Each of the sensors, actuators, and one or more control units are located at a fixed position in the system relative to one another. Each of the plurality of sensors and each of the plurality of actuators are coupled to at least one of the one or more control units via a plurality of wireless paths. Each of the plurality of sensors are operable to transmit the sensor data in an assigned time slot to at least one of the one or more control units over a plurality of wireless channels in each of the plurality of wireless paths.

    摘要: A method of communicating over a network for wireless communications is disclosed. The method transmits encoded data from a source device to a destination device via a single path up through a plurality of wireless paths using a random frequency hopping tuning pattern for wireless communications, and pseudo-randomly varies dwell times of the frequency hopping tuning pattern over which the data is transmitted. The network uses forward-error correction coding redundancy within a data burst to allow recovery of corrupted data in any partially jammed hop of the transmitted data.

    摘要: A transponder-based beacon transmitter system in an unmanned aerial vehicle is provided. The transponder-based beacon transmitter system comprises a global positioning system interface communicatively coupled to receive position information indicative of a current location of the unmanned aerial vehicle, a message formatter communicatively coupled to the global positioning system interface, and a transponder-based beacon transmitter. The message formatter formats vehicle identification of the unmanned aerial vehicle and the position information indicative of the current location of the unmanned aerial vehicle into an automatic dependent surveillance broadcast mode-select squitter message. The message formatter operates in one of a military mode, a National Airspace System mode, and a combined military/National Airspace System mode. The transponder-based beacon transmitter transmits the automatic dependent surveillance broadcast mode-select squitter messages from the unmanned aerial vehicle. Receivers in the vicinity of the unmanned aerial vehicle receive unsolicited vehicle identification and location of the unmanned aerial vehicle.

    摘要: A method and system for communicating using pulsed radar signal data links is disclosed. The method comprises encoding downlink data with a signature sequence as a secondary function onto a continuous wave pulse signal having a primary function at a master device. The data-encoded pulse signal from the master device is interpreted at one or more slave devices configured to receive the pulse signal within a first communications bandwidth of the primary and secondary functions. The master device synchronizes returning communication transmissions from each of the one or more slave devices for the secondary function within a prescribed return interval of the primary function.

An adaptive channel operable to communicate messages between the node and the neighbor nodes is established. One or more bearer channels are selected. The one or more neighbor nodes are notified of the one or more selected bearer channels using the adaptive channel. The node and the neighbor nodes communicate over the bearer channels.
