Many of the satellites that gather information on the health of our planet pass over the polar regions pass above the North and South Poles. Satellite ground stations located in these remote areas are best positioned to collect the data and talk to the missions passing above them. This video presents the most northern ground station ESA is using – SvalSat, located within the Arctic Circle – where contact is made with many of ESA’s Earth observation missions. The Svalsat station contributes to ESA's global tracking station network, Estrack.
