GPS／INS组合系统的工作原理及其在航空遥感中的应用现状

Principle of Integrated GPS/INS and Application Status in Aerial Remote Sensing

GPS／INS组合系统应用于航空摄影测量时可以直接给出相机曝光瞬间的外方位元素，从而部分乃至全部地摆脱传统摄影测量对地面控制点的依赖。本文主要介绍GPS／INS组合系统的工作原理及特点，以及GPS／INS组合系统辅助航空摄影测量与遥感的国内外应用现状。

The elements of exterior orientation at exposure split second can be obtained directly by using integrated GPS/INS in aerial photogrammetry. Thus,the relations of the aerial photogrammetry on the ground control points may be shaken off. Accordingly,the principle and features of the integrated GPS/INS at home and abroad are reviewed. The application status of the GPS/INS aerial photogrammetry and remote sensing is introduced in this paper.
