Abstract:

The paper presents a new development method for Cholesky ambiguity search method.The method makes use of an ambiguity reparametrization, Cholesky decomposition and best cut.Experiment results show that the method can achieve fast search ability, and satisfy real time attitude determination and GPS/INS integration with GPS carrier phase measurement.

Key words: navigat ion, ambiguity, carrier phase, Cho lesky facto rizat ion
