太阳敏感器是卫星姿态控制系统中常用的一种光电敏感器.当卫星控制系统转入应急模式时,太阳敏感器的宽视场快速捕获太阳尤为重要.本文设计了一种梯形狭缝式太阳敏感器,该敏感器具有大的检测视场(157°)且可满足大太阳角(最大175°)下的应用,而采用梯形狭缝设计可大幅度减小太阳角大范围变化对太阳脉冲宽度的影响,从而便于后续处理电路的设计.实际的在轨飞行试验中验证了这种太阳敏感器的实用性.
太暘敏感器是衛星姿態控製繫統中常用的一種光電敏感器.噹衛星控製繫統轉入應急模式時,太暘敏感器的寬視場快速捕穫太暘尤為重要.本文設計瞭一種梯形狹縫式太暘敏感器,該敏感器具有大的檢測視場(157°)且可滿足大太暘角(最大175°)下的應用,而採用梯形狹縫設計可大幅度減小太暘角大範圍變化對太暘脈遲寬度的影響,從而便于後續處理電路的設計.實際的在軌飛行試驗中驗證瞭這種太暘敏感器的實用性.

Sun Sensor is a kind of popular photoelectric sensors in satellite aRitude control system.It is very important to have a large field of view for the sun sensor during the course of the sun acquisition of the satellite working in the emergence mode.A ladder-shaped narrow slit sun sensor is presented,which has a very large field of view(157°)and is suitable for the application with the large attitude angle(≤175°).The design of ladder-shaped narrow slit can decrease the sensors output pulse widths which vary largely with the attitude angle,and be convenient for the correlative circuit design. The onboard experiment validates the practicability of the presented lun sensor.
