为了提高分析的效率和准确性,基于SolidW orks平台开发了一个卫星光学敏感器视场有效性分析工具.该工具用于分析敏感器在卫星任务期间是否会因为视场问题而失效,以及何时失效.敏感器有效性分析所涉及的问题有:有效性判断的3个层次——敏感器系统、敏感器组和单敏感器的有效性判断;遮挡问题——敏感器会受到卫星部件或目标的遮挡;反光问题——敏感器会受到行星反光和卫星部件反光的干扰;运动问题——包括目标、卫星本体、卫星部件和敏感器的运动.给出了解决以上问题的软件设计方案.介绍了有效性分析功能的实现原理.给出了分析过程的5个步骤:定义时间,定义目标,定义部件运动,定义敏感器和执行分析.最后给出了一个实例演示,验证了该工具的功能.
To improve the efficiency and accuracy of the analysis, a satellite optical sensor field-of-view validity analysis tool was developed based on the SolidW orks platform to analyze whether a sensor fails due to field-of-view problems during satellite missions and when Failure The issues involved in the effectiveness analysis of the sensor are: 3 levels of validity judgment - Judgment of validity of the sensor system, sensor group and single sensor; Blocking problem - The sensor is affected by satellite components or targets Reflective problems - sensors are subject to satellite reflections and satellite components reflective interference; Motion problems - including the target, satellite body, satellite components and sensor movement. Software design solutions to solve the above problems are given. The realization of the effectiveness analysis function is given.The five steps of the analysis process are given: defining the time, defining the goal, defining the movement of the part, defining the sensor and executing the analysis.An example is given to demonstrate the function of the tool .
