2 EO missions handled by ESA METEOSAT M-1, 2, 3, 4, 5, 6, 7 METEOSAT Second Generation MSG-1, -2, -3 METOP-1, -2, -3 Meteo in cooperation with EUMETSAT ERS-1, -2 Earth Explorers GMES ENVISAT Cryosat 2 (Polar Ice Monitoring) GOCE SMOS (Soil moisture) Third-Party Missions: European access to non-esa missions ALOS, SPOT, Landsat, Kompsat-2, Scisat... (Gravity and Ocean Circulation Explorer) ADM/Aeolus EarthCARE SWARM ESA Sentinels satellites + National missions (e.g. SPOT, Pleiades, TerraSAR, Cosmo-Skymed,...) Science to better understand the Earth Applications Services to initiate long term monitoring systems and services European users

3 ERS 1 and 2 ERS 1 ( ): Oceans, sea ice, cryosphere, land surface & climatology ERS 2 (1995 still operational): ( ) plus global ozone & terrestrial biosphere monitoring Results of 16 years ERS missions: basis for long-term environmental monitoring climate change research results from ERS have been of relevance for IPCC wealth of science and application results consolidation of a large EO community

4 ERS-2 mission ERS-2 after 12 years mission: technically ERS-2 is performing well, however power budget needs to be monitored LBR station extension continues All missions fully supported; since 2006 also the classical interferometry ERS-2 SAR mission is one of the fastest SAR mission. Planning request in the morning results in data on disk in the evening Some problems with the platform (gyroscope in 2001, tape recorder in 2003) but all instruments still functioning well engineering solutions have been developed: - new 'gyro-less' working mode - set up of a station network for Low Bit Rate data recovery

6 ENVISAT mission Envisat operations funding until different types of ESA Envisat data products 280 Gigabytes of data products generated per day at ESA 500 Terabytes to date Envisat mission: Category 1 use registration or proposal: ESA web portal: Envisat images:

7 Envisat & ERS-2 missions extension The proposal for the EO Envelope Programme 3rd Period ( ) includes, in its Development and Exploitation component, the provision for operating the ERS-2 satellite until 2008 and the Envisat satellite until The current spacecraft status allows to further extend the operations of both missions by 3-years in order to respond to the user communities demand, i.e. until 2011 for ERS-2 and until 2013 for Envisat. The Envisat 3-years extension requests a modification of the orbital parameters in 2010 as the on-board hydrazine will be almost completely consumed by ERS-2 approved mission 3-years extension Envisat approved mission 3-years extension New orbital parameters To be approved by DOSTAG and PB-EO

9 How to extend Envisat satellite lifetime beyond 2010? Extension scenario. End of phase E3 (i.e. nominal mission): (56 kg ± 15 kg remaining fuel) ~ October Altitude change: km (~34 kg needed fuel). Phase E4 (i.e. extended mission): (22 kg ± 15 kg available fuel). Repeat cycle: 30 days / 431 orbits. Orbit control: altitude only, inclination drift. MLST variation: first, 22:00 to 22:10, then 22:10 to 21:50. Artemis availability expected up to 2013 (to be confirmed with Artemis team). End of phase E4: ~ mid 2014 (00 kg ± 15 kg remaining fuel)

17 Earthnet and Third Party Missions Objectives: The Earthnet Programme Serving European users with non-esa / non-european data Fostering European user communities and science competence Synergistic use and joint exploitation of ESA and Third Party data Complementing existing ESA Earth Observation Missions Setting up Ground Segment co-operation (e.g. contingency agreements, joint mission planning) Long-term commitment: EARTHNET has been established 30 years ago! The historical JERS-1 mission

18 Earthnet and Third Party Missions Third Party Missions Missions not operated by ESA for which ESA assumes some responsibility / contributes financially (sharing of Ground Segment facilities or operations cost) for which ESA assumes a data distribution responsibility, mainly towards the European Scientific User Community

27 Data policy defined by ESA Member States: ESA Earth Observation Policy to stimulate a balanced development of Science, Public Utility and Commercial Applications, consistent with the mission objectives, to maximize the beneficial use of data from ESA EO satellites. Project purpose Distribution responsible Data costs Category 1 use Research, Applications Development Most of ESA data (e.g. MERIS) available only through Cat.1 Category 2 use SAR & HR optical data available in Cat.1 or Cat.2 esa using ESA facilities/stations competing Distributing Entities using ESA facilities and/or agreements with non-esa stations SARCOM (Spot Image) EMMA (Eurimage) Costs of reproduction Free on Internet Cat.1 use Terms & Conditions Data costs defined by competing Distributing Entities

28 How to apply for data access within a Category 1 use framework? Application for Category 1 use data access can be submitted to ESA at any time using the ESA Earth Observation Principal Investigator portal (
