SGO's Ionospheric Tomography Chain has been in operation since November 2002. The five beacon satellite receivers station of SGO have been in Kiruna (Sweden), 2002-. Kokkola (Finland) 2002-, Nurmijärvi 2004- , Luleå 2002-2014, Kilpisjärvi (Feb 2004-2013) and and Tromsø (Norway) 2002-2004, which was moved to Kilpisjärvi in 2004. There has been special tomography measurement campaigns combined with the Finnish EISCAT Campaigns since 1995. The present receivers are capable to receive beacons of the Russian Low Earth Orbit satellites at 150 and 400MHz. The satellites are old.

Past years FMI has built TomoScand receiver network to Scandinavia, which are capable to receive also other beacon satellites at 150 and 400MHz bands. Upgrading of the present SGO receivers is scheduled for 2016-2017 in RLab project. These two networks will form joint SGO-FMI tomography network in near future.
2 active satellites (103, 106)
3 (of 5) receiver stations ( KIR, KOK, NUR) in operation
