2008-08-25 SSALTO/DUACS products unavailable since 2008/08/21

The recent Jason-1 safehold mode induced a data gap in the Jason-1 altimeter data series and this gap is larger than the one allowed by the resilience of the DUACS system.

The production is scheduled to be resumed this night.

- 2008/08/20 : Jason-1 mass memory has been reconfigured and the payload has been switched on.
