Usuda Deep Space Center

Usuda Deep Space Center is a facility of the Japan Aerospace Exploration Agency. It is a spacecraft tracking station in Saku, Nagano, opened in October, 1984. The main features of the station are two large beam waveguide antennas, an older 64 meter antenna and a newer 54 meter dish.

Misasa Deep Space Station
Misasa Deep Space Station (MDSS) is now the world's most sensitive antenna for Ka-band communication worldwide. It is located 1.3 km from Usuda and is also administrated and maintained by the Usuda Deep Space Center. This new antenna had the name GREAT (Ground Station for Deep Space Exploration and Telecommunication) during the construction. It is 54 meters in diameter and has an adaptive surface with high accuracy and efficiency, and hence is capable of working at the higher Ka-band frequencies. This will increase the potential data throughput despite the smaller size. ==Public Access Classification==
