Modeling, test and correction of static pointing error for remotion platform

According to the axis offset, arosed by rotation of azimuth or pitching axis, was biggish than index in the test of certain remotion platform, the error sources were analyzed comprehensively. And then, a kind of error test and compensation plan was proposed based on this, multi-body kinematics theory was used to setup correction model of axis pointing deviation of the remotion platform. Subsequently, the test experiment of pointing deviation was designed to gain the actual pointing error, the unknown parameter of the correction model were obtained by measured data. Finally, model simulation and experimental test results after compentation both show that the horizontal axis offset error has been reduced from 176.1″ to 1″, the vertical axis pointing accuracy has been improved from 18″to 9″ after correction of error sources, and the error test and correction method has been successfully used in the actual test of the remotion platform, which satisfied the normal requirements.
