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
