PositioNZ-PP is a free, automated service that allows users to obtain accurate coordinates without their own base station network or specialised software for processing static GNSS (global navigation satellite system) data. PostioNZ-PP processes a standalone RINEX (receiver independent exchange format) data file against the PositioNZ network of stations to remove ionospheric and tropospheric delays, and clock errors of the receiver and satellites.
This generates:
- New Zealand Geodetic Datum 2000 (NZGD2000) coordinates, which incorporates the New Zealand deformation model
- New Zealand Vertical Datum 2016 (NZVD2016) coordinates
- International Terrestrial Reference Frame 2008 (ITRF2008) coordinates.
PositioNZ-PP uses models based on the positions of PositioNZ stations, which are updated regularly and after significant earthquakes. To find out when PositioNZ-PP is updated, subscribe to the PositioNZ newsletter and station notifications.
