摘要
利用ＧＰＳ、姿态测量装置、扫描激光测距及同步的遥感器组成的机载遥感三维信息获取系统是新型的空地直接对地定位遥感系统，由于各种误差的存在而最终影响到三维定位结果。本文简要说明了空地直接对地定位的基本原理、重点分析了各个误差项及其对定位结果的影响，并进行了误差传播和精度估计，取得了重要的结论。
Airborne 3D remote sensing information acquiring system which integrates GPS、 attitude measuring sensor、scanning laser rangefinder and remote sensor into a complete remote sensing survey platform is a new remote sensing system with airtoground directly positioning system, but each of these four sensors may have error which can affect the georeferenced 3D position. The basic theory of the airtoground positioning system is briefed in this paper, specially we analyze the source of each error and its influence to the 3D positioning system, and then we derive the general error equation of this remote sensing system from the error propagation law and estimate its accuracy under different conditions, therefore we get some important conclusions.
