Abstract:

Observation of Pageos, a 100 ft. diameter balloon satellite, indicate that driving torques must be acting on the body to cause the dynamic motions. This theoretical study tests one explanation of these torques. The proposed explanation is that solar radiation would heat the rotating satellite unevenly causing distortions in the surface. Momentum exhange getween solar photons and the distorted surface would then generate the required torques. A spherical model of Pageos was found adequate to explain the torque causing rotation but totally inadequate to explain the percession torque. An oblate spheroid, which is the time averaged model of the actual shape, was then used and proved to be very successful in predicting the precession torque. Author
