Abstract: According to the demand of mapping precision by satellite, a high-precision timing system of AOCS, which is based on the synchronous pulses latching and afterwards processing, is discussed in this paper. Due to the time mark arithmetic of star sensors and gyros, the error sources are analyzed. The result shows the timing system is helpful for the mapping precision.
