摘要
针对短基线静态定向,提出了一种通过基于载波相位双差观测方程,对俯仰角与方位角的搜索,在适应度函数取得 最大值的情况下搜索正确姿态角,确定整周模糊度,进行精密定向测姿.同时论述了搜索原理及其应用的具体过程,有效的提高了搜索效率.在基线长度为2.3m时,通过大量试验解算姿态角,测试结果表明该方法在短基线下测试精度与 稳定性均可满足要求.
Aiming at the short baseline static orientation, a method of searching the pitch angle and azimuth angle by searching the equation based on the carrier phase double difference observation equation, searching the correct attitude angle in the case of obtaining the maximum value of the fitness function, determining the ambiguity of the whole cir-cumference, Precision orientation. At the same time, it discusses the specific process of the search principle and its ap-plication, and effectively improves the search efficiency. When the baseline length is 2.3m, the attitude angle is solved by a large number of experiments. The test results show that the test accuracy and stability can meet the requirements at the short baseline.
