卫星表面物体反射光对太阳敏感器的影响分析
Analysis for Effect of Satellite's External Object Reflected Light on Sun Sensor
摘要
Abstract
Sun sensor is the critical equipment of satellite attitude determination and control system,it may be affected by stray light such as satellite's external object reflected light. When the inflected light enters the field of view of the sun sensor,it may cause interference to the sensor and then causes the attitude control system to make a false judgment.Based on the analysis of overshadow by satellite and the characteristics of the reflected light,a quantitative method of calculating the intensity of reflected light is proposed in the paper. Taking a certain type of satellites as an example,reflectied light of satellite's external object into sun sensor is calculated,the measures to reduce the influence of reflected light by rea-sonably choosing thermal control materials are proposed.关键词
