A proposed differential Omega system
Goodman, Gill Reves
MetadataShow full item record
Omega is a long range electronic navigation system which utilizes phase difference measurements between signals received from two transmitting stations to determine a line of position. The major cause of inaccuracy in the system is the propagation anomalies of the Omega signals. Differential Omega is based on the theory that throughout a small geographical region the phase difference errors caused by these anomalies are identical. A monitor site might be established within this area which would determine the extent of the error and relay this information to other users. It is the purpose of this thesis to present and test a workable Differential Omega system which utilizes a Coast Guard radiobeacon as a monitor site and the modulated radiobeacon signal to transmit the correction information.
