Abstract:

It is important to both monitor and predict the behaviors and evolutionary trends of ice sheets in relation
to future changes of climate and sea level. Geophysics has particular importance in scientific polar exploration,
and the unique advantages provided by airborne geophysical surveys make it an active and promising
field of research. China has become the fourth country with a polar airborne geophysical platform, and
it has surveyed thousands of square kilometers area of Princess Elizabeth Land, East Antarctica. The objective
of this study was to undertake post-processing of GPS data, and to evaluate the accuracy of precise point
positioning through comparison experiments. Based on the results of the experiments, we developed software
for matching and linking GPS and geophysical data. Then, we summarized a workflow procedure for
GPS data processing and we formulated a practical scheme for the post-processing of GPS data acquired
during a polar airborne geophysical expedition. The findings of this study can be considered a guiding reference
for future related work.

Key words: airborne geophysical survey, GPS, data post-processing, precise point positioning, match, joint
