An improved integer ambiguity decorrelation algorithm

The solution of integer ambiguity was regarded as a key technology of precise attitude measuring algorithm, which rapidity and accuracy is influenced by the relevance of ambiguity vector. Since the deficiency of present decorrelation way in LAMBDA algorithm, it was hard to solve. This paper used a sort way to optimization the method of decorrelation, and improved the iterative process of LLL and white filter algorithms iterative process improvement. The simulation results shown that the optimized of decorrelation algorithm was suit for the LLL and white filter algorithms. And the settlement effects were better to relevance with a higher success rate.
