Abstract:GPS data from 2004 to 2012 of continuous stations of Fujian GPS Observation Network were examined using TEQC software,and annual statistics report of MP1、MP2 and CSR for every station were organized.The comparison of IGS standard with field survey indicates:1)The MP1 and MP2 value of the stations established in earlier period was stable,some CSR values changed violently because of the lightning strikes,covering of the surrounding trees and electromagnetic interference within 100 meters.2)Anticycle slips ability of the new GPS receivers are better then the old.3)90% of the 30 stations new established are better than the IGS standard.The covering of surrounding trees leads to the index higher than the standard.
