Abstract: The present disclosure refers to a waveguide electromechanical relay switch having a rotor with transmission paths and an axis of rotation parallel to the base plane combined with an actuator adapted to the configuration. A 4-pol switch design enables compensation of fault cases in a relatively shortened length of transmission line, reducing potential RF loss. In one embodiment, a 4-pol rotor includes an offset transmission path that enables crossing of another path on the same rotor, providing increased functionality and fault-case recovery.

Abstract: A satellite thermal management system for dissipating excess heat generated within a satellite. The thermal management system includes a central platform for mounting heat dissipating components. A first thermal radiator panel and a second thermal radiator panel are mounted to the central platform. The first thermal radiator panel is arranged to face East when the satellite is in orbit. The second thermal radiator panel is arranged to face West when the satellite is in orbit. The first and second thermal radiator panels are thermally coupled to the central platform and are configured to radiate heat dissipated by the heat dissipating component mounted on the central platform.
