Tacan Beacon Simulator.


vintage Tacan simulator

TACAN Beacon Simulators were quite big in 1955, like this one from Hoffman.

The cabinet is about 5 feet tall ( 1.7m).


The simulator replaces the antenna of the airborne set under test, and can transmit and receive on all 126 X channels.

Any bearing can be set, even a slowly changing bearing.

Any range can be simulated as well, including a changing range at up to 4000 knots.

The reply efficiency can be varied from 0 to 100%.
