## Editorial
KSAT (Kongsberg Satellite Services) is a Norwegian commercial ground station network operator and EO analytics service provider, headquartered in Tromsø and incorporated in 2002. The company traces its operational heritage to the Tromsø Telemetry Station inaugurated in 1967 and the Svalbard Satellite Station (SvalSat) established at Plataaberget in 1997.[^ksat-about]

KSAT is owned equally (50/50) by Space Norway AS, a Norwegian state enterprise, and Kongsberg Defence and Aerospace AS, a subsidiary of the publicly listed Kongsberg Gruppen technology group.[^ksat-about] The company employs more than 600 staff, the majority at Tromsø headquarters.[^ksat-about]

The ground segment infrastructure is the company's structural asset. KSAT operates a global network of several hundred antennas across 40+ locations spanning polar to equatorial latitudes.[^ksat-about] SvalSat, at 78 degrees North on Spitsbergen, hosts more than 100 antennas and provides a contact window on every orbit for polar-orbiting EO satellites.[^svalsat-wiki] The Troll Satellite Station at 72 degrees South in Antarctica, operational since 2007, provides complementary southern polar coverage.[^ksat-about] Together, SvalSat and Troll enable near-continuous downlink coverage for sun-synchronous and polar-orbiting missions. The main network supports X-band, S-band, Ka-band, and other frequency bands and serves traditional large EO platforms, communications satellites, and science missions across LEO, MEO, GEO, and HEO.

KSATlite is KSAT's dedicated service tier for small satellites and constellations. Celebrating its tenth operational year in April 2026, KSATlite operates 135 antennas across 26 globally distributed stations and serves over 150 satellite operators for Earth observation, satellite communications, and IoT applications.[^ksatlite-page] The service is API-driven and fully automated, supporting S-band, X-band, and Ka-band contacts.[^ksatlite-page]

Beyond downlink and mission operations, KSAT provides EO analytics services including environmental monitoring (oil spill detection with more than 20 years of operational history, fisheries surveillance, InSAR land deformation, and forestry monitoring) and maritime situational awareness via its Vake platform, which fuses SAR satellite imagery and AIS data to detect and track dark vessels.[^ksat-env]
