摘要
本文简要介绍了ＧＰＳ辅助光束法区域网平差的基本原理和方法，详细讨论了太原航摄机动态试验场实际ＧＰＳ航摄飞行试验的结果。利用联合平差程序ＷｕＣＡＰＳ系统对试验区进行ＧＰＳ辅助光束法区域网平差，用分米级精度的ＧＰＳ摄站坐标获得了实地上平面为±７．９ｃｍ、高程为±１８．１ｃｍ的加密精度，充分显示了动态ＧＰＳ定位技术在航空遥感定位中的广阔应用前景。
This paper describes briefly the principle and method of GPS - supported bundle blockadjustmet. Some experiment results of an actual flight over test field Taiyuan are discussed. Theactual accuracy of kinematic GPS positioning is dm level. The test was done by using ourcombined adjustment program WuCAPS, some experimental results are drived from thecalculation by the method of the GPS-supported bundle block adjustment. The coordinateaccuracy reaches ± 7.9cm for planimetry and ±18. 1cm for height in the ground, which showsthe applicability and the economic benefit of kinematic GPS positioning in hight accuratephotogrammetric point determination.
