英文摘要	We collected kinematic Global Navigation Satellite Systems (GNSS) surface height data, on a 750-km ground-based traverse of the flat interior of the Antarctic ice sheet, for comparison with Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) surface heights. Vertical errors in the GNSS data are estimated to be 5.6 cm, comparable to results from a previous traverse and with year-to-year comparisons. Comparisons of the GNSS heights and 6 months of ICESat-2 ATL03 photon-based heights and ATL06 segment-based heights indicate that the accuracy and precision of ICESat-2 data are comparable to that of results from the ICESat mission: ATL03 is currently accurate to better than 5 cm with better than 13 cm of surface measurement precision, while ATL06 is currently accurate to better than 3 cm with better than 9 cm of surface measurement precision.
