The effects of propagation of the accuracies of positions determined using Omega in the UK
Abstract
Error correction derived from the ONSOD Omega prediction method were applied, an improvement in accuracy, and a different correction method, in which the Omega data are combined with position determination from a satellite navigation system are considered. The signals from three Omega transmitters located on different continents were monitored at three receiving sites in England. Lines of position (LOPs) are derived from the relative phases of the received signals and the intersection of the LOPs yields to receiver location. The derived receiver positions are compared with the known true position of the receivers and the error is determined. Diurnal and seasonal changes in position errors are obtained for all three receivers. At the most northerly receiving site, the magnitudes of the errors are different from those observed at the other two locations.
