Differential Omega is a navigation system based upon the real-time dissemination of Omega corrections for an area around a monitor site at a known location. This investigation of its potential for meeting Navy navigational requirements in the U.S. coastal confluence region, where traffic patterns tend to converge, finds that a system of 29 base stations - only one of them new - would provide CCR coverage with cross-track accuracy of about 1/4 nmi. Station spacing proposed for the Gulf of Mexico provides accuracy of 1/4 nmi or better throughout the fairway area. Comments on signal format are solicited from all interested parties. The Navy is presently shifting differential Omega work from exploratory development to advanced development and hopes to construct a prototype beginning in FY75.
