Abstract:

The document develops estimates for navigational fix accuracy to be expected when the signals of the Omega VLF Navigation System are used in the relative mode, under which circumstances the system is known as Relative Omega. Improved accuracy over that for standard Omega results because of the correlation of long-path signal phase variation as observed over a several-hundred-mile area. Results are developed from previous work on the expected accuracy of Differential Omega but modified to demonstrate the application to Relative Omega. Specifically, results are addressed to the use of ANSRN-12 Omega receivers, as envisioned for a portion of the integrated navigation system to be used on DD 963-class Naval vessels. Effects of instrumentation, propagation, and geometry are considered. Modified author abstract
