Abstract :
A rapid algorithm for GPS ambiguity decorrelation is proposed by analyzing some typical algorithms for GPS ambiguity decorrelation. The ordering process, integer LDL factorization and ambiguity screen of the algorithm are introduced. The algorithm´s performance is compared with others. Finally, the algorithm´s high performance and reliability are demonstrated. It is concluded that the ordering screen decorrelation method makes the discrete search of integer ambiguity resolution on the fly more efficient.
