Abstract In the calculation of ionosphere distribution, it is a key to eliminate the instrumental biases of satellite and receiver from GPS dualfrequency observations. The effects of changing sampling interval and VTEC fitting model were analyzed. The calculation results indicate that the 3hour sampling interval and cubic fitting model are sufficient for computing the instrumental biases on continuous GPS stations. \
