摘要
对X射线天文卫星观测需求进行了分析,提炼了观测任务对观测模式、源的高精度定位与对准、轨道、热控、测控数传等多项需求与约束;针对X射线观测的多需求、多约束难点,设计了集巡天观测、定点观测与小天区扫描观测于一体的观测模式,解决了一颗卫星同时实现全天扫描、银道面深度扫描、重要惯性区域扫描、重要及机遇目标深度观测以及伽马暴全天监测的多种观测需求的难题,该技术已在我国硬X射线调制望远镜卫星上得到应用.
The requirements of the X-ray astronomical satellite observation mission are analyzed in this paper.The requirements for observation modes,high-precision positioning and alignment of sources,orbit,thermal control,telemetry and telecontrol,data transmission are refined.Observation mode including all-sky survey,pointed observation and area observation is designed in this paper,which achieves the goal of all-sky survey,galactic plane survey,important inertia area observation,opportunity target observation and gamma-ray explosion.This technology has been applied in hard X-ray modulation telescope.
