  • Method for frequency cross-coupling of channels in an Omega Navigation receiver system
    Patent number: 3996515
    Abstract: This invention relates generally to radio navigation receivers and particularly to multiple frequency phase tracking receivers in which phase information received from a network of transmitters, each radiating coherent signal energy on a plurality of discrete frequencies, is used for navigation or position determination. There is provided a method of updating positional information derived from the plurality of discrete frequency signals by cross-coupling the input to each of the discrete frequency receivers so as to reduce the lag time between receiving two sequential one-frequency signals and updating the signal.
