Abstract:	In the near future, positioning signals broadcasted by US GPS, Russian GLONASS and European Galileo systems will be jointly used by Safety-of-Life enabled receivers in order to provide most continuous, safe and accurate positioning service. In addition to ranging codes and navigation data, the US WAAS, Japanese MSAS and European EGNOS will provide differential data for existing constellations and systems, augmenting accuracy performance above different regions over the globe. Lastly, the third generation of GPS as well as Galileo will provide users with global integrity monitoring systems and associated services worldwide. The perspective of having different integrity standards and augmentation systems standards converging between the different operators appears to be the optimum solution, in order to avoid extra costs in the development of interoperability for user equipment manufacturers and to enable the certification of positioning systems all over the world. In this frame, a global service providing standardized integrity data for the different constellations and systems would advantageously complement the coverage of regional area augmentation systems. The purpose of this paper is to analyze the different regional augmentation systems in parallel to the new integrity concepts that are being developed, to present their advantages and drawbacks and finally to evaluate the possible ways of convergence.
