The A-STR is a medium Field of View (FOV) star tracker integrated in a single assembly with a radiation hardened design. The tracker features robust and accurate three axis attitude determination with very low mass and power consumption for the class of instrument.
More than 100 A-STR FMs have been sold for GEO, LEO and inter-planetary missions since 2001 and more than 90 years of successful operations in space have been accumulated to the date.
The high performance of its CCD detector means that the A-STR can be used in extremely accurate pointing space telescopes and in agile (or spinning) satellites. This is achieved via the A-STR’s dedicated operative modes that can be entered via telecommand.
