摘要：

This paper summarized the on-orbit measurement performance of GLAS, and analyzed the precision of its data products. By comparing the high-accuracy ICE Sat measurements with the GPS ground surveys during 21st CHINARE inner ice sheet s expedition, it is analyzed and validated that the suggested Dome A area and the measured peak point of Antarctica inner ice sheets defined during 21st CHINARE are both correct.
