Abstract: Considering the particularity of ionosphere over China and scattered GPS stations in the west, ionospheric refraction correction technologies was explored to provide accuracy data for the single-frequency users of the navigation positioning and remote sensing systems based on satellite. Employing variogram and ordinary Kriging as main tool, this paper elaborated the main idea of ordinary Kriging ionospheric delay correction. Exponential model that is possibly close to the experiment variogram was established respectively considering the quiet and stormy cases. This paper discussed in detail the precision of SBAS ionosphere correction for China region using dual GPS data from Chinese crust deformation monitoring net. Also, result from Kriging is compared with that from planar distance interpolation. The relevant results reveal that Kriging method can improve the accuracy of ionosphere correction and guarantee the integrity of system especially for scattered sample in the cover region.
