Loran-C: An overview of operational and propagation characteristics
Abstract
The Loran-C, a low frequency long range navigation system is discussed. The system's phase format and phase stability are important for navigation and time synchronization. Major calibration for the systems are oriented toward measurements. Loran-C pulse transmission allows distinction between ground wave and sky wave transmission. The pulse provides a transient capable of validating transient propagation theory. It is shown that the Loran-C transmissions are effective diagnostic tools for validating ground impedance and topographic models used in propagation theories.
