IMU Noise Expectations
-
Hi there, I'm curious about what sort of noise we should expect on the IMUs on the Starling?
Here is the sort of noise I am seeing on my platform:
-
Result of
voxl-inspect-vibration imu_appsduring a flight:
-
Result of plotting
imu_appsas well asimu_px4. Both have similar levels of noise.

@Moderator - any guidance here? Wondering if my unit is perhaps defective.
@awoods ,
Here is a sample log from one of our recent tests using a Starling platform.
You can review the PX4 log here : https://review.px4.io/plot_app?log=3a4c53fd-db88-4d54-8f2e-5f22e159bfc6
The accelerometer noise looks comparable to yours, perhaps a bit less. The main thing is that motor outputs are pretty clean, very minor oscillations. You can collect a similar log and compare using px4 flight review. Also look at gyro noise which more directly affects motor commands.
