An internal (non-public) ESOC Navigation Support Office GNSS station.
The antenna is mounted on a small concrete pillar at ground level at the Hartebeesthoek Radio Astronomy Observatory (HartRAO) , South Africa
A joint collaboration between HartRAO and ESA/ESOC was established in April 2017.
Following the long-standing EGON station MAL2 in Kenya, HRTB is the 2nd station to be installed in Africa, providing coverage of the Southern regions together with MTJF.
In September 2017 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
