An internal (non-public)  ESOC Navigation Support Office GNSS station.

Location

The antenna is situated on the roof of one of the buildings within CENAM ( National Metrology Center)  premises, approximately 10km outside the city of Santiago de Querétaro, Mexico.

While operated by CENAM, the management of the station is done through  AEM ( Mexican  Space  Agency).

A joint collaboration between AEM   and ESA/ESOC was established in August 2018.

Equipment

In February 2019 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.
After some initial observation data analysis, the antenna was moved to its final position (~30m further along the same roof) in March 2019. 

In April 2021 the equipment was upgraded to a Septentrio PolarRx5 receiver and a Septentrio PolaNt Chokering B3/E6 antenna
