Abstract : Omega is a long-range, very-low-frequency, hyperbolic radio navigation system. Coverage for the entire earth will be provided by eight transmitters which transmit on the same frequencies on a time-sharing schedule. Each station transmits for approximately one second on 10.2 kilohertz (kHz), one second on 13.6 kHz, and one second on 11-1/3 kHz in a sequence such that only one transmitter is transmitting on a particular frequency at any given time. The sequence repeats every ten seconds. The field intensity measurement of an Omega transmission is difficult to make due to the low-duty cycle of the transmission and to the high atmospheric noise level. A system for measuring the field intensity of Omega signals was developed using a Tracor Omega receiver, M DEL %((R, and a calibrated loop antenna, the details of which are given in this report.
