摘要: 针对机载遥感成像用分布式位置姿态测量系统(POS,Position and Orientation 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.

Abstract: Aiming at the precision alignment of distributed position and orientation system(POS) for airborne remote imaging, the errors which affect the transfer alignment accuracy and velocity were analyzed and the real circumstance of remote imaging was considered. Based on these, a transfer alignment method of distributed POS which uses the climbing course of aircraft was proposed and compared with other maneuver modes. The semi-physical simulation shows that good alignment accuracy can be obtained and the moving condition of aircraft is used efficiently. The investigative results would offer the principle foundation for design and choice of the alignment schemes of airborne distributed POS.
