摘要
针对立方星的姿态控制中,获取卫星当前姿态的需求,设计了一种用于立方星的数字式太阳敏感器。通过线性CCD(Charge Coupled Device)和对应的狭缝型光学通路设计,实现了对点状光源相对于安装平面的法线双角度测量,并达到了视场角度40°,理论测量精度为0.01°的设计指标。该太阳敏感器采用了商用现成品和技术(COTS:Commercial Off-The-Shelf),具有体积小、功耗低、设计简单、稳定性高和易于集成的特点。作为满足立方星子板几何尺寸的COTS资源,在未来的立方星研制过程中具有潜在的应用价值。
To obtain the current attitude of the satellite in attitude control of CubeSat,a digital sun sensor for CubeSat is designed. Through the linear CCD( Charge Coupled Device) and the corresponding slit-type optical path design,the double-angle measurement of the point light source relative to the normal line of the installation plane is achieved,and the design index of the field of view angle of 40° and the theoretical measurement accuracy of 0. 01° is achieved. The sun sensor uses commercial off-the-shelf products and technologies( COTS:Commercial Off-The-Shelf),and has the characteristics of small size,low power consumption,simple design,high stability,and easy integration. As a COTS resource that satisfies the geometric dimensions of the CubeSat circuit board,it has potential application value in the future development of the CubeSat and plays a vital role in the further research of other CubeSats.
