The TerraSAR System comprises two radar satellites which operate
in different frequencies and thereby optimally complement each
The TerraSAR mission has its origin in an industrial initiative
to provide market-derived X- and L-band SAR products from a pair
of spacecraft operating in tandem in a sun-synchronous orbit. It was proposed by the British National Space Centre (BNSC)
and the German Aerospace Centre (DLR) for implementation as an
element of ESA´s Earth Watch programme.
TerraSAR-X has become a German national programme jointly funded
by DLR and EADS Astrium GmbH. Contracts have been signed, and
TerraSAR-X is currently being constructed by Astrium
GmbH, while DLR is setting up the core ground system and Infoterra
GmbH prepares commercial sales of data and future geo-information
TerraSAR-L is subject of a definition study led by EADS Astrium
in the UK in the framework of the ESA TerraSAR Consolidation Phase.
From 2006, the new 1 metre resolution radar satellite TerraSAR-X
will be delivering Earth observation data for scientific, institutional
and commercial users. TerraSAR-X will be the first satellite realized
in a Public/Private Partnership in Germany, as EADS Astrium GmbH
and the German Aerospace Centre (DLR) share the costs for construction
and implementation of the satellite.
Following substantial investments into the development of geo-information
products and market development, EADS Astrium´s 100%-subsidiary
Infoterra GmbH has now started the marketing of the exclusive
commercial exploitation of TerraSAR-X.
TerraSAR-X data can be provided directly from the satellite to
Direct Access Customers (DAC) or Direct Access Partners (DAP)
worldwide, or can be obtained from Infoterra GmbH via direct ordering
or through Channel Partners.
