%X On the basis of the ionospheric grid-correction data which are tested by wide-area precise real-time positioning system.The ionospheric delay of the signal puncture point over the reference station is estimated by using two weighting methods.Futher more the estimated ionospheric grid delay of the signal puncture point has been compared with those tested in the actual measurement.For the stations located in different positions,in the middle or high-latitude the grid correction is better than that in low-lati...
