Description
The SITAEL Sun Sensor is a low cost attitude determination device suitable both for LEO and GEO orbits. Each Sun Sensor group is capable to estimate the Satellite-to-Sun vector with 1 deg (up to 0.1 deg when sunlight is perpendicular to sensor’s surface) of accuracy. The Sun Sensor is a 4-Quadrant Sensor (4-Q) based system, with a wide angle pinhole frontend able to guarantee increased precision, light power, and field of view. On-board a microcontroller acquires the 4-Qs data and applies the correction algorithms in real time
