| 摘 要： | 为提高GPS定位的精度，通过计算黑河区域地面已知三角控制点的WGS-84空间直角坐标与BJ-54空间直角坐标间的差值来解算出GPS用户设置坐标中三个转换参数，并采用GPS实测的高程和控制点实际高程分别进行坐标变换，经对比分析确定最终的GPS校正参数，从而保证了SPOT遥感图像处理、地面解译及研究应用的空间配准精度。

| Abstract: | In order to improve the orientation accuracy of GPS, three transform parameters of the user grid were obtained by calculating the difference between the space r ectangular coordinate of WGS-84 and BJ-54 for given triangle control points in H eihe region. The calibrating parameters of GPS were determined by coordinate tra nsform with comparison between the measured elevation of GPS and the actual elev ation of control points. The spatial calibration precision could be assured in t he SPOT image processing, image interpreting and study applications. |
