Integer Ambiguity Resolution Algorithm Based On Different Baseline Method

Abstract

Carrier phase observation can greatly improve the accuracy of navigation and positioning, but the existence of ambiguity will seriously affect the accuracy of the results. This paper analyzes the advantages and disadvantages of LAMBDA algorithm for integer ambiguity resolution. The problem of constructing search domain leads to long search time. An algorithm of integer ambiguity resolution based on long baseline and short baseline is proposed. By comparing the results of the algorithm, the applicability and accuracy of the algorithm are analyzed.
