SSC provides the THEOS mission with uplink and downlink communication services during the so called LEOP – Launch and Early Orbit Phase – covering the 15 first days of the mission. After launch, SSC’s Esrange Satellite Station had its first contact with THEOS at 08.07 UTC. The station now communicates with the satellite each time it passes over Esrange’s horizon, i.e. nine times a day.
The services are provided by contract with EADS Astrium which built THEOS for GISTDA, the Thai Ministry of Science and Technology
