Attitude Control Sensors

AASTR

AASTR

The A-STR and AA-STR are medium Field of View (FOV) star trackers integrated in a single assembly with a radiation hardened design.
S3 (Smart Sun Sensor)

S3 (Smart Sun Sensor)

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

Spacestar

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

IRES

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).
