TOPEX/Poseidon was a joint satellite mission between NASA and the French space agency CNES, launched in 1992 to measure global sea-surface topography. Using dual-frequency radar altimeters, it accurately mapped ocean currents and tracked changes in sea level. The satellite provided critical data for...
Jason-1 was a joint ocean altimetry satellite mission developed by NASA and the French space agency CNES. Launched on December 7, 2001, it served as the direct successor to the highly successful TOPEX/Poseidon satellite. From an orbit approximately 1,336 kilometers above Earth, it used a radar altim...
Jason-2 was an international satellite altimetry mission launched on June 20, 2008, through a collaboration between NASA, CNES, EUMETSAT, and NOAA. Positioned in low Earth orbit, its primary objective was to measure global sea-surface height and continue the critical climate data record initiated by...
Jason-3 is an Earth observation satellite designed specifically to monitor global ocean surface topography and sea-level rise. Launched on January 17, 2016, it represents an ongoing international collaboration between NASA, the French space agency CNES, NOAA, and EUMETSAT. The spacecraft utilizes a...
Sentinel-6 Michael Freilich is an Earth observation satellite developed jointly by NASA, ESA, EUMETSAT, and NOAA to measure global sea levels. Launched in November 2020, the mission continues a decades-long record of precision ocean altimetry that began in 1992 with the TOPEX/Poseidon satellite. The...
