G PS接收机天线相位中心随不同截止卫星高度角变化对基线的影响

内容简介：分析了不同卫星高度角的观测值对接收机天线相位中心改正和基线解算的影响，理论分析和实验结果表明：对于中长距离的基线，采用天线指向北方向的方法仍不能完全消除天线相位偏心差造成的误差影响，因此该因素必须在数据处理中加以考虑。

Abstract：The influences of antenna phase eccentric error in different satellite elevation mask angles and differ-ent baseline lengths are analyzed.The research suggests that for the medium and long baseline,the method u-sing antenna towards north direction can not completely eliminate the antenna phase eccentric error,when satel-lite elevation angles of baseline at both ends are not the same,so the factor must be considered in data process-ing.
