一种快速求解整周模糊度的方法

针对FARA方法搜索整周模糊度组合数比较大,LAMBDA方法需要浮点解精度比较高的缺点,提出一种求解GPS载波相位测量整周模糊度的分步法。用LAMBDA方法搜索出来的整周模糊度作为FARA方法的初始解,进而用FARA方法解算出它的最终解。实验结果表明,该方法能缩短搜索整周模糊度的时间,快速准确地确定整周模糊度。

An Algorithm for the Quick Solution of the Integer Ambiguity of GPS Carrier Phase Measurements

There exist a big combination of solved integer ambiguity for the FARA method and a high accuracy requirement on the float solution for the LAMBDA method.In order to conquer the weakness this paper proposes a step solution for the integer ambiguity of GPS carrier phase measurements.The beginning value of the FARA method comes from the LAMBDA search.And the precise integer ambiguity is solved by the FARA method.Our test results indicate that the step solution can solve the integer ambiguity of GPS carrier phase measurements quickly.
