摘要

Firstly some main parameters of the star camera are designed by analysis to achieve high pointing accuracy, and then some important steps are described. A high-precision assembly and test system for this star camera are constructed in this chapter. Many measurement images are acquired by on-axis and off-axis star camera imaging test which are implemented with long focal length collimator’s image plane moving. The optimal focal plane position of this star camera is determined by a surface fitting method. The distribution character of the imaging points in the central and edge views is considered in this method. The sub-arcsec pointing accuracy is verified by test in orbit. The measurement result is consistent with the design value finally.
