Envisat, the ground stations and Artemis

Artemis

In July, ESA launched Artemis (Advanced Relay and Technology Mission Satellite), an advanced telecommunication satellite.

Its most innovative application will be the transmission of data – both by radio links and by laser – from one satellite to another.

As a result, Envisat will sometimes be able to relay its data to Earth via Artemis, rather than always having to be in contact with a ground station or storing data on board on tape or solid-state recorders. This is a particular advantage for the high data rate instruments, MERIS and ASAR.
