FY-2气象卫星在轨管理工程测控关键技术(上)

介绍了风云二号(FY—2)地球静止轨道自旋气象卫星工程测控的关键技术。分析了位置保持、姿态确定、星蚀和日凌的原理，给出了位置保持、姿态控制策略和地影、月影、日凌预报算法。并提出了一种检验定姿结果正确性的方法，提供了相应的工程计算参数。这些策略都已成功地用于FY—2卫星的在轨管理工程测控。

Key Technologies of Engineering Control on Managing On-Orbit FY-2 Geostationary Meteorological Satellite(Ⅰ)

The key technologies used to control FY-2 geostationary meteorological self-spin stabilized satellites were introduced in this paper. The principles of station keeping, attitude determination, earth shadow, lunar shadow and sun transit outage were analyzed. The maneuver strategies for orbit and attitude control and algorithms to predict happening of eclipse and sun transit outages were provided. Moreover, a new way to confirm the correctness of attitude calculating result was given, and many engineering data and examples were presented here. All these were successfully implemented in managing and controlling FY-2 satellites.
