The ENVISAT satellite (ENVIronmental SATellite), successor of ERS-1 and 2 was launched on March 1st, 2002. Dedicated to the study of the environment, in particular to the follow-up of climate change, its mission is to observe the atmosphere and the surface of the Earth. Built by ESA, it has on board a series of additional instruments (with a radar altimeter RA2, the system of orbitography and precise location DORIS) allowing it to observe a large number of geophysical parameters.
A more detailed description of the ENVISAT mission is found on the ESA site
Nominal paths are described in ERS-2/Envisat nominal path and Envisat new orbit
