LINZ publicly broadcasts real-time, one-second Global Navigation Satellite System (GNSS) data. The data is streamed free-of-charge from 39 Continuously Operating Reference Stations (CORS) throughout New Zealand. This includes 34 LINZ PositioNZ stations and 5 stations which are part of the GeoNet project run by GNS Science. Users can connect to a data stream in the field using their GNSS receiver and a cellular connection. This enables Real-Time Kinematic (RTK) positioning to be carried out, without the need to set up a separate base station. To help monitor the reliability of the network, LINZ has established an online monitoring tool on the PositioNZ-RT webpage.
