Invitation to media for Jason-2 pre-launch event

(PresseBox) (Darmstadt, ) We would like to invite you on Thursday, 5 July to our forthcoming media event - jointly organised with the French Space Agency (CNES) and Thales Alenia Space - in Cannes, France. Topic of the day is the Jason-2 space oceonagraphy mission. Experts from all three organisations will introduce you to the satellite and its main instrument, the Poseidon 3 radiometer; You will also hear about its benefits for the oceanographic user community and gain insights in some of the most sought for applications for operational oceanography.

This informative day will conclude with a visit to the clean room where you will see the satellite and the integration of its instruments before it will be shipped to Vandenberg, California - currently scheduled for April 2008.

Jason-2 is the response to an international initiative for ocean and climate study and observations to establish a global ocean observation system. The Jason-2 programme and Ocean Surface Topography Mission is built around a series of satellites that will take ocean altimetry to an operational level and collect global ocean surface data on a continuous basis for at least the next two decades. The Jason-2 satellite will deliver applications in the area of short and long term weather forecasting, operational oceanography, navigation and marine resource management, marine meteorology - and climate monitoring. A rise of global sea levels is widely recognized as potentially one of the more devastating consequences of global warming. Continuous measurements on a long term basis will help to analyse the mean sea level trend and its significance for global warming

Jason-2 is a Low Earth Orbit (LEO) satellite, flying at an altitude of around 1300 km. The main instruments on board are a radar altimeter (Poseidon-3), a microwave radiometer (AMR), and several precise orbit determination systems (Doris, GPS and laser retroreflector array). The aim is to measure the global sea surface height to an accuracy of a few cm every 10 days, determining ocean circulation, climate change and sea level rise. In addition to this core mission, three passenger instruments will measure the radiative environment at the Jason-2 altitude (Carmen 2 and LPT) and make high accuracy time measurements (T2L2).

Jason-2 is the continuation of the existing successful cooperation between the US and Europe, bringing together two operational and two research agencies (NASA and NOAA for the US, and CNES and EUMETSAT for Europe). The satellite was developed by the French Space agency CNES, with the contribution of the US agencies NASA and NOAA. It is based on the PROTEUS platform developed by Thales Alenia Space in partnership with CNES. Poseidon-3, the radar altimeter, was manufactured by Thales Alenia Space. Jason-2 is currently scheduled for launch in mid-2008, from the Vandenberg Space Centre in California, USA. Once launched, EUMETSAT will be responsible of part of the Ground Segment infrastructure, processing and distribution of operational data as well as interfacing with the operational users.


Die europäische Organisation für die Nutzung meteorologischer Satelliten ist eine zwischenstaatliche Organisation mit Sitz in Darmstadt, Deutschland, mit derzeit 21 europäischen Mitgliedsstaaten (Belgien, Dänemark, Deutschland, Finnland, Frankreich, Griechenland, Irland, Italien, Kroatien, Luxemburg, die Niederlande, Norwegen, Österreich, Portugal, Schweden, Schweiz, Slowakei, Slowenien, Spanien, Türkei und das Vereinigte Königreich) und 9 Kooperationsstaaten (Bulgarien, Estland, Island, Lettland, Litauen, Polen, Rumänien, Tschechische Republik und Ungarn).

EUMETSAT betreibt gegenwärtig die geostationären Satelliten Meteosat-8 und -9 über Europa und Afrika sowie Meteosat-6 und -7 über dem Indischen Ozean. Metop-A, Europas erster polarumlaufender Wettersatellit, wurde im Oktober 2006 gestartet und liefert seit dem 15. Mai 2007 operationelle Daten. Nach seinem Start, der für Mitte Juni 2008 geplant ist, wird der Jason-2-Meeresbeobachtungssatellit die bisherigen Missionen von EUMETSAT um Daten zur Meeresoberflächentopographie erweitern. Die Daten, Produkte und Dienste von den Satelliten von EUMETSAT leisten einen bedeutenden Beitrag für die Wettervorhersage und für die Überwachung des globalen Klimas.
