摘要
GEO轨道光学遥感卫星是光学遥感卫星星座的重要组成部分,其运行于地球同步静止轨道,具有大探测范围、高分辨率、高稳定性等技术特点。论文通过建立太阳光影响模型,结合ADC效能评估模型及卫星系统特点,对GEO遥感卫星工作效能进行建模分析。综合考虑系统可用性、可靠性及关键技术评价指标,通过仿真计算后得出该型卫星工作效能特点规律,并提出降低卫星本体故障率、加快卫星在轨故障诊断和提升探测器抗阳光能力建议,为后续该类型卫星建设提供指导和借鉴。
GEO orbit optical remote sensing satellite is an important part of optical remote sensing satellite constellation.It operates in geostationary orbit and has the technical characteristics of large detection range,high resolution and high stability.In this paper,through the establishment of solar impact model,combined with ADC efficiency evaluation model and the characteristics of satellite system,the operational efficiency of GEO remote sensing satellite is modeled and analyzed.Considering the system availability,reliability and key technology evaluation indexes,the working efficiency characteristics of this type of satellite are obtained through simulation calculation,and suggestions are put forward to reduce the failure rate of the satellite body,speed up the fault diagnosis of the satellite in orbit and improve the anti sunlight ability of the detector,so as to provide guidance and reference for the subsequent construction of this type of satellite.
