Star Trackers
Focusing on fully autonomous attitude determination with high accuracy
STAR TRACKERS FOR MISSIONS FROM LEO TO DEEP SPACE EXPLORATION
Our series of star trackers support space missions ranging from satellites with short mission lifetimes to satellites having long lifetimes and stringent requirements for radiation tolerance.
Autonomous high-accuracy attitude determination
Superior radiation resistance
Flight proven
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 or 2 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.

T3 Star Tracker
SUITABLE FOR MICROSATELLITE MISSIONS
T3 is a very compact star tracker with high accuracy and excellent thermal stability ideally suited for microsatellite missions designed for a lifetime of 5 years in LEO. 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 the T3 Star Tracker accommodates the star catalogue and software algorithms for autonomous attitude acquisition and tracking.

Dynamic Optical Ground Support Equipment (DOGSE)
OPTICAL GROUND SUPPORT FOR T1 AND T2
The Dynamic Ground Support Equipment (DOGSE), designed for T1 and T3 Star Trackers, offers a streamlined installation process and user-friendly operation. The DOGSE is highly compact and very low mass making it suited for both open- and closed-loop star tracker tests. The DOGSE can be adopted to fit any baffle, providing repeatable and stable mounting required for closed loop testing.
