GMES Sentinel-1 mission

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008

The ESA Sentinels constitute the first series of operational satellites responding to the Earth Observation needs of the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The GMES space component relies on existing and planned space assets as well as on new complementary developments by ESA. This paper describes the Sentinel-1 mission, an imaging synthetic aperture radar (SAR) satellite constellation at C-band. It provides an overview of the mission requirements, its applications and the preliminary technical concept for the system.

In Europe the development of space technology is being coordinated by the European Space Agency under tight control of its Member States and their normal democratic procedures. For mature Earth observation applications other than meteorology a new European programme framework for operational satellites is emerging, based on the explicit requirements of services provided to the end-user. The Global Monitoring for Environment and Security (GMES) programme is a joint initiative of the European Union (EU) and the European Space Agency (ESA). As part of the GMES space component, ESA is undertaking the development of a European Radar Observatory (Sentinel-1), a European polar orbiting satellite system for the continuation of SAR operational applications. Sentinel1 is an imaging radar mission at C-band aimed at providing continuity of data for user services. Special emphasis is placed on services identified in ESA’s GMES service elements (GSE) program. Additional inputs come from ongoing G...

In the frame of the Global Monitoring for Environment and Security programme (GMES) jointly implemented by ESA and EC, ESA is developing the Sentinel-2 system, providing globally with systematic acquisition high resolution (10-20 m) optical observations with a high revisit tailored towards the needs of operational land services. This system will ensure data continuity of SPOT and Landsat multi-spectral sensor series and further enhancement to account of future service evolution.

Keywords: Earth observation monitoring environment satellite Sentinels services atmosphere ocean land emergency response climate change security user requirements data products data policy Global Monitoring for Environment and Security (GMES) is the most ambitious operational Earth Observation programme to date and will provide global, timely and easily accessible information in application domains such as land, marine, atmosphere, emergency response, climate change and security. To accomplish this, the European Union (EU)-led GMES programme comprises three components namely the space component, the in-situ component and the service component. The space component, led by ESA, is in its pre-operational stage, serving users with satellite data acquired by the so called "GMES Contributing Mis-sions" already available today or planned at European, national and international level. It will become operational once the dedicated space infrastructure, comprised by the "Sentinel" missions and their corresponding ground segments are operational. The first of these satellite series will be launched in 2013. The Sentinel missions will provide a unique set of observations utilising different techniques spanning C-band SAR, mid to medium resolution optical and thermal observations with increased spectral resolution, al-timeter and dedicated spectrometers for atmospheric chemistry. This data, combined with in-situ data, some assimilated into models, will then be turned into services for monitoring the environment, the climate and for security related issues. The GMES Space Component (GSC) is organised in two overlapping phases: the development phase and the operational phase, the latter planned to start in 2014. The main challenge is now to ensure the programme's long-term sustainability.

T he ESA Sentinels will be the first series of loperational satellites to meet the Earth observation needs of the European Union-ESA Global Monitoring for Environment and Security (GMES) programme. The pair of Sentinel-2 satellites will routinely provide high-resolution (10–20 m) optical images globally with frequent revisits tailored to the needs of GMES land and emergency services. Sentinel-2 aims at ensuring continuity of Spot-and Landsat-type data, with improvements to allow service evolution. The first launch is expected in 2012. What Users Need The pair of Sentinel-2 satellites will routinely generate valuable information for the European Union (EU) and its Member States as part of the Global Monitoring for Environment and Security (GMES) programme, in the areas of global climate change (Kyoto Protocol and ensuing regulations), sustainable development, European environmental policies (such as spatial planning for the Soil Thematic Strategy, Natura 2000, and the Water Framework...
