About
The ST200 is a highly successful and miniaturized autonomous star tracker, developed in cooperation with AAC Hyperion. It is specifically designed for CubeSats and other sophisticated nano-satellites, offering a complete and autonomous attitude solution for missions with demanding size and volume restrictions. With over 200 units delivered to customers, the ST200 has a proven space heritage dating back to 2014. It boasts an accuracy of 10 arcsec, an update rate of 5Hz, and a limiting magnitude of 6.0. The star tracker has a sun exclusion angle of 40° and offers data interfaces via UART (TTL) with an optional RS422. It is remarkably compact, weighing only 106g and measuring 50x50x83mm, with a design life of 5 years.
