A joint collaboration between INPE, AEB (the Brazilian Space Agency) and ESA/ESOC was established in August 2018


Initially, a Septentrio PolaRx4 receiver and Septentrio Chokering MC antenna were installed at the station in May 2019, providing multi-GNSS tracking from this location: GPS, Glonass, Galileo, Beidou.

In February 2023 the equipment was upgraded to a Septentrio PolarRx5 receiver and a Septentrio PolaNt Chokering B3/E6 antenna.
