A Fast Search Algorithm For Carrier Phase Integer Ambiguity

In this paper, a fast search algorithm for carrier phase ambiguity is presented. The algorithm makes use of the least-square searching and integer Gaussian transform, and the number of ambiguity candidates is reduced. Five methods is applied to eliminate the incorrect ambiguity candidates. The reliability of the algorithm is improved and the searching time is reduced. Experiment results show that the algorithm can achieve fast search ability either under static condition or under kinematic condition.
