摘要

As man-made satellites grow continually smaller and smaller, new, lower mass, volume, and power solutionsmust be devised to give these satellites the same performance capabilities as larger satellites. One subsystem that isespecially difficult to shrink is the Attitude Determination and Control System (ADACS), which is used to positionthe satellite in a given orientation with respect to a specific reference frame. This paper explores a novel mechanismwhich combines both of these functions into one device. A permanent magnet is used in conjunction with thegeomagnetic reference frame to provide magnetic torque to change the spacecraft's attitude. By gimbaling themagnet, any desired attitude may be achieved. Experiments run in a simulated environment (air table) have beenused to test the effectiveness of this technique and the results are used to provide the design parameters for a spacequalified system for CubeSats.
