description Overview

TOPEX/Poseidon

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 oceanographers and climate scientists until it was decommissioned in 2006.

Jason-1

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 altimeter to precisely measure global sea level, wave heights, and ocean circulation patterns. The missio...
