What Datum is my RINEX header position in?

RINEX header information for all CORSnet-NSW data is now in GDA2020. Industry standards dictate that RINEX header positions are approximate only. It is highly recommended that you use the stations certified position which is in both GDA2020 and GDA94 (2010) at https://www.spatial.nsw.gov.au/corsnet-nsw/network_information. Alternatively the coordinates can be obtained from SCIMS Online (essential for connection to GDA94).   


Is my local base station down?

You can check live status of all CORS in the network from our web portal.

If the CORS is displayed with a yellow or red icon it means the CORS is not available.

For extended outage that may span multiple days, we also issue an alert via the RSS feed. Access our guide on how to subscribe to the CORSnet-NSW RSS feed. 

Is CORSnet available in GDA2020?

Yes CORSnet-NSW is available for real-time users in both GDA2020 and GDA94. Instructions on how to connect to either of these services are available on page 8 of the User Guide.  Station coordinates are calculated in GDA2020 and are subject to Regulation 13 Certification.

How do I determine AHD heights using GDA2020?

To get accurate AHD heights while using GDA2020 you will need to make sure your equipment is using the correct geoid. AUSGeoid09 will only give accurate results when using GDA94. When using GDA2020 you should use AUSGeoid2020. Contact your equipment supplier for further help with your particular hardware.   

Connection issues in the field

Rover is not connecting to the Internet

Please contact your reseller who can assist with your rover dialup process.

Rover is connected to the Internet but is not connecting to CORSnet-NSW

Check that you are using the correct settings on your rover (NtripCaster address, port number, mountpoint name, login name, password). The NtripCaster address must be corsnet.nsw.gov.au with port number 2101 for GDA94 coordinates or port 2020 for GDA2020 coordinates.

If you are still having issues, contact CORSnet-NSW Customer Support. We will check your login name and password, subscription status and also simulate a connection using your login details to confirm. Common problems are incorrect login name or password, locked account (due to invalid multiple attempts), expired subscription or attempt to connect more than one rover.

Rover is connected to CORSnet-NSW, but no correction data is received

If you are using the VRS or Nearest-CORS service, ensure that your rover is configured for VRS so that it will send its position to our system.

If you are using the Single-Base service and manually connecting to a specific CORS, check the availability of the CORS on our Live Map.

Rover is receiving correction data, but has intermittent dropouts

This could indicate the following:

  • Poor mobile Internet coverage.
  • Poor sky view and hence poor tracking of GNSS satellites at the rover.
