Swarm FAST data ready to be released

30 Oct 2023

We are pleased to announce that the development of FAST data (“NRT”) parallel chain has been recently completed and the Transfer-To-Operation (TTO) of the first FAST processor will be performed on 2 November 2023. This processor aims at producing Swarm L1B FAST data as soon as the Swarm telemetry data are made available.

You can find the FAST data on the ESA Swarm dissemination server from 2 November onwards:

  • Via any HTTP browser at
  • Directly via an ftp client at

Please note that the FAST data will be generated with the most updated version of L1B data processing algorithm, i.e., the same used to generate the Swarm OPER L1B data.

If you spot any issues in accessing such data or during the analysis of these data, please do not hesitate to contact us via
