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
