The Internationalization of Radionavigation Systems

Rex A. Buddenberg

Abstract:	As the internationalization of radionaviation services proceeds, a standardization operating doctrine, signal characteristics and information transfer must occur. The needs of the international mariner and aviator require open systems standardization in several areas of the radionavi ation domain. Particularly with the advent of di 8 erential service, there is a prospect of many national and private service providers. The inteqration of satellite based and terrestrial systems is of known potential benefit. And the information transfer requirement associated with radionavigation systems is increasing. Loran and Omega provided only baseband timing information (plus a binary blink signal in Loran). GPS, in addition to the timing ,data provides a considerable information transfer in the almanac and ephemeris data broadcasts. Differential service takes this to an extreme -- all useful information is data transfer. Here there is no navigation intelligence in the baseband signal. This standardization effort in the radionavigation domain must be similar in scope to the one sponsored by the International Association of Lighthouse Authorities (IALA) for short range aids (buoyage) that has been in progress In the 1980s and is now virtually complete. The objective of this paper is to: 1 - frame the interoperability standardization problem and provide sufficient motivation, 2 - outline a suggested agenda, 3 - suggest some solutions in areas where some work can be adopted, not reinvented.
