South Pacific Omega Validation Analysis
Abstract
This report, the sixth in the Omega Validation series assesses the Omega Very Low Frequency radio navigation system performance in the South Pacific Ocean area. Our general overview describes (1) a new emphasis for this and following validations on establishing signal quality through characterizing zones of signal-self-interference, (2) validation planning, (3) measurements and (4) analysis undertaken. Regions of self interference due to equatorial zone propagation are predicted, and analyzed for each Omega signal. Zones of signal interference caused by propagation the long way around the world (long-path) are predicted and assessed. Navigation accuracy and signal coverage is assessed. For most of the validation region Omega fully meets navigation expectations. The prediction guidance in the form Propagation Phase Corrections, zones of poor signal quality (Modal and Long-Path), and Station Coverage are largely correct. A relatively small but significant zone assessed. Confirmation however, was essentially circumstantial because no data was available within or close to the predicted zone. (RRH)
