Abstract:

In order to equalize the satellite skin temperatures and increase solar cell efficiency, an attempt is made to precess the satellites spin vector perpendicular to the solar vector and maintain it in that position, using a magnetic torquing system that requires no commands from the ground. The advantage of this orientation to a high area thermal-mass ratio satellite with no batteries aboard is a temperature balance more favorable to power conversion. The orientation is to be accomplished by controlling the magnitude and direction of the satellites magnetic moment, which will be aligned with the largest principal moment of inertial approx 1.5 kg - sq m of the satellite coincident with the spin axis. This magnetic moment will interact with the earths geomagnetic field to produce a controlled orientation torque. Author
