High-Rate Precise Real-Time Positioning Using Differential Carrier Phase

Dariusz Lapucha, Richard Barker, and Ziwen Liu

Abstract:	Differential Carrier Phase positioning overcomes some of the operational limitations of the carrier phase kinematic positioning in the real-time environment. Unlike kinematic positioning, differential carrier phase positioning does not require time-matching of reference and remote station data. The observation time-matching adds the data link delay to the position latency and prevents positioning when the reference data transmission is interrupted. The differential carrier phase algorithm is based on determining and then applying the GPS carrier phase errors instead of direct observation differencing. Differential Carrier Phase method enables several centimeter positioning at a high-rate dependent only on the remote receiver observation rate but independent on the data link transmission rate. This paper discusses the design, successful implementation and test results of the real-time differential carrier phase system developed by John E. Chance and Associates Inc.
