Abstract The multipath error and the ionospheric delay are used as the evaluation indicators to analyze the GPS data of Amery Ice Shelf ,ice sheet, Nella fjord, Larsemann Hills and some IGS stations in Antarctic. The following conclusions can be drawn.1)At the same site, the multipath error of L2 is always larger than L1.2)Multipath error differs from each other according to the different circumstances in Antarctic area.3)Different latitudes and intensity of solar activity are the two main factors which influence the ionospheric delay.
Key words ：
