The Sentinel-3 mission is now operating for over 3 years. During this time the altimeter processing chain has been updated regularly as the result of fixing anomalies, enhancing performance, or reacting to user feedback. Lessons learned from this experience are used for the development of the Sentinel-6/Jason-CS ground segment and product evolution plans.

This poster gives an overview of the products available for both missions, their intended use, and the way user feedback drives evolutions of the processing chain and how the consistency of the radar altimeter data from those missions is guaranteed through annual reprocessing.

The Sentinel-6 mission will start with the launch of Jason-CS A in 2020, followed by Jason-CS B in 2025.
