Propagational Assessment of VLF Navigation Signals in North America and the North Atlantic.

Requirements for vlf navigation signals are summarized. Various signals, both vlf communications and Omega and both day and night, are evaluated theoretically. Signal-to-noise ratio and signal structure are considered. Special attention is directed toward the continental United States, the North Atl...

Description
Summary:Requirements for vlf navigation signals are summarized. Various signals, both vlf communications and Omega and both day and night, are evaluated theoretically. Signal-to-noise ratio and signal structure are considered. Special attention is directed toward the continental United States, the North Atlantic, and Alaska. Numerous useful signals are available, but potential cycle slippage is indicated on most vlf communications signals.
