A Family of Generic Earth Pointing Satellites

This paper outlines a family of generic earth pointing satellites. The smallest configuration is sized to fit a Get Away Special (GAS) container (2.5 cubic feet). The basic core of the largest member is sized to be scout launch vehicle compatible (18 cubic feet). The smallest member can easily accommodate 125 pounds of payload and generate 200 watts of electrical power. The largest can carry 500 pounds of payload and generate 1 Kilowatt of power. This family of earth pointing satellites is based on modular components that allow upward compatibility. To keep cost per unit volume low, tried and proven components are used which reduce testing of the integrated satellite. The modular design and standardization of power, and command and telemetry functions allow for ease of integration and system level checkout. The family limitations and their solutions are discussed as well as tradeoffs of various structural fabrication methods (metallic vs. composite vs. plastic).
