Commercial ground station network operated by KSAT (Kongsberg Satellite Services). The largest commercial ground station network globally with antennas at more than 25 sites spanning polar (Svalbard at 78 N, Troll at 72 S) to equatorial latitudes. The Svalbard and Troll stations are the structural differentiator: at high latitudes a polar-orbiting EO satellite passes over the station every orbit, providing 12 to 14 downlink opportunities per day per station versus 2 to 4 from equatorial-only networks. Service offering covers mission operations, telemetry, tracking and command, downlink, and data delivery for EO, communications, scientific, and smallsot operators. KSATlite is the productised smallsat-tier service. The April 2026 strategic partnership with NanoAvionics integrates KSAT ground services into the NanoAvionics standard mission stack.
KSAT (Kongsberg Satellite Services) operates a commercial ground station network spanning polar, mid-latitude, and equatorial sites globally.[1] The network's polar anchor stations are SvalSat at Svalbard (78 N) and TrollSat at Antarctica (72 S).[1] SvalSat hosts over 160 antennas and supports contact with a polar-orbiting satellite on each of 14 daily passes.[2] USGS confirms that the Svalbard station provides access to every orbit for most polar-orbiting satellites.[3]
The network spans 40+ ground station locations globally, with several hundred antennas.[1]
Supported frequency bands include S-band, X-band, Ka-band, VHF, and UHF.[4] The 24/7 Network Operations Centre in Tromso coordinates the global network as one interconnected facility.[3]
Services cover telemetry, tracking and command (TT&C), mission operations, downlink, and data delivery for EO, communications, scientific, and smallsat operators.[1] KSAT's Digital IF architecture digitises the RF spectrum at the antenna and routes it to software-defined processing applications in a ground station cloud environment.[5] KSATmax is the full-service tier for larger mission programmes,[6] while KSATlite is the productised service tier targeting smallsat operators with standardised, cost-optimised ground contact packages.[7]
Heritage traces to the Tromso Telemetry Station established in 1967 and SvalSat opening in 1997.[1]
