Swot orbit changed for the "science" orbit
2023-08-02Between 10 and 20 July, Cnes teams performed a series of manoeuvres to raise Swot satellite's altitude by 33 km. The satellite has been in a calibration and validation 1 day orbit for 6 months. The aim of the orbit change is to transfer it to its final "science" 21 day-orbit, at an altitude of 891 kilometers.

Monitoring of the Kakhovka reservoir/river by altimetry
2023-06-22The Hydroweb database – https://hydroweb.theia-land.fr/ – is monitoring changes in water levels over time on large lakes, reservoirs and rivers, from altimetry measurements. Hydroweb was not originally designed to monitor the degradation of reservoirs, either naturally or as a result of destruction, such as at the Kakhovka dam on the Dniepr river. Although it did provide relevant and accurate information on the evolution of the reservoir in the days following its recent explosion. These ...
