The Precise Point Positioning (PPP) technique has been intensively developed in the GNSS community for the last decade. The technique makes use of precise orbit and clock corrections to perform precise positioning for a single receiver. However, the traditional PPP technique does not fix carrier-phase ambiguities to their integers because satellite hardware biases are not eliminated when using data from a single receiver. Additional corrections are needed to form and fix integer ambiguities, and consequently improve the accuracy of positioning. In March 2015 Fugro introduced the G2+ (or G2 Plus) service that provides hardware-bias-like corrections together with orbit and clock corrections for GPS and GLONASS systems. All these corrections are computed in real-time and broadcasted globally to our clients in the field via L-band communication satellites. This paper describes the technology that Fugro has developed and presents some results obtained using the service.
