Abstract The current development of IGSRTPP (International GNSS Service Realtime Pilot Project), its realtime products and data recovery are introduced. The realtime precise products from BKG (Bundesamt für Kartographie und Geodsie), ESA (European Space Agency), GFZ (Geo Forschungs Zentrum) and GMV(Guillermo Tobías González), which are IGS realtime analysis centers, are chosen and analyzed. Taking the IGS final products as a reference, the orbit can reach cmlevel accuracy while the clock offset subnanosecondlevel accuracy. The realtime orbit and clock products are taken as the input files of PANDA to do kinematic PPP(Precise Point Positioning) process at ALBH station with the results showing that the kinematic PPP process can achieve cmlevel accuracy in both horizontal and vertical direction.
Key words ：
