Attitude Control Sensors
L'A-STR e l'AA-STR sono sensori di assetto di medio campo visivo integrato in un unico assieme progettato per resistere alle radiazioni.
S3 (Smart Sun Sensor) is a two axes solar sensor based on an Active Pixel Sensor (APS) detector. S3 has been optimised for the commercial market of Earth Observation satellites and, thanks to the intrinsic radiation hardness of the detector, for the GEO Telecommunication spacecraft.
SPACESTAR is a novel star tracker architecture, originally developed for a high volume constellation program which, through an integrated configuration to Attitude Control System computers, enables significant size, weight, power and cost benefits.
IRES is a two axis infrared Earth horizon sensor for accurate measurement of pitch and roll attitude angles with respect to the Earth disk centre. It is used in three-axes stabilised spacecrafts operating in GEO (Geostationary Earth Orbit)and MEO (Medium Earth Orbit).
