Abstract: This invention is a system for teaching the principles of Omega navigation and the operation of Omega receivers, which system comprises a simulation computer that provides to an Omega interface (which acts as an Omega receiver) the appropriate Omega signals to simultaneously represent a plurality of Omega transmitters, and an on-board computer that is stimulated by the formatted output of the Omega interface. A student may enter the location of his vehicle into the on-board computer and observe the positional change of his vehicle as the Omega interface receiver is updated with simulated Omega transmissions.
