Integer ambiguity solution based on artificial swarm algorithm
Shugang Liu, Yajing Zhang · 2016
One of the keys to precise position of using double difference carrier phase measure is to resolve integer ambiguity.Least-square ambiguity decorrelation adjustment(LAMBDA) is relatively fast and precise in integer ambiguity resolution of double difference carrier phase measurement.The LAMBDA consist of two aspects: decorrelation and search.In this paper, the artificial fish swarm algorithm(AF), a global optimization algorithm, will be used for search to obtain effective integer ambiguity.Simulation data are processed by the proposed algorithm using MATLAB and the results show that the integer ambiguity resolution method based on AFSA has high search efficiency and strong robustness.
