GNSS reference station
GNSS stands for Global Navigation Satellite Systems. This is a collective name for navigation systems such as GPS, Galileo, Glonass and Beidou. GNSS reference stations are being set up on offshore platforms. A GNSS reference station is a combination of a GNSS antenna and a GNSS receiver.
The GNSS reference stations are part of the GNSS reference network of the Dutch Geodetic Infrastructure Cooperation (NSGI), a collaboration between the Land Registry, Rijkswaterstaat and the Hydrography Service. The NSGI GNSS Reference Network continuously records GNSS observations.
The GNSS reference network forms the link between the traditional reference systems of the National Triangle Survey, the Normal Amsterdam Level and international reference systems such as WGS84 and ETRS89. The Land Registry and Rijkswaterstaat use the system to carry out surveying and hydrographic work. The GNSS reference network is also used for research, such as monitoring ground motion, sea level rise and research into ionospheric and tropospheric delay of the GNSS signal.
Data
The data collected with the GNSS reference station can be found on the NSGI website, in real time and in file form.
Customers and applications
The data is used for accurate positioning in the context of surveying and hydrographic measurements and maritime research, water level measurements (see the website of the Permanent Service for Mean Sea Level, the global database for information on long-term sea level changes) and research applications, for example research into sea level rise or meteorological research.
