基于单基站、双基站差分定位及精密单点定位技术，对海岛区域的机载GPS定位数据进行解算。实验表明：基站距离影响差分定位的精度，双基站差分定位可以改善高程精度；机载GPS精密单点定位的精度与差分定位的精度在平面中偏差在0．10 m以内；在高程方向偏差在0．15 m以内。

This paper researched the method of processing airborne GPS measuring data based on single base-station, double base-station and precise point positioning ( PPP) in island area.The experiment shows that the distance of the base-station effect the pre-cision of differential GPS positioning and double base-station improve the altitude precision.The precision of PPP and differential GPS for Airborne GPS positioning is differ 0.1 m in plane, and 0.15 m in height.
