Abstract : The feasibility of OMEGA as a world-wide backup navigation system for high speed, high altitude aircraft has been demonstrated. At most, minimum rate aiding from external sensors is required when OMEGA is employed under cruise vehicle dynamics. The generally predicted accuracy of 1 to 2 NM is considered conservative in view of the probability of future refinement of propagation prediction based on empirical data. Current problems resulting from poor geometry, interference, weak signal and resulting low signal-to-noise ratio will become academic with the implementation of the full power transmitter network by the end of 1973. Equipment is highly reliable, simple to operate and lends itself well to interface with other systems and the assumption of related tasks. Interference problems do not appear serious at this time. A continued effort is in order to further refine equipment and exploit such additional applications as Differential, Inertial and Retransmitted OMEGA. Full utilization of the global reconnaissance mission and environment should be exercised to permit timely and cost effective achievement of this goal. (Author)
