Strange acceleration reading

Hello,

 

I downloaded the flight logs from my Pixhawk through the Mission Planner Software and saw something strange.

While the X and Y Acceleration Graphs where centered around 0, the Z Acceleration was centered around -10.

Is this normal?

What can be the cause?

  • Yep. Gravity.

    • Thanks for your reply!

      As you can see, the Pixhawk enters into FAILSAFE_GCS-1 and later FAILSAFE_GCS-0.

      What is the reason?

      What does each failsafe mode mean?

      • Ground Control Station Failsafe.

        • Thanks for the information.

          But I'm still having trouble understanding the graph.

          Please walk me through it...

           

          Around time 25 the following error kicks in:

          Err: FAILSAFE_GCS-1

          It disappears around time 60.

           

          Then around time 100 the following error kicks in:

          Err: FAILSAFE_GCS-0

          It disappears around time 135.

           

          Then around time 150: FAILSAFE_GCS-1 reappears.

           

          Can you explain exactly what's happening?

           

           

          • I can't say what the difference between FAILSAFE_GCS-0 and FAILSAFE_GCS-1, but in either case, the communications between your ground control station and the machine has been lost. Maybe someone else knows what the difference is.

            Since telemetry is non-critical (usually), you can turn it off in Mission Planner. Set FS_GCS_ENABLE to 0.

            • Thanks for your help.

              This is really frustrating. I can't find any information about the  

              FAILSAFE_GCS-0, FAILSAFE_GCS-1 errors.
