摘要
星敏感器是当前广泛应用于航天器姿态测量的高精度光学敏感器。小型化、低功耗、高精度、高更新率是现阶段星敏感器发展的共同特点。介绍了APS图像传感器的特点,并将其与CCD进行了详细的比较。对APS图像传感器的重要特性参数进行了分析,并介绍了一种由北京控制工程研究所研制的小型化高精度APS星敏感器及其设计方法。介绍了适用于GEO轨道的APS星敏感器图像在轨校正方法和APS图像传感器的发展方向。
Star sensor is the high precision optical sensor which is widely used in attitude measurement of the spacecraft nowadays. Low volume, low power consumption, high precision and high update data rate are common features of the development of star sensor. The key features of APS detector and a detailed comparison between APS and CCD are presented, and the main characteristics of APS detector are analyzed. A prototype of high precision APS star sensor and the design technique of the high reliability for GEO orbit star sensor are introduced. An error correction method in orbit and the directions of the development of APS detector are introduced.
