Best regards, Pascale Ferrage ------------------------------------------------------------------------------------------------ De : Guinle Thierry Envoyé : jeudi 12 septembre 2013 17:39 Objet : [Jason-2] : Status update - Restart of core mission Dear OSTST, The Jason-2 satellite is again operational. Today at 12:22 UT, the POSEIDON3 altimeter has been switched ON; 2 hours after, AMR radiometer and precise GPS were also enabled (around 14:17 UT and 14:21 UT respectivelly) allowing the mission to restart nominally . - NRT production (OGDR) has already restarted and the products should be distributed by EUMETSAT and NOAA in the coming hours. - Off line products (IGDRs) will be produced with some delays (after CALVAL quality checks). The routine production should resume nominally next week. The Jason-2 mission was interrupted since cycle 190 pass 185. Normal science operations will resume at cycle191 . Jason-2 passengers will be switched on next Monday (September 16th) Many thanks to the CNES and NOAA Ops teams for this quick and efficient recovery. Very best regards, Thierry Guinle - CNES on behalf EUMETSAT-NOAA-CNES-JPL Project Managers _______________________________________________________________________________ De : Guinle Thierry Envoyé : jeudi 5 septembre 2013 17:59 À : ostst Cc : Guinle Thierry; L-SALP_astreinte Objet : Jason-2 in Safe Hold Mode since 05 September 2013 03:31 UT Dear OSTST Members, The Jason-2 spacecraft entered safe mode on 05 September 2013 at 09:26 UT, immediately interrupting its measurements during Cycle 190. The satellite is currently in a safe and stable Sun-pointing configuration. Expert teams from CNES and industry (TAS) have been activated and the first investigations have started today. It seems (to be confirmed) that a memory error is the root cause of the reconfiguration. The 4 partners operational teams are working closely to support current and future operations. The mission will resume as soon as possible, and we will keep you informed of our progress. Very best regards. Thierry Guinle of behalf of Jason-2 project managers from NOAA, EUMETSAT, JPL and CNES Cliquez sur l'url suivante https://www.mailcontrol.com/sr/bODAXcIXRdDGX2PQPOmvUv46NwAC7+vkhXMw5hPfpL6g6SHDMQAX0lp7j3JRijX99pvysTSTyGDLq66BGWNXYg== si ce message est indésirable (pourriel).
