ESA Earth Observation 2007 budget
14.7% = 437 M€
17 years of ERS-1/2 SAR data in the archive
ERS-2 achieved 13 years in orbit in April 2008
ERS-2 was designed for 3 years nominal lifetime !
Ample hydrazine ~ 50% left after 13 years
Platform
preventive measures are implemented on the power system to
compensate for ageing
Instruments
all instruments work satisfactorily and provides useful data
Good prospect to operate ERS-2 mission until 2011
ERS-1 and ERS-2 missions
Exploitation of the synergy between ERS-2 and Envisat
same ground track with 30 minutes time difference
ERS-2 / Envisat InSAR Tandem periods:• ERS-2 orbit is shifted by 2 km w.r.t. Envisat orbit• First period: September 07 to February 08• Second period: November 08 to January 09

envisaged 3-years extension
Sentinel-1
approved 3-years extension
New orbital parameters
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 2010.
The following criteria were used to find a solution for extending Envisat beyond 2010:
• to keep the current nominal mission for as long as possible (i.e. until 2010),
• to extend the mission well beyond 2010,
• to ensure the continuity of the max. number of Envisat applications beyond 2010,
• to follow the mitigation rules for space debris risk at end of mission.

METEOSAT Third Generation
Services Component
• Produces information services in response to European policy priorities in environment and security
• Relies on data from in-situ and space component
In-situ component
• Mostly of national responsibility, with coordination at European level
Space Component – role of ESA as
• development agency for dedicated infrastructure
• coordinator of contributions from Member States, EUMETSAT, private and commercial partners
Kopernikus components
Baseline use by FP7 funded

Simplified user registration procedures for Category 1 use
Internet access to Near Real Time (NRT) data
Internet access to archived data gradually implemented (new dataset, new access systems)
