The geolocation accuracy per spectral band (expressed as Absolute Location Error, ALE) from 2014 onwards can be viewed here.
Note that during the first months of the PROBA-V operations, the ALE was relatively high (peak values ~150 – 250 m) due to a star tracker issue. After this issue was solved, the ALE became much lower and was generally well below 100 m. When ALE values are considered too high for more than ~5 days, the geometric ICP is updated to ensure better geolocation performance. However, during the last two years the geolocation has been stable and no IC file updates have been necessary since 8/9/2016. The very high values for 19 – 21/9/2018 are currently being investigated, see for more information the ‘Known Issues’ section.
