Geometry-free Ambiguity Success Rates in Case of Partial Fixing

P.J.G. Teunissen, P. Joosten, C.C.J.M. Tiberius

Abstract:	GPS ambiguity resolution is the process of solving the unknown cycle ambiguities of the carrier phase data as integers. It is the key to fast and high precision relative GPS positioning. Since unsuccessful ambiguity resolution, when passed unnoticed, will often lead to unacceptable errors in the positioning results, very high success rates are required for ambiguity resolution to be reliable. In this contribution we present and evaluate the probability of correct integer ambiguity estimation for the ionosphere-weighted geometry-free GPS model. Particular attention is given to a partial fixing of the ambiguities.
