A network augmented real-time precise point positioning algorithm called NAPPP was proposed.The new algorithm process data of user station together with some other nearby reference stations,and estimate position of user station,satellite position and clock corrections on-the-fly based on the real-time accessible broadcast ephemeris.The NAPPP software was developed and experiments were carried out based on the network composed of 5 IGS stations from European area.The results support that the positioning accuracy of NAPPP is about 1-2 cm and 2-6 cm respectively for static and kinematic positioning.Both positioning performance and convergence time are far better than PPP result with IGS final orbit and 30 s clocks,and comparable with PPP result with final orbit and 5 s clocks of CODE.
