The ENVISAT Mission - Observing our Planet from Space

Kurzfassung

In March 2002, the European Space Agency ESA launched ENVISAT, one of todays large Earth Observation missions. ENVISAT carries a multitude of instruments to study our environment, i.e. land, ocean and atmosphere, in great detail. With an expected lifetime of about 5 years ENVISAT will provide us with a continuous flow of information. The presentation gives an overview of the mission concept and the various instruments on-board. Particular emphasis is given to applications of the Doppler Principle. Therefore three instruments are described in detail: DORIS, ASAR and SCIAMACHY. Finally, first results from more than 1.5 years in orbit are presented.
