Traversing the South Pole: 14 days, 4 people and 750 kilometers

The video discusses a recent Antarctic expedition using piston bullies to support the ISAT-2 mission. The team conducted elevation measurements of the ice sheet using GPS and corner cube reflectors. They faced environmental challenges at the South Pole, such as high altitude and cold temperatures. The plan is to repeat the traverse over the next three years to gather comprehensive data for calibration and analysis, contributing to the mission's success.

What unique feature of the ISAT satellite was mentioned in relation to the elevation measurements?

What is the significance of repeating the traverse over the next three years?
