The world of satellite navigation is experiencing an era of expansion, as the GNSS community is growing. Besides the two already operational systems, the United States of America’s GPS and Russia’s GLONASS, two additional constellations are currently under development and near to be completed: the Chinese BeiDou and the European Galileo. Within 2020, four systems are then expected to be fully operational and will offer immense possibilities to improve navigation performance in terms of availability, continuity, reliability and accuracy. This chapter focuses on current and future GNSS, giving an introduction to each system and pointing out advantages and challenges of the multi-constellation scenario.
