Usuda Deep Space Center

Usuda Deep Space Center is a facility of the Japan Aerospace Exploration Agency[1] It is a spacecraft tracking station opened in October, 1984. The main feature of the station is a 64 meter beam waveguide antenna.[2] This was the first deep-space antenna constructed with beam-waveguide technology.

Before Usuda, the beam-waveguide construction, which dramatically simplifies installation and maintenance of electronics, was thought to offer poor noise performance.[3] However, after the U.S. Jet Propulsion Lab (JPL) tested this antenna and found the noise performance was better than its conventional 64-meter antennas,[4] it too switched to this method of construction for all subsequent antennas of their Deep Space Network (DSN).
