The longest serie of sun sensors in Europe
Since 20 years, Airbus Defence and Space is manufacturing Analogue and Digital Sun Sensors.
250 units have already been ordered on Communication, Earth observation and Scientific satellites, and among them 120 are already in orbit, cumulating more than 400 years without failure. Those figures give to AIRBUS DEFENCE AND SPACE a leading position in Europe for sun sensors
This experience was gained with three products :
Space sensors like sun sensors units shall be tested deeply on the ground to guarantee their performance capability into orbit. The qualification and acceptance tests shall be as far as possible representative of the space environment.
In consequence, AIRBUS DEFENCE AND SPACE has developed test facilities, like representative sun simulators (0.5 sun intensity, same spectrum, same apparent angle), rotating table (1 arcsecond accurate), thermal chambers (-100 °C/+100 °C) and calibration procedures to test sun sensors in space representative environment.
