Fugro is operating a global GNSS infrastructure for the delivery of high-accuracy multi-constellation Precise Point Positioning (PPP) service, named G4. Precise orbit and clock for all global satellite navigation systems are estimated in real-time and broadcast to the users using geostationary satellites. End-users with a G4-enabled receiver are able to obtain sub-decimeter positioning accuracy in real-time. The system has been tailored for offshore applications where a nearby GNSS station is not always readily available. G4 offers seamless integration of GPS, GLONASS, Galileo and BeiDou in the navigation solution, therefore allowing the user to obtain a reliable and accurate position even in challenging environments, especially in presence of interference, scintillation or partial sky visibility. In addition, carrier-phase integer-ambiguity resolution (IAR) is supported, for those users requiring the highest possible navigation accuracy. This paper presents the G4 system architecture and current performance. The benefits of multi-constellation Precise Point Positioning (PPP) are shown in terms of increased availability, robustness and accuracy.
