The thermal control of the GEOS-A and GEOS-B satellites designed and built by APL has been considered successful. Additional volume and structure were added to the basic GEOS-AB reference in order to arrive at the GEOS-C configuration. The interior of the GEOS-C satellite consists of a more conductive heat transfer network and the spacecraft payload exceeds 700 pounds. In going to the GEOS-C configuration, it has been necessary to include the effects of the changes in orbit and internal heat dissipation profiles in the thermal design and analysis of the spacecraft. The design and analysis presented is that of the analytical results obtained from the Thermal Analytical Model. To complete the story, an addendum is planned to present new data as they become available from the spacecraft thermal vacuum testing and from post-launch telemetry. Author
