Omega is a long-range, very-low-frequency radionavigation system with capabilities of providing a fix with an uncertainty of one mile or less at ranges of 5000 miles from the transmitting stations. The variations in propagation velocities of the signals over a particular path are the major cause of the errors. If the system is used as a rendezvous aigy the propagation errors will cancel out. Thus, the rendezvous accuracy will be greater than the absolute accuracy. The object of this investigation was to determine the rendezvous accuracy of a helicopter and a truck in various surroundings by use of Omega. The forestport-summit transmissions demonstrate that the system could be used as a rendezvous aid with accuracies of around 200 yards, with the time of day or environment having no apparent effect on the rendezvous errors.
