针对机载遥感成像用分布式位置姿态测量系统(POS,Position andOrientation System)精确初始对准的问题,结合遥感成像的实际作业情况,在分析影响传递对准精度和速度的误差源的基础上,提出一种利用载机爬升段进行分布式POS传递对准的方法,并与多种机动方式进行对比.半物理仿真结果表明:利用遥感载荷作业现有条件能够获得数学平台失准角和安装误差角的准确快速估计.研究结果可为机载分布式POS传递对准方案的选择和设计提供理论参考.
Aiming at the problem of accurate initial alignment of Position, Position and Orientation System (POS) for airborne remote sensing imaging, combined with the actual operation of remote sensing imaging, based on the analysis of the error sources that affect the accuracy and speed of transmission alignment, A new method of distributed POS transfer alignment using carrier climb is proposed and compared with a variety of maneuvering methods.The results of the semi-physical simulation show that the mathematical platform misalignment angle and installation error can be obtained by using the existing conditions of remote sensing load operation Accurate and rapid estimation of angle.The research results can provide theoretical reference for the selection and design of the distributed on-board distributed POS transfer alignment scheme.
