Single-Epoch Integer Ambiguity Resolution with GPS-GLONASS L1 Data

M. Pratt, B. Burke, and P. Misra

Abstract:	An effitive search technique is presented for resolving integer ambiguities. The technique, called LMS, is used to demonstrate that single-epoch integer ambiguity resolution is generally practical if 10 or more measurements are available and the modeling error in the double differen= is below 0.2 cycles. The teclmique is tested epoch-by-epoch with GPS-GLONASS Ll measurements collected at 5 second sampling rate over 24 hours with baselines of 2 km and 5 km. The current success rate is over 95% for the 2-km baseline, and about 80% for the S-km baseline. Comparable performance is achieved with GPS Ll- L2 measurements. With GPS-GLONASS L14.J all- in-view measurements, when available, the technique is expected to offer robust solutions with cm-level accuracy far navigation at a distance of lO- 25 km from a reference station.
