Field tested and proven over many years and on multiple platforms, the TCN-500 is the latest technology airborne Receiver-Transmitter (RT) component of the Tactical Airborne Navigation (TACAN) system.

The TCN-500 RT measures the slant-range distance and relative bearing to a selected ground station or an airborne beacon and computes velocity and time-to-go to that station.

An optional configuration measures slant-range distance to up to three selected ground stations for RHO-RHO or DME-DME area navigation.
