In a TACAN system, what is the receive frequency in relation to the transmit frequency?

In a TACAN (Tactical Air Navigation) system, the receive frequency is specifically related to the transmit frequency by a set value. For TACAN, the ground station transmits a signal at a frequency that is either 63 MHz above or below the frequency used by the aircraft's receiver. This frequency separation is crucial for the proper functioning of the TACAN system, ensuring that the signals can be effectively interpreted and that navigation data can be accurately relayed to the aircraft.

This predetermined frequency difference allows for clear signal processing, enabling pilots to determine their distance and bearing relative to the TACAN station. It establishes a consistent method for navigation aiding, which is vital for flight safety and operational efficiency. Understanding this relationship is important for pilots and navigators who utilize TACAN for precise navigation, especially in complex flight environments where accurate positioning is necessary.
