A degradation of attitude data for all Swarm satellites has been identified in the L1B data generated during STR operations at 2 Hz sampling rate, i.e. since 17 October, 12 December 2018 and 18 December 2018 for Bravo, Alpha and Charlie respectively.

The problem is due to an issue in the Swarm L1B data processing chain. A re-generation of the impacted data is therefore needed and will be performed as soon as possible.

More information concerning the re-generated data availability will be published soon.
