  • Patent number: 8885693
    Abstract: An automated process to periodically check and ensure that earth terminal settings provide compliant EIRPSD. For example, one embodiment of the present invention provides an apparatus which queries the modem for its transmit symbol rate and the Block Up-Converter (BUC) for its RF output power. Using these two values and preprogrammed values for connection loss between the BUC and antenna, the current input power spectral density being transferred to the antenna is computed by the apparatus and compared to the preprogrammed regulatory limit for the specific antenna. If the limit is being exceeded, the apparatus sets BUC attenuation to compensate for the excess.

  • Patent number: 6188367
    Abstract: A device for positioning an antenna on a vehicle. The device includes a first motor-driven timing belt connected to opposite sides of the antenna frame for rotating the antenna about its elevational axis. A constant force spring or a cam compensates for changes in belt path geometry as the antenna rotates. A second motor-driven timing belt is wrapped around a perimeter of a base plate for rotating the antenna about its azimuth axis. Electrical signals for the antenna and the drive motors are multiplexed and passed through a single coaxial cable in a rotary joint along the axis of azimuth rotation.
