Galileo-GPS Interoperability And Compatibility: A Synergetic Viewpoint

R. Dellago, E. Detoma, F. Luongo

Abstract:	Various definitions have been proposed for the terms "compatibility" and "interoperability". Generally, or at least within the context of this paper, compatibility addresses user equipment issues, while interoperability is to be intended more at the system level. This point has been the subject of a hot debate in Europe concerning the establishment of a Global European Satellite Navigation System (GNSS-2 or Galileo) and its relationship with existing systems, namely GPS and Glonass. For a system to be interoperable, some commonalties must exist; for interoperability to be profitable these commonalties shall be carefully analyzed to lead to a system architecture in which both systems (an existing one and a proposed one) can achieve maximum benefits. This is particularly important when of the two systems under considerations one is already in existence and the other is being developed now. The use of a common format, standard formulae and parameters will simplify worldwide navigation and time dissemination by GPS, Glonass and the future European navigation system, Galileo.
