Abstract Realtime dynamic displacement of the stations was obtained by using trackRT realtime positioning module to process continuous GPS data, the horizontal accuracy is about 1 cm, vertical accuracy is about 2 cm; trackRTr was also used to process 1 Hz GPS data of 2011 Japan Mw9. 0 earthquake to simulate realtime processing and a comparison with postprocessing was made; the impact of ephemeris and baseline length on accuracy was also analyzed, the results show that the baseline length plays a important role on the calculation accuracy.
Key words :
trackRT
real-time GPS processing
kinematic deformation
orbit satellite ephemeris
