The antenna is housed within a pre-existing mast with an integrated radome (different from the default Septentrio radome, which is removed) at JAXA's Tsukuba Space Centre, Japan.

A joint collaboration between JAXA and ESA/ESOC was established in March 2015.

TSBA provides crucial coverage for the Eastern part of the Asian continent, as well as the Northwest Pacific Ocean, with BANT being the next closest station at more than 5400km. 


In June 2015 a Septentrio PolaRx4 receiver was installed together with a Septentrio Chokering MC antenna,  providing multi-GNSS tracking from this location: GPS, Glonass, Galileo, Beidou and QZSS.

In December 2019 the equipment was upgraded to a Septentrio PolarRx5 receiver and a Septentrio PolaNt Chokering B3/E6 antenna
