Aircraft rendezvous using low data rate two-way TACAN bearing information

摘要

Aircraft rendezvous is facilitated by operating airborne remote aircraft TACAN stations in the inverse bearing mode and using low data rate range interrogation and range reply signals for determining bearing. An aircraft determines its bearing to another similarly equipped aircraft by switching its antenna to an omnidirectional pattern and transmitting range interrogation pulses and then switching its antenna to a rotating directional pattern and receiving range interrogation and range reply signals from the other aircraft. The TACAN station calculates the bearing to the other aircraft using the low data rate signals, thereby obviating the necessity of using a high power base TACAN station.
