Space Terma Star Tracker
T1 Star Tracker

SUITABLE FOR HIGH RADIATION MISSIONS

The T1 Star Tracker is based on the sensor chip Faintstar-2 which is a CMOS Active Pixel Sensor with a suite of integrated on-chip functionality supporting a completely new class of miniaturized high performance star trackers. The T1 is built with class 1 components and is suitable for high radiation missions, e.g., geostationary satellites with electrical orbit raising and 15 years in GEO. T1 has a separated baffle and camera for best thermal stability, and a separate data processing unit.

Star Tracker T3
T3 Star Tracker

SUITABLE FOR NANO- AND MICROSATELLITE MISSIONS

T3 is a very compact star tracker with high accuracy and excellent thermal stability ideally suited for nano- and microsatellite missions with lifetime in excess of 5 years. As a scaled-down version of the T1 Star Tracker, the T3 Star Tracker has a smaller optical system and computer processing unit that is based on highly reliable COTS components. The built-in processing unit in T3 Star Tracker accommodates the star catalogue and software algorithms for autonomous attitude acquisition and tracking.

OPTICAL GROUND SUPPORT FOR T1 and T2

The easy to install and simple to use Dynamic Ground Support Equipment (DOGSE) is developed for T1 and T3 Star Trackers. The DOGSE is highly compact and very low mass making it suited for both open- and closed-loop star tracker tests. The DOGSE can easily be adopted to fit any baffle, providing repeatable and stable mounting required for closed loop testing.
