Abstract
In high precision GPS data processing ,domestic and the surrounding IGS sta-tions measurement is necessary for the introduction of ITRF frame .The quality of IGS sites directly determine the quality of baseline processing ,so it is necessary to evaluate the quality of the IGS sites .After checking the quality of the IGS sites in China and the nearby IGS site by using TEQC ,It is detected that URUM station L2 phase carrier lost from 2013 186 to 218 days .Lots of days of WUHN station which observation duration is less than 2 hours .Some days of LHAZ have some problems such as low efficiency .After the quality analysis of IGS sites ,effective use of these sites becomes easy .关键词
