Hello guys, I was wondering why are there 3 accelerometers, 3 gyroscopes, and 2 barometers? Are they used for data fusion in order to increase the accuracy of the measurements? or simply if one is down the other will replace it to maintain stability? Do I have access to each measured value by every…

IMU Anti-Vibration Mounting Cube Autopilot

Absolutely! IMU 1 and two give you a redundancy on physical IMU failure, but as they are mounted on a seperate board, if something happens to that board, then you loose both IMU’s So by having one IMU mounted to the FMU board, we eliminate the risk of being left without an IMU. There are multiple scenarios where this could happen that are a lot more normal than people may think… For example, if you hit a harmonic frequency of the isolation board, the IMUs could be much worse than the fixed u…
