The spacecraft will be launched into a non-Sun-synchronous orbit with an inclination of 66 degrees with an orbital period of 112 minutes and 26 seconds. This orbit was chosen because it is the same as previous sea level missions (the TOPEX/Poseidon, Jason-1, OSTM/Jason-2, and Jason-3 satellites) to ensure data consistency for long-term sea level time series. Like its predecessors, Sentinel-6 Michael Freilich's non-Sun-synchronous orbit was chosen to allow the spacecraft to pass over locations at different times of the day and night, allowing it to measure local sea level changes that may vary throughout the 24-hour cycle, like the tides.
Satellite antennas located in Kiruna (Sweden) and Fairbanks (U.S.) are the ground stations that will provide X- and S-band communications with the Sentinel-6 Michael Freilich spacecraft. The Kiruna ground station coverage is provided by EUMETSAT; the Fairbanks ground station coverage is provided by NOAA.
