Abstract: According to the requirements of high precision satellite navigation and ionosphere activity monitoring,double-frequency measurement data from 238IGS stations are used to calculate vertical ionosphere electron content（VTEC）,DCB of GPS,GLONASS and the corresponding receiver based on the spherical harmonic function model.The results show that this implemented model is reliable.The DCB precision of GPS and GLONASS obtained is less than 0.1ns when compared with the results of CODE and less than 0.2ns when compared with that of IGS.The DCB precision of GPS and GLONASS receivers are less than that 2ns,while the precision of VTEC is better than 3TECU in comparison with that of CODE and IGS,and better than before combination.
