I want to make a gyroscope for an airplane, but I have a question before I buy the UM7. Has anyone tested this sensor in an airplane? I have several sensors, but all of them have a problem with dynamic acceleration, which means: when turning (or accelerating) the horizon does not remain stable horizontally, but also deflects according to the angle of the lateral acceleration vector. An artificial horizon in an airplane must always show a stable level regardless of the forces acting on the airplane.
That is a failure of the simple AHRS algorithms used with consumer grade IMUs, which assume that the Down reference is the accelerometer reading, and that the acceleration is only due to gravity.
Commercial instruments use much more sophisticated sensors and algorithms, and consequently cost several orders of magnitude more.
Yes, but UM7 is marketed as an AHRS system and therefore I expect it should work in an aircraft and behave like a real gyro.
AHRS is shorthand notation for Attitude and Heading Reference System (pitch, roll and yaw, also called MARG). Nothing more is implied.
Let me know if you are happy with the UM7.
This is exactly I need: pitch, roll and yaw, but in accelerating and turning vehicle. For example I bought BNO085 with pitch, roll, yaw reports. It’s not working good in airplane (in car too). When you accelerate, then pitch is changing but it shouldn’t. When you turn in car on flat surface the roll is changing but it shouldn’t. I’m looking for device designed for this situations.
I explained why pitch changes in the first response to your post. It is a difficult problem and the solution is expensive.
