实验表明，架设GPS基准站可以明显提高POS系统定位的高程精度，无地面基准站的POS系统定位结果可满足1∶50000小比例尺航测成图的精度要求。
The experiment results have verified that the setup of GPS base station can significantly improve height accuracy of positioning by POS. POS Positioning without GPS base station can meet the specification of topographic mapping at small scale under 1 ∶ 50 000 .
