STCC operates multiple domestic tracking stations. Among them, the seven major stations are listed below.
- Tsukuba Space Center (Ibaraki Pref.)
Tsukuba Space Center has a tracking and control room where 24/365 remote monitoring and controlling of domestic and overseas ground stations is conducted. Playing the pivotal role in JAXA's overall tracking and controlling activities, Space Tracking and Communications Center collects and distributes the data that are received at Tracking and Communications Stations around the world. There is also an antenna located within the premise of Tsukuba Space Center for receiving data from Earth-observation satellites.
- Okinawa Tracking and Communications Station (Okinawa Pref.)
Founded in 1968, Okinawa Tracking and Communications Station is located in the southernmost site as a domestic station.
- Masuda Tracking and Communications Station (Kagoshima Pref.)
Founded in 1974, Masuda Tracking and Communications Station is not only equipped with tracking and control facilities but also with launch monitoring facilities that tracks launch vehicles by a precision radar, receives telemetry signals from the vehicle, and monitors travelling status of the vehicle.
- Katsuura Tracking and Communications Station (Chiba Pref.)
Katsuura Tracking and Communications Station was founded in 1968 and is located in the central region of Japan. The station is characterized by the capability to distribute observation data in a limited time.
- Usuda Deep Space Center (Nagano Pref.)
Usuda Deep Space Center has a large-scale antenna measuring 64 m in diameter which can receive weak radio signals from deep space explorers. This antenna was installed in 1984 to support the first Japanese deep space missions MS-T5 ("SAKIGAKE") and PLANET-A ("SUISEI") and later supported operations of "HAYABUSA2."
- Bisei Space Guard Center(Okayama Pref.)
This facility observes space debris, non-functional space objects, such as end-of-life satellites, spent stages of launch vehicles, and their fragments. The observation of high-altitude (far from the Earth) orbit (36,000 km) where communication satellites are operating as well as small asteroids approaching the Earth is conducted at Bisei using optical telescopes.
- Kamisaibara Space Guard Center (Okayama Pref.)
This facility observes space debris, non-functional space objects, such as end-of-life satellites, spent stages of launch vehicles, and their fragments. The observation of lower-altitude (near-Earth) orbit (200 to 1,000km) where Earth-observation satellites are operating is conducted at Kamisaibara using a radar system.
In addition to the above four stations, STCC also runs Uchinoura Space Center (Kagoshima Pref.) where tracking and data acquisition is conducted. The Earth Observation Research Center (EORC) in Saitama Pref. also has antennas which receive earth observation data.
