The number of civilian applications has exploded in recent years and its popularity is undisputed. Other GNSS have had issues (GLONASS during the end of the 90s and the 00s) or are still incomplete (Galileo, BeiDou). This helps explain the fact that a large percentage of the population is familiar with the term “G

It’s true that it does not easily spring to mind that the images captured by Earth observation satellites, nowadays with submetric spatial resolution at best, can produce displacement measurements with a precision measured in centimetres or millimetres, as the experts claim. But what exactly d
