A Concept for the European Contribution to the Civil Global Navigation Satellite System

M. Wlaka

Abstract:	The outstanding importance of satellite navigation for all kinds of future traffic management and other matters of public and private life, is recognised world-wide. Market analysists forecast a rapidly growing equipment and ser- vice market. Therefore it is understandable that the USA wish to make the best economical use of their investment in GPS. A strong argument for USA control of GPS is the guarantee of national security. The same applies to Russia with respect to GLONASS. On the other hand other nations are reluctant to base their future trafftc management infrastructure on a foreign military controlled system. Therefore a world-wide de- mand for a civil satellite navigation system has been expressed, a system under civil control, well matched to needs of civil users. For Europe a civil navigation system, called ENSS has been proposed, which could possibly be the European contribution to the civil global satellite navigation system GNSS-2. The ENSS will provide an autonomous naviga- tion service for Europe, superior to GPS / GLONASS, for all modes of transportation and other applications. On the other hand the system will be backward compatible to the European Geostationary Navigation Overlay Service EGNOS, currently under construction. The utilisation of GPS / GLONASS and ENSS will result in a very robust system with excellent availability. By means of generic diversity, i.e. one satellite system can serve as a back-up to another in case of systematic failure, even the most strigent requirements of ICAO or FAA respectively JAA with respect to integrity, availability and continuity will be met. In order to build up the GNSS-2, it would be advan- tageous to harmonise the work of other nations, such as Japan, Indonesia, Australia etc., to establish regional satellite navigation systems. Internationally agreed standards would guarantee a world-wide seamless civil navigation service, being composed of regional elements.
