Star Tracker ST400

The ST400 is the bigger brother of the successful ST200 star tracker. It uses the same proven electronics but uses a different opto-mechanics. The ST400 trades an increased resolution for being a little larger than the miniature ST200. Like ST200, the ST400 has been developed in cooperation with Hyperion Technologies B.V. The ST400 delivers a full and autonomous attitude solution and is your attitude sensing solution for missions with demanding accuracy requirements.
