【摘要】 本文利用 GPS三个天线的载波相位信息 ,先用三差法求出基线的初解 ,在此基础上再借助模糊度函数搜索初解 ,最后用双差法得到最终精确解 ,同时得出姿态角。文中主要结果是 :基线相对定位精度达亚毫米级 ,定向精度在 1米基线时为 0 .0 1度 ,基线越长 ,定向精度越高更多还原

【Abstract】 In this paper,GPS carrier phase was used with baselines in a three-antenna configuration to obtain high-accuracy attitude:First,tri-differential method was used to get the baselines’ raw results.Then with the help of AF(Ambiguity Function),we got the seaching results.Finally double differential equations were used to get the high-accuracy results.Experimental testing with ADU2 is demonstrating pointing accuracies below 001 deg (1σ,1m baseline) with static surveying.更多还原
