Abstract: A protective assembly that is adapted to provide temperature isolation for an electronic device is disclosed. The assembly includes a housing having a cavity with a top surface and at least one side surface. The housing is configured to accept an electronic device having a top and a bottom in the cavity with the top of the electronic device proximate to the top surface of the cavity. The housing is further configured to maintain a vacuum within the cavity. The assembly includes at least one support disposed within the cavity. The at least one support is configured to contact the housing only at a first point proximate to the top surface of the cavity and contact the electronic device only at a second point that is proximate to the bottom of the electronic device.

Abstract: A method and system for autonomous two-way RF communication between a launch vehicle and at least one receiving or tracking station. Detection circuitry continuously determines the identity of the optimum receiving or tracking station (ground, sea, airborne, or satellite) and selects the best launch vehicle transmission antenna to close the RF telemetry link. The method and system is designed to simultaneously transmit and receive RF signals. The antenna system includes a telemetry transmission link and an antenna selection link. Antenna selection link signals received by each antenna element on the launch vehicle are provided via RF couplers to a receiver for signal strength and modulation signal detection. The telemetry transmission link communicates with a receiving or tracking station by using a transmitter to drive one of two or more switched antennas mounted on the surface of the launch vehicle having the current higher signal strength.
