Definition of Thermal Control Surface Characteristics of Satellite Model C.

Abstract

Basic vehicle geometry, surface areas and thermal control surface characteristics and internal heat generation rates for the ERTS-1 were defined to permit generation of the intrared signature of the satellite under anticipated orbital conditions and operating modes. The ERTS-1, which operates in a 500 nmi altitude circular sun-synchronous polar orbit, uses both passive and active thermal control systems. Passive control is accomplished by the use of thermal control coatings (various white and aluminum paints) and insulation. Active control employs temperature-activated movable shutters to maintain the bulk of the electronic equipment between 17C (63F) and 25C (77F). Orbital temperature data are provided for some portions of the spacecraft.
