An internal (non-public) ESOC Navigation Support Office GNSS station.
The antenna is mounted on a concrete pillar on the rooftop of a site managed by the Central-Asian Institute for Applied Geosciences (CAIAG) in Bishkek, Kyrgyzstan.
A joint collaboration between CAIAG and ESA/ESOC was established in July 2016.
Centrally located within the Asian landmass, with the nearest EGON station (DUBA) more than 2600km away, BSHK fulfills a key role in ensuring coverage over this area.
In October 2016 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 November 2019 the equipment was upgraded to a Septentrio PolarRx5 receiver and a Septentrio PolaNt Chokering B3/E6 antenna
