[MSD42-P03] Ten years history of Tohoku University ground station and operation system for micro and nano satellites
Keywords:microsatellite, satellite operation, ground station
Ground station in Tohoku University, called CRESST, was refurbished for our 1st satellite SPRITE-SAT in 2009. In these 10 years, the station used for total 6 microsatellites and 4 cubesats. Low earth orbit satellites are flying over the station for 9 to 12 minutes per opportunity, and the antennas and transceiver frequencies are controlled by calculating the satellite orbits. By only setting the target satellite names, the station is automatically woken up, controlled properly, and suspended again. Operations are not necessary to manage the antennas, and can concentrate on the communication with satellites.
Currently, more 3 satellites, DIWATA-1, RISING-2, and SPRITE-SAT are also tracked and communicated as well as latest 3 satellites. The satellites compatible to this station are registered as JCUBE-B group satellites in International Telecommunication Union. Several satellite are planned to use this station in a few years. The register to ITU will spend the time more than 1 year, and this can make a trouble in project schedule. A satellite can be completed in 1 to 1.5 years in short-term project, and radio license can be a matter. By using this station and compatible radio specifications, it will promote a new satellite project and expand the collaborative partners.
