Step 3: Power on LinPAC
After boot the Linux OS, the LinPAC will automatically launch the application and get the
GPS/GLONASS time to minimize the RTC drift to 1 millisecond. Using “ntpq –p” command to check
the time’s error (the time error < 1ms). Please refer to below diagram:
Tips & Warnings
Sometime the ntpd daemon need to spend 10~20 minutes to minimize the time
error, so the command “ntpq –p” can’t show the symbol ‘o’ or time error less
than 1ms immediately.
