  • Voice call group function for a satellite based air traffic control system
    Patent number: 6185430
    Abstract: Voice call group functionality is provided in a satellite based air traffic control system to allow air traffic controllers and pilots of one or more aircraft to establish and maintain voice communication over a group call. A pilot of an aircraft may maintain voice communication with the same air traffic controller the entire duration of the flight over the entire globe. Voice communication between the pilot of an aircraft may be handed off from one air traffic controller to another by switching voice call groups. The voice call group functionality allows an air traffic controller to communicate simultaneously with pilots of different aircraft, and also allows pilots of different aircraft to communicate with each other.

  • Satellite based high bandwidth data broadcast
    Patent number: 6151497
    Abstract: A satellite based broadcast data communications service for a satellite communications system is presented which allows a data information service provider (40) to send large blocks of data information to mobile subscriber units (50). A satellite gateway (30) is coupled to a service provider (40) via a ground link (42) and to a satellite communications network (10) via a gateway link (36). A mobile subscriber unit (50) is coupled to the satellite communications network (10) via both a message link (56) and a high-speed high-bandwidth downlink (58). The mobile subscriber unit sends a data request for requested data information to service provider (40) via message link (56), satellite communications network (10), gateway link (36), gateway (30), and ground link (42).

  • Avionics satellite based data message routing and delivery system
    Patent number: 6147980
    Abstract: A data message routing and delivery system for an air traffic control system includes a communications network with one or more ground processing nodes, one or more satellite processing nodes, and one or more avionics processing nodes each configured to send and receive data packets to and from others network processing nodes in the communications network. One or more transmission prioritizing controllers are provided to determine the locations of each of network processing node, and to control access to communication channels and routing of data messages in order of priority between the network processing nodes. An application executing on one network processing node is send to an application executing on another network processing node under the control of the transmission prioritizing controllers.
