基于单基线的GPS载波相位双差姿态测量模型,利用模糊度函数法,建立起适应度函数,采用十进制编码设计了能够避开整周模糊度的求解而直接搜索解算载体姿态的遗传算法模型。实测数据处理结果表明:静态条件下,航向解算精度达到0.30°(均方差),纵摇角解算精度达到0.40°(均方差),基线长解算精度达到0.30m(均方差)。可以证明算法具有潜在的动态姿态实时解算能力。
Based on the principle of attitude determination with single baseline, according to the carrier phase dual differentia mathematic model of attitude determination, in favor of ambiguity function method, the fitness function is established, then the decimal coding genetic search algorithm is designed. The static experimental result shows the algorithm is feasible and reliable, and the heading precision approaches to 0. 30° (RMS), pitch precision approaches to 0. 40° (RMS), baseline precision approaches to 0.30m(RMS). The algorithm is expected to work well in real time.
