TACAN stands for Tactical Air Navigation, a system that allows pilots to see the distance and direction to a ground beacon, usually at an airfield or carrier. It is 57 years ago that the first system was built and tested, based on the ideas and patents of Sven Dodington and college’s at ITT Nutley. The TACAN system operates on 126 channels between 1025 MHz and 1150 MHz for the downlink. The uplink is 63MHz lower for the first 63 channels, or 63MHz higher for the last 63 channels. Over 1000 TACAN beacons were commissioned since 1956, most of them are still operating.
