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.
