Strange acceleration reading

Posted by shai on August 22, 2015 at 1:19pm

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?

      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?

          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?

              Thanks for your help.

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

              FAILSAFE_GCS-0, FAILSAFE_GCS-1 errors.
