Space Radio Monitoring Facility is installed in the Kanto Telecommunications Bureau, and supervise downlinks of L, S, C, Ku, and Ka bands from visible geostationary satellites.

Based on satellite-transmitted downlink spectrum wave information, the facility automatically identifies the location of geostationary satellites and the source of various electromagnetic waves.

Although this facility automatically operates on a registered schedule, operators may also use it at any time to conduct manual measurements.
