Explanation: Long range navigation is a hyperbolic radio navigation system operating at low frequencies. The hyperbolic navigation system in LORAN uses the time difference between radio pulses to locate the object of interest. An electronic clock was employed to generate trigger signals that maintain a fixed delay such as 1 ms between the transmitters.
