Omega System Performance Assessment

Abstract

A measure of system performance, termed the system availability index, is introduced as: (1) an indicator of operational performance, (2) a probability of system access and utility to the system subscriber, and (3) a means of comparing system options. Theoretical development of the index is given in terms of a system availability model which is based on receiver/station reliability, signal coverage, and user geographic priorities. Sample calculations of the index are presented to illustrate comparison of system options, e.g., the effect of a station off-air. Techniques are presented to compute a station power level assignment and station off-air/maintenance schedule. Comparison of signals from the VLF communications stations and the Omega system in terms of signal coverage, receiver utilization, and government policy is also given.
