Abstract:	Differential carrier-phase positioning overcomes some of the operational limitations of carrier-phase kinematic positioning in a 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. The differential carrier-phase method enables several-centimeter positioning at a high rate dependent on the remote receiver observation rate, but relatively independent of the data link transmission rate. This paper discusses the design, successful implementation, and test results of a real-time differential carrier-phase system.
