The paper affirms the fact that satellite navigation is an aid to ocean surveying. The potentials in using the Navy Navigation Satellite System are developed to show that it does not duplicate the service rendered by any other navigation system such as OMEGA. It, in fact, complements those systems. It is also shown that satellite systems extend the range and accuracy of land based systems. The paper discusses three satellite navigation methods Doppler, Visual, and Ranging. In each case capabilities and limitations of the methods and prototype, or operational equipment are discussed. Examples are given of recent results from transponder surveys which themselves in deep ocean areas can attain relative accuracies of 20 to 25 yards and are made possible through the use of the Navy Navigation Satellite System. A practical method of determining the accuracy of one satellite fix at sea under average operational conditions is also discussed. Finally, the Translocation Method and the Interrogation, Recording and Location Subsystem are described briefly under developmental systems. Author
