摘　　要：原始卫星遥感影像中包含严重的几何变形,几何粗校正不能满足制图要求,必须进行几何精校正。几何精校正依赖一定数量的地面控制点,本文在应用RBN/DGPS采集地面控制点的过程中,结合地理信息系统技术开发了RBN/DGPS导航与数据采集系统,该系统一方面针对手持GPS导航功能的不足,使用基于粗校正遥感影像的导航方式,实现路线导航功能,帮助测量人员准确、快速地找到已设计的控制点,另一方面实现坐标数据采集功能,提出了判断数据稳定性的采集算法并实现了数据的自动处理。There is geometric distortion in original remote sensing imagery, but geometric sketchy correction can＇ t satisfy the demand of cartography, so geometric precise correction is needed. Geometric precise correction depends on some ground control points collected by means of field surveying using RBN/DGPS. During the course of surveying, the software is developed based on the technique of geographical information system and can realize dual-purpose application with one RBN/DGPS. On the one hand, the navigation method of using sketchily corrected remote sensing imagery is used in allusion to the shortage of the navigation function by Handheld GPS. Therefore, the function of route navigation is realized and the surveyor can find the ground control points accurately and quickly. On the other hand, the function of coordinate data collection is implemented, the arithmetic of estimating the data stability is researched and the automatic data processing is realized.
