Perform clock correction with I/NAV

This page contains some general guidelines and suggestions for developers who wish to implement their own software using HERE HD GNSS data.

Galileo I/NAV and F/NAV

Galileo ephemerides provide different clock models for I/NAV and F/NAV, but the HERE HD GNSS service does not provide clock corrections for both. I/NAV clock model has been chosen to be the reference when deriving clock corrections. Hence, when using correction data provided by HERE HD GNSS service, you should use I/NAV ephemeris and clock correction data with all Galileo signals.
