INSTRUMENTATION OF THE NRL DIFFERENTIAL OMEGA STUDY OF APRIL 1969.

Abstract

The Omega navigation system accuracy of one to two miles can be improved significantly in a given area by obtaining sky-wave and propagation anomaly corrections from a fixed monitor in the area. The improvement in navigational accuracy is a function of the distance from the fixed monitor, the signal-to-noise ratio, and the instrumental accuracy of the receiving equipments. As part of the differential Omega study of April 1969, two AN/WRN-2(XN-1) Omega receivers were obtained, modified, and evaluated to determine the precision with which phase measurements could be made with this type of equipment. This report describes the modifications performed and the laboratory measurements made to determine the instrumental accuracy of the equipment used in the differential Omega study. (Author)
