    Abstract: Methods and apparatus for transmission of configuration information in a wireless communication network. A method is provided for transmitting a configuration message to a plurality of terminals in a wireless network. The method includes assigning a slot in a transmission to contain the configuration message, and transmitting a marker to identify the slot in the transmission to the plurality of terminals. The method also includes transmitting the configuration message in the slot of the transmission using a high data rate so that air-link resources are conserved.

    Abstract: A self-correcting mobile antenna control system and method. A method is provided for controlling the direction of an antenna mounted on a vehicle. The method includes determining a position decision based on a direction change signal output from a direction sensor, determining an energy decision based on a signal strength indicator, combining the position decision and the energy decision to produce an antenna control signal, and adjusting the antenna's direction based on the antenna control signal. The system also operates to periodically calibrate itself to offset any sensor errors so that intensive calibration procedures can be avoided.

    Abstract: A system and method for determining a signal propagation delay between a transmitter and a receiver, and for adjusting a transmission time based on the propagation delay. A central station inserts a marker into a transmitted signal at a time corresponding to a received timing signal. The MCT receives the signal from the central station and determines a time difference between receipt of the marker and the detection of the time interval event. A transmission by the MCT is adjusted by an amount of time proportional to the time difference.

    Abstract: A method an apparatus for selecting a forward link and return link data rate for a constant power, variable data rate two-way, mobile satellite communications link. The forward link and return link signal strength (in the form of carrier power to noise power spectral density ratio) is measured, cataloged, and the values are used for the data rate selection. In addition, a ping can be sent by the network operation center to the mobile unit and the response to the ping is used for updating the information of both forward link and return link signal strength, so the chance of wrong data rate selection can be reduced. Multiple re-transmission attempts combined with gradually increased re-transmission margin ensures the proper data rate decision can be eventually achieved even with occasionally inaccurate signal strength information.
