Abstract

The space technology experiment and climate exploration satellite is a small satellite mission of China. A new star tracker and an ASTRO 10 star tracker were loaded on the space technology experiment and climate exploration satellite to test the new star tracker's in-flight performance. But the aberration correction function of the test star tracker is off during its experiment mission. Thus, the aberration effect should be considered in the evaluation of the test star tracker's performance. This study researches on the aberration correction for the star tracker's attitude measurement and deduces the aberration correction method based on attitude quaternion data. The inter-boresight angle and the relative Euler angle results show that the aberration of the test star tracker's attitude has been corrected successfully. The low-frequency errors of the test star tracker are also analyzed in this paper.
