Thermally insulated satellite reflector assembly

摘要

The invention is directed to a reflector assembly in a satellite system including a reflector having a reflecting surface and a back surface. The back surface is opposite the reflecting surface and has a plurality of ribs extending transversely therefrom. The reflector further includes a heater assembly embedded therein. The reflector assembly further includes a layer of closed cell plastic foam insulation which covers the heater assembly within the reflector. An inside surface of the insulation is disposed adjacent to the back surface of the reflector and includes a plurality of grooves. The plurality of grooves are configured to receive the plurality of ribs therein. The layer of insulation also includes a coating of ultraviolet radiation protectant disposed over an outside surface of the insulation.
