First data from the Copernicus Sentinel-6 satellite: new data exceeded all expectations

Scientists receive first data from Copernicus Sentinel-6 satellite

Three weeks ago, the Copernicus Sentinel-6 Michael Freilich satellite was launched into space. It has already provided the first data of the observations, and their results surprised the scientists. The satellite is equipped with exceptional altimetry technology due to that it transmits very accurate data on the sea level. Copernicus Sentinel-6 Michael Freilich was launched into orbit on November 21.

The first signal was recorded by the ESA operations center in Germany. The satellite is equipped with a state-of-the-art radar system that can expand long-term recordings of sea-height measurements.


The scientists have been receiving this data from satellites since the 90s of the last century. Analyzing the first information received from the new satellite, the specialists were surprised by the quality and accuracy of all measurements.

The satellite overlaid all data on sea level anomalies on a map that demonstrates the results of previously conducted similar missions. They used the satellite systems Jason-3, Sentinel-3A and Sentinel-3B. Each new image compares the previous data.

All images are independently processed on board the satellite, analyzing all the available information for a specific area. By removing the trailing edge of data before transmission to the Earth, the data rate is reduced by 50%.


The data called incredible, the satellite transmits due to digital architecture and processing by high-resolution synthetic aperture radars and traditional low-resolution mode. This method is used for the first time.

ESA Earth Observation Program Director Josef Aschbacher noted that the experts were surprised by the high rates of data transmitted by the satellite. Based on the information received, all predictions made will be more accurate.
