Abstract : The concept of composite Omega, as developed by J. A. Pierce, is shown to be equivalent to a statistical optimization of the information available from two Omega carrier frequencies. However, composite Omega offers no increased stability over that available from the 13.6-kHz carrier except over arctic paths during disturbed conditions. From a statistical standpoint, conventional lane resolution of the 10.2-kHz carrier lanes from 3.4-kHz difference frequency measurements is a virtual certainty except during disturbed conditions.
