This is what I am getting now and just wanted to ask what kind of values other people have and consider acceptable.
Using the Mission Planner or other GCS graph the VIBE message’s VibeX, VibeY and VibeZ values. These show the standard deviation of the primary accelerometer’s output in m/s/s. The image below, taken from a 3DR IRIS, shows normal levels which are below 15m/s/s but occasionally peak to 30m/s/s. Maximum acceptable values appear to be below 60m/s/s (see second picture below).
