The Kiruna S- and X-band station supports Envisat and ERS-2, and is scheduled to support CryoSat-2 in 2009. For ESTRACK, Kiruna hosts one 15m and one 13m antenna. Both operate in S-band for uplink and downlink and X-band for downlink. The station is located at Salmijärvi, 38 km east of Kiruna, in northern Sweden. The station is equipped for tracking, telemetry and command operations as well as for reception, recording, processing and dissemination of data from the sensor instruments onboard ERS-2 and Envisat.
The station is connected to the ESTRACK Control Centre (ECC) at ESOC via dedicated voice and data circuits. The station is remotely monitored and controlled from the ECC under nominal operating conditions. A mini control centre is located at the station to provide backup.
