摘　　要：利用GPS和高精度GAMIT计算软件,沿长江建立了以宜昌、监利、锣山、武汉4个地区的遥感控制点。每个测区采用设置长时间控制点观测,将其与武昌九峰GPS观测点进行联合处理,使得每个控制点的精度高于0.5m,保证了控制点精度满足1m遥感卫星图像的纠正要求。By utilizing GPS and high-precision GAMIT software, remote sensing control points in four areas of Yichang, Jianli, Luoshan, and Wuhan are established. Long time control point observation in every measuring area are used, and the observed data are processed with those from Wuchang Jiufeng GPS station. This method yields a precision higher than 0.5 m for each control point, which meets the requirement of the correction of 1 m remote sensing satellite image.

关 键 词：遥感图像 控制点 GPS
