短基线约束条件下的整周模糊度二维搜索算法
Planar Search Algorithm for GPS Ambiguity Resolution with Short Baseline Length Constraint
摘要
Abstract
A new planar search method for GPS ambiguity resolution with short baseline length constraints was proposed. The integer ambiguity was fixed in the condition of least square error by searching the baseline elevation and azimuth angle. The model was established, the search principle and application process of the new algorithm were discussed, and the step of extensive search and intensive search was induced. Through the experiments and comparing with LAMBDA algorithm, the new method with simple algorithm and high efficiency was proved. The error is no more than lcm in baseline precision, no more than 0. 6" in elevation precision and no more than 0. 4?in azimuth precision. This method is also adaptive to attitude measurement.关键词
