+     Calling getPVT would return false now (compare to previous example where it would return true), so we just use the data provided
      If you are using a threaded OS eg. FreeRTOS on an ESP32, the explicit mode of autoPVT allows you to use the data provided on both cores and inside multiple threads
      The data update in background creates an inconsistent state, but that should not cause issues for most applications as they usually won't change the GPS location significantly within a 2Hz - 5Hz update rate.
      Also you could oversample (10Hz - 20Hz) the data to smooth out such issues...
