火星车在火星表面巡视时需对前进方向的方位角进行测量，“天问一号”火星探测器“祝融号”在火星车上采用了太阳敏感器实现方位角测量，火星表面太阳光强辐照度低且复杂，火星大气中和陆地表面遍布尘埃，太阳敏感器在火星表面应用时将面临复杂光强和多尘埃的特殊环境，为保证“祝融号”火星车在火面移动的安全，太阳敏感器进行了自适应光强设计和抗灰尘设计，并在地球表面开展了模拟设计验证试验，该款太阳敏感器已成功应用于“天问一号”火星探测器“祝融号”火星车，整个寿命期内产品在轨工作良好，有效保证了火星车导航需求。
When the Mars rover patrols the surface of Mars, it is necessary to measure the azimuth in the forward direction. The "Tianwen-1" Mars rover "Zhurong" has used a sun sensor to measure the azimuth on the rover. The solar intensity and irradiance on the Martian surface are low and complex, and dust is scattered in the Martian atmosphere and land surface. When the sun sensor is applied on the Martian surface, it will face a special environment of complex light intensity and dust. To ensure the safety of the "Zhurong" Mars rover's movement on the Mars surface, the sun sensor has been designed with adaptive light intensity and dust proof, and verification experiments have been carried out on the Earth surface. This sun sensor has been successfully applied to the "Tianwen-1" Mars rover "Zhurong". The Mars rover has been working well in orbit throughout its entire lifespan, effectively ensuring the navigation needs of the rover.
