摘要: 在观测时间和观测地点确定, 姿态测量系统保持基准姿态情况下, 可预先计算出某颗星体在系统视场中的运功轨迹和时间信息。以此为依据, 调整设备基座, 使星体的实际运动轨迹和计算轨迹重合, 并且时间信息保持一致, 建立系统的基准姿态。通过计算测姿系统输出信息和基准姿态间的偏差, 提出并实现一种高精度姿态测量技术的静态检验方法。对姿态测量设备的系统误差进行了精确检测, 并对系统输出的三轴姿态信息予以订正。计算结果表明: 航向角、横摇角、纵摇角均方差分别为19.98″、11.43″、12.05″, 该方法检验精度可达角秒量级, 精度较高。Abstract: In the case of specific observation time and place, the attitude measurement system was assumed in reference attitude, and the trace and time informations of one star could be calculated in advance.The actual movement trace and time information of star were made in accord with calculated trace by adjusting equipment base, and reference attitude was established.The output information of attitude measurement system was compared with reference attitude, and a static test method of high-precision attitude measurement technology was proposed and carried out.The system error of attitude measurement equipment was detected exactly, and the triaxial attitude information of system output was corrected.Calculation result shows that the mean-square deviations of heading angle, roll angle and pitching angle are 19.98″, 11.43″, 12.05″ respectively, the static test method can achieve the accuracy of arc second, and its precision is higher.
