A GNSS integer ambiguity resolution method based on ambiguity domain search strategy

Abstract

A new integer ambiguity resolution method is proposed to solve influence caused by Ambiguity real solutions accuracy and high dimensions on LAMBDA search strategy. Its search efficiency is very close to bootstrap algorithm and the success rate is higher. The reason is that the new method set reasonable number of ambiguity reservation number. By using in conjunction with SE-VB method, it Narrows the initial search radius of SE-VB algorithm and effectively reduces the computation time. Finally, the comparison of bootstrap, SE-VB and the new method in a GPS precise positioning experiment further verifies the effectiveness of the new algorithm.
