The ESA system includes internet connectivity (1.2Gbps access shared by all sites) with a fully redundant design, secured access through firewalls and denial-of-service protection.
The European Space Agency (ESA) is using an IP wide area network (Wan) from Interoute to link up its 13 sites with bandwidth of between 1.5Mbps and 500Mbps. EAS will enable it to store and secure valuable environmental satellite data.
“An efficient and secure distribution network with very large bandwidth is essential to effectively gather, archive and distribute the large amount of data from the European satellite missions related to Earth observation, to co-ordinate around ground facilities throughout Europe and co-operate with most European ground-segment operators,” said Eugenia Forcada-Arregui, head of the EOP Ground Segment Strategy Management Office at the ESA.
This picture gallery shows examples of the satellite images stored and secured on the network. See, for example, the Icelandic volcano ash cloud that is causing the airline industry such trouble (picture 2) as well as the devastating oil splill in the Gulf of Mexico (picture 7).
