| 摘 要： | 惯性敏感器与星敏感器组合定姿是航天器高精度姿态确定的常用手段。通常将惯性敏感器的常值漂移作为扩展状态进行标定,而将星敏感器的常值偏差作为扩展状态进行估计也是可能的。本文对这两种方法的定姿精度进行了分析比较,给出了选用的准则。

| Abstract: | Usually a highly accurate attitude determination system is composed of inertial sensors and star sensors. In attitude filters , the constant drifts of inertial sensors are commonly treated as the expanded states to estimate, whereas the constant deviations of star sensors can also be estimated in the same way. The two calibration methods are compared and some choosing rules are given. |
