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 receiverstation 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-airmaintenance 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.
