrial reference stations, to aircraft, to satellites. A number of modeling improvements can be applied to the existing software, and testing in the real-time environment is planned.
