High Rate GNSS Data Download

A list of geohazard events where GNSS high rate data has been collected and made available for bulk download in AWS or by request. Learn what events have associated data available and gain access to the data you are interested in.

About high rate GNSS data

High rate GNSS data are available for download for the days surrounding major geologic events. These data are recorded at 1 Hz and 10 Hz sampling rates and are available in RINEX2.11 and Trimble proprietary raw formats. Available high rate GNSS data can be downloaded via AWS Open Data or sending a request via email to info@geonet.org.nz.

Disclaimer

Raw data files are downloaded directly from the GNSS receivers in Trimble proprietary format (.T00 or .T02). Day-long RINEX files are generated by splicing together the available raw data. Due to data transmission constraints and limited internal receiver storage, in most cases it was not possible to download a full day of data so day-long RINEX files are often incomplete. Please consider that high rate GNSS data have to be manually retrieved. There is no guarantee that high rate GNSS data will be available after any major geologic event.
