Dual Baseline Real-Time OTF Kinematic GPS

Dariusz Lapucha and Richard A. Barker

Abstract:	The Dual Baseline Real-Time OTF Kinematic GPS system improves the carrier phase based positioning performance at longer ranges from the reference stations. The system is comprised of two GPS reference stations that transmit satellite measurement data to a user system via a UHF radio telemetry link. Both reference stations transmit data at the same frequency using time division multiplexing. Transmitting data from both reference stations at the same frequency enables using one data link receiver at the user end. The multiplexing process is performed by the base station software that selects which data to send at what time. The system spans between base station epochs using Differential Carrier Phase techniques to provide matching data to perform the closure comparison and to compute the composite kinematic position fix. This paper discusses the design, successful implementation and test results of Dual Baseline Real- Time OTF Kinematic GPS system developed by John E. Chance and Associates, Inc.
