NZ Government GNSS CORS

The NZGD2000 Government CORS provides the locations of GNSS Continuously Operating Reference Stations operated by GNS Science under the GeoNet project ( http://www.geonet.org.nz ). Coordinates are from the LINZ Geodetic Database, in NZGD2000.


These are split into several different networks:


- PositioNZ - stations predominantly funded by LINZ, with some GeoNet funding. These provide a nationwide coverage of ~120km spacing. More info [here]( http://apps.linz.govt.nz/positionz/ )

- GeoNet - stations funded by the GeoNet project. These are located in areas of geophysical interest, usually on the East Coast of the North Island. More info [here]( http://www.geonet.org.nz )

- SAGENZ - stations funded by the University of Otago, GNS Science, MIT, University of Colorado and UNAVCO. These Southern Alps Geodetic Experiment - New Zealand stations are generally semi-continuous sites.

- Tide Gauge - stations co-located with tide gauges at major ports. Data is managed through the GeoNet project also.


30" RINEX data from all of these sites is available from the [GeoNet website]( http://www.geonet.org.nz )


Real Time data is available from all PositioNZ stations, and some GeoNet stations. For more information, see the [PositioNZ-RT website]( http://apps.linz.govt.nz/positionz/rt/index.php )

Statement

These coordinates are generated by GNS Science by processing several days of GNSS data in the Bernese software package. They were then converted to NZGD2000, and loaded into Landonline.

They are considered to be very consistent internally, however they have not been connected to local geodetic control. Because of this there may be inconsistencies between the coordinates of these CORS and local geodetic control marks.


Initial stations were installed as early as 1995, operated by GNS Science. SAGENZ and Tide Gauge stations came online around 2000. PositioNZ and GeoNet stations began construction in late 2002, and these networks have been expanding since. The PositioNZ network is now at a stable number, however new GeoNet stations are still being installed.
