[Sentinel-3B] Already starting Calval activities on all instruments

Thu, 2018-05-17 00:56
The second Copernicus Sentinel-3 satellite, Sentinel-3B, lifted off on a Rockot from the Plesetsk Cosmodrome in northern Russia at 17:57 GMT (19:57 CEST) on 25 April 2018. It will join its twin Sentinel-3A, in orbit since 2016, for a tandem phase of four months which will start at the beginning of June. Both Sentinels will fly just 223 km apart, which means that Sentinel-3B will be a mere 30 seconds behind Sentinel-3A. After this, Sentinel-3B will be moved apart on the same orbit to a wider separation (140°). Both ESA-developed Copernicus satellites carry four Earth-observing instruments to measure oceans, land, ice and atmosphere:
  • Ocean and Land Colour Instrument (OLCI),
  • Sea and Land Surface Temperature Radiometer (SLSTR), 
  • SAR Radar Altimeter (SRAL), 
  • MicroWave Radiometer (MWR), 
and instruments fo Precise Orbit Determination (POD) including:
  • DORIS receiver (Doppler Orbitography and Radiopositioning Integrated by Satellite)
  • GNSS receiver (Global Navigation Satellite System)
  • LRR (Laser Retro Reflector)
All instruments have been progressively switched on, in particular :
DORIS on May 1st at 10:30:00 UTC
MWR (radiometer) on May 7th at  09:48:00 UTC
SRAL (altimeter) on May 8th at 06:02:05 UTC CalVal activites are already ongoing with a strong implication of CNES, CLS and Noveltis team.

September 2018 : CALL FOR ABSTRACTS for annual meeting of the Ocean Surface Topography Science Team (OSTST)

Fri, 2018-04-20 02:50
The annual meeting of the Ocean Surface Topography Science Team (OSTST), will be held in the second part of the "25 Years of Progress in Radar Altimetry" Symposium and will address specific issues on the TOPEX/Poseidon-Jason series of missions, including algorithm and model improvement, Cal/Val activities, merging with other altimetric satellites (CryoSat-2, SARAL/AltiKa, HY-2, Sentinel-3), and preparation for the Sentinel-6/Jason-CS and SWOT missions.   Because of the obvious relationship with the Symposium, it is proposed that the purely science presentations of the OSTST PIs and Co-Is be given in the Symposium. This will leave more time during OSTST for specific splinters, technical presentations, including a poster session. The International Doris Service (IDS) workshop (1.5 days) will take place in parallel to the "25 Years of Progress in Radar Altimetry" Symposium and start after the Monday morning plenary session. Abstracts submission for the OSTST and IDS meetings is open through this interface  and will end on May 14 (midnight UTC).   For OSTST, splinters descriptions to choose where to submit your abstract can be found here.
