ESOC GNSS Station at New Norcia (NNOR)

An ESOC Navigation Support Office GNSS station participating in the IGS network

Location

The receiver is located at the ESA New Norcia station, that is approximately 100 km north of the city of Perth on the western coast of Australia. The station hosts a 35 meters antenna and a redundant Hydrogen Maser that provides the reference frequency to the GNSS receiver.

History and Evolution

The Ashtech Z-XII receiver was tested at ESOC and installed at the station on 17th June 2002.

in October 2012 a Septentrio Polarx4 receiver and a septentrio chokering antenna were installed.

Equipment

The receiver is located in the Main Equipment Room of the station. It is connected to the Hydrogen maser oscillator. A computer provides for the operation and remote control of the system.

The station has pressure, temperature and humidity meteorological sensors available.

The communications are carried out using the permanent lines to the ESA control centre ESOC. Data are downloaded evey 15 minutes and distributed to the scientific community.

The monument is similar to the others constructed in the ESA stations. It is located at the best possible location taking into account the requirements of visibility, stability, proximity to the main Equipment Room and security.
