Returns the percentage of the GPS self survey that is complete. During a self-survey, the onboard GPS receiver performs position fixes, then the individual position fixes are accumulated and averaged. Therefore, the GPS time reference and location information are most accurate after the self survey has completed and least accurate at the beginning of a self survey. If you have set GPS as the selected time reference, wait until the self survey is complete prior to beginning timing measurements for the most accurate results.
The onboard GPS receiver requires at least four visible satellites to perform a self survey.
