Abstract
Present novel and non-trivial apparatus and method for generating low latency position information from position signals transmitted in a narrow bandwidth channel of a radio frequency are disclosed. An aircraft (i.e., ownship) and each target (e.g., aircraft) of a time-division multiple access (“TDMA”) network receives its respective position derived from its individual source such as a satellite navigation system. A processing module of a communication device installed in ownship and each target generate position signals, and during the allocated time slots of an interface protocol, exchange position information with the others in the network over a narrow bandwidth channel (e.g., bandwidths of 25 KHz or less) of a radio frequency in the VHF range or lower UHF range. The interface protocol may also be comprised of a voice contention time slot for the transmission of messages and an order wire for the administration of the network.
