Abstract:

The differential Omega concept makes use of a control monitor to determine the difference between the received phase of the Omega signals and the computed or charted value. The difference noted by the control station, which is at a known location, is transmitted as a correction factor to the users in the field. This correction factor could also be based on a correction to the published sky-wave correction tables. Fixed monitors were established at this Laboratory in Washington, at the Chesapeake Bay Division at Chesapeake Beach, Maryland, and at the U. S. Coast Guard Electronic Engineering Center at Wildwood, New Jersey. The report is based on the data obtained at the start of the study. The results show that accuracies of one-half mile or better over a 24-hour period can be obtained at distances up to 100 miles from the control station. Author
