  • In precise GPS data processing,absolute antenna phase center correction model has much advantage with relative model. When using different antenna phase center correction model,it has impact on GPS results. After analyzing the results of a city's CORS GPS data processed by Bernese GPS software,we find that coordinate in height various at a cm level,net scale factor changed 6.4 ppb,difference of troposphere ZPD value is -6.9±4.0 mm.
