Micro Attitude Star Tracking (MAST) Sensor

Conventional attitude sensing consists of a two step approach where a low bandwidth star sensor provides inertial attitude updates to a high bandwidth gyro. This approach has 4 major drawbacks: (expense, mass, power and limited bandwidth). SSG is proposing a revolutionary approach to attitude measurement that capitalizes on our extensive optics and precision mechanism experience. This Micro Attitude Star Tracking (MAST) sensor overcomes the disadvantages of the current attitude measurement approach with the possibility of providing accurate (1's of arc-sec), high bandwidth attitude data (1000's of HzA) with a low mass (1's of kg) low power (10's of W) and Low cost ($100k's) in a small package.
