Minimize Sentinel-6 Mission

The main purpose of the SENTINEL-6 mission will provide long-term continuity of the satellite altimetry measurement (sea surface height) from the TOPEX/POSEIDON, JASON-1, JASON-2, and JASON-3 missions and to extend the climate data record whilst improving measurement precision and accuracy.


The SENTINEL-6 Mission Guide provides a high-level description of the mission objectives; satellite description, including payloads, orbit characteristics, coverage and data products. It also covers an introduction to heritage missions.


The mission is being developed by a multi-agency partnership comprising ESA, EU, EUMETSAT, NASA-JPL, NOAA and CNES. ESA is responsible for the SENTINEL-6 (JASON-CS) space segment development with Airbus Space and Defence GmbH as a prime contractor.


This Mision Guide provides imformation on the following areas:


  • Overview

This section gives a brief description of the spacecraft, including its payload, the heritage missions (TOPEX/POSEIDON and JASON missions), the main improvements compared to previous altimeters, the main thematic areas and services (e.g. ocean, land) and a summary of the complete mission details. It also provides information about the different agencies involved in the mission.


  • Mission Objectives

This section describes the primary and secondary objectives of the SENTINEL-6 mission.


  • Satellite Orbit and geographical coverage

This section describes orbit characteristics and the geographical coverage.


  • Ground Segment

This section describes the Sentinel Core Ground Segment and its main facilities.


  • Instrumental Payload

This section describes the main instruments of the SENTINEL-6 mission: Synthetic Aperture Radar Altimeter (POSEIDON-4), MicroWave Radiometer (AMR-C) and Precise Orbit Determination (POD) instruments (DORIS and GNSS-POD) and the secondary GNSS-RO for radio occultation instrument.
