The success of previous ISU symposia suggests that the ISU has developed a unique and winning formula for a novel type of symposium. The characteristics of ISU symposia are that they: Adopt a broad, and interdisciplinary, perspective Address all aspects of the subject, ranging from policy, business, organisational, and legal issues to technical and scientific topics Foster a constructive dialogue among very different sectors of the space community, and Allow ample time for interactive discussions. The present Symposium is no exception. It considers the very timely topic of space-based systems for global positioning and navigation, ranging from the GPS system developed by the US military to the Russian GLONASS system, and on to the future European Galileo system. Other nations are planning regional augmentation systems.A Brief Summary of Four Keynote Addresses.- Galileo: Status and Way Forward.- At the Crossroads: Civil and Security Issues Concerning Navigation Satellites in Japan.- The Future of the GPS Local Area Augmentation System (LAAS).- Complement and Augmentation of GPS from a Quasi-Zenith Orbit.- A GNSS Literature Review and a Navigation System for Future Space Vehicles.- Galileo System Architecture  Status and Concepts.- Europes Challenges in Developing its Own Satellite Navigation System.- Cislunar Navigation.- Compatibility and Interoperability of GPS and Galileo: A Continuum of Time, Geodesy, and Signal Structure Options for Civil GNSS Services.- Galileo  The Essentials of InterlÓ:
