Clarification on MediaTek MT3329 GPS

I have this GPS from udrone. I tried the MTK Mini GPS to check the refresh rate and noticed its always 1hz. If I set it to 4hz then power down it will return to 1hz. Is this the normal behavior on MiniGPS and that its not the real update rate APM will be using? Or did I misunderstood it completely? Hope some one can clarify. Thanks

  • Ok found it, I guess the APM is the one setting the update rate as indicated on AP_GPS_MTK.cpp

     

    // set 4Hz update rate
        _port->print(MTK_OUTPUT_4HZ);

     

    In case others would need.
