Abstract: Omega is reviewed from the vantage point of several years operational experience with the system in nearly final configuration. After identification of some possible shortcomings or deficiencies, system design parameters are re-examined with a view to determining possible investigations, modifications, or changes which might mitigate or lead to elimination of difficulties. Potential coverage limitations are identified in several areas while a coverage deficiency in central North America is to be expected. Significant reception difficulties have been noted in aircraft. Specific recommendations are made for investigations leading to improved receiver design and to mitigate reception problems in aircraft. Despite system maturity, a considerable and perhaps surprising latitude exists for modifications. Methods are presented by which one or more additional stations can be added without obsoleting existing equipments. This paper is an abridgment of an 80-page report of the same title written with Mr. J. E. Britt and Mr. A. N. Smith. This paper is intended to draw attention to, rather than substitute for, the longer work. A particular loss due to brevity is an adequate expression of appreciation to the many individuals who contributed advice or suggestions to the parent work and who are not individually acknowledged herein.
