ABSTRACT:
A geostatic satellite comprises a spinning drum for stabilization which spins around an axis of rotation which is parallel to the axis of the earth. A paddle member loaded with solar cells is directly rotatable about the same axis and is controlled such that the solar cells face the sun. A despun platform supports communication gear and maintains the gear pointed to a relatively fixed point on earth. A shading device for shading the electronics laden despun platform from the sun, is attached to the paddle member and rotatable therewith. Thereby, the shading device will always be disposed between the sun and the despun platform.
