Jason-3 in the starting blocks
Jason-3 will continue providing high-precision ocean topography measurements in line with its predecessors, Jason-1 and Jason-2. Jason-3 will be positioned in the same orbit as Jason-2 (still in operation), at an altitude of 1,336 km, with an inclination of 66°. This highly inclined position will allow it to monitor some 95% of ice-free ocean surfaces every ten days. It will weigh 553 kg at launch, and offers 550 W of electrical power.
Another operational oceanographic satellite built by Thales Alenia Space, Sentinel-3A, is now being prepared for a launch planned in the coming weeks, from the Plesetsk Space Center in Russia.
