Continuous observations using GPS were carried out on an ice sheet in East Antarctica, near Syowa Station for about 4 days to detect detailed movement of the ice sheet. It is possible to detect the short-time change of the location precisely by analyzing the differential GPS with data simultaneously acquired at a reference GPS continuous observation point, using precise ephemeris. We detected constant movement of the ice sheet toward the WNW of about 13 mm per day. The drift rate of the ice sheet movement coincides with the result of repeated differential GPS measurement over two years, so it is proved that the movement of the ice sheet is rather constant. This kind of GPS observation gives ground truth for geoscience.
