This report outlines the testing conducted at the National Aviation Facilities Experimental Center NAFEC in order to determine the critical characteristics of one airborne feasibility model Differential Omega System. Through static testing, dynamic simulation, and actual test flights in the Atlantic City, New Jersey area, Differential Omega was compared to Skywave-corrected and Uncorrected Omega. These experiments provided data to determine the operating range, accuracy, the limits of system performance, and an accuracy comparison using three different phase correction techniques. It was found that Differential Omega was the most accurate system with no noticeable decrease in accuracy up to 150 nautical miles. This analysis outlines further improvements to the Differential Omega system which may be incorporated into later units to improve their capability. Author
