摘要高精度定位定向系统(Position&OrientationSystem,简称POS系统)能够获取机载传感器的空间位置和三轴姿态信息,从而定量化反演遥感信息获取过程,实现机载遥感直接对地定位(DirectGeoreferencing)。本文首先介绍POS与航空摄影系统的集成方法与工作原理;然后初步分析了POS系统的主要误差来源,在此基础上,研究了POS系统数据处理及误差控制方法;最后,结合河南安阳飞行试验数据的分析处理结果,进行了精度和可行性分析。

Abstract：By combination of GPS with Inertial Measurement Unit (IMU), Positioning Orientation System(POS) may conduct direct measurement of all parameters of the exterior orientation for airborne sensors so as to realize direct geo-referencing. This paper deals mainly with the integration of GPS/IMU with aerial camera, the data processing and the main error sources of POS. POS applied in the aerial photogrammetry is also analyzed on the basis of the results obtained from the test flight area in Anyang City, Henan Province.
