ABSTRACT:
A data network interconnects ships. At least one ship has sensors which track targets. The data rate over the network is reduced by transmitting hostile target tracks at a greater rate than friendly target tracks, by transmitting hostile target tracks that are closest to friendly assets at a greater rate than hostile tracks at greater distances from friendly assets, andor by predicting the location of a target from old track information previously transmitted over the network, and if the predicted location matches the actual sensed location, transmitting only a track update message, and if the predicted location does not match the actual location, transmitting a complete track update.
