Abstract: “The design, manufacturing and calibration of an improved miniaturized two axis sun sensor for satellite attitude control is presented, including the manufacturing process using MEMS technologies. The high precision is obtained by the subdivision of the field of view (FOV). The FOV and the resolution obtained are ±60º and 0.5º for the coarse measure and ±35º with precision better than 0.1º for the fine measure.”
