PositioNZ is LINZ's Global Positioning System Active Control Network. Through this site you can download GPS 30 second RINEX files from the active control stations which you can use with remote GPS station data to determine precise positions in terms of New Zealand Geodetic Datum 2000. More ....

PositioNZ-RT – real-time data streams

Find out how to access real-time data from PositioNZ stations. more...

Precise satellite orbits can be obtained from International GPS Service (IGS).


Preparing PositioNZ-RT for Multi-GNSS – can you connect?

We are taking advantage of the new satellite positioning systems now available in New Zealand by providing the RTCM 3.2 MSM (Multiple Signal Messages) format which offers faster and more accurate positioning. It will eventually replace the current format across the network.

Can you connect to the new format? We want to know?

Let us know before 30 September on the feedback form or read more about the change.
