Abstract:	In this article we present a new algorithm for real-time kinematic applications, implementation technique and test results (patent pending). The algorithm includes the following steps: extrapolation of the reference station observables; a recurrent procedure of averaging float ambiguities (using both code and carrier phase data); cycle slip detection and correction; ambiguity resolution; and finally, calculation of the baseline. Experimental results including statistical data on the baseline accuracy are presented. The effect the number of satellites, dual frequency data, and multipath have on RTK performance is studied as well. Some particular problems related to using combined GPS/GLN data are also examined in this article.
