Evaluation of a Commercial OMEGA Navigation System Installed in the C-118 Aircraft.
Abstract
A Commercial OMEGA Navigation System (ONS) Litton LTN 201, was flight tested to determine the suitability of the system to meet the commercial specifications and the Navy's long-range overwater navigation requirements for the C-118 aircraft. The ONS on the C-118 aircraft had a position error of less than 1 nautical mile (commercial spec error no greater than 7 nautical miles) for the three areas of operation, CONUS, Caribbean and Mediterranean. Signal to noise ratio readings indicate six stations were available for navigation at all times. Seven stations are the maximum number of stations which can be used for navigation due to algorithms in the LTN 201. In the Mediterranean area, seven stations were available for navigation in 85% of the samples taken. No point estimates can be made on the reliability of the ONS. With approximately 150 flight hours, there were no failures. A Commercial OMEGA Navigation System will satisfy the long-range overwater navigation requirement in the Atlantic, Caribbean, and Mediterranean for the C-118 aircraft. (Author)
