Best practices for tracking drift and measuring performance

[carbotaniuman]

Hello Kris,

I'm currently developing an IMU for a closed ecosystem and I wanted to compare my solution to existing COTS products (mainly heading wise). Do you have any tips on accomplishing this?

Thanks

Get a low-cost rotary stage for reproducible testing, like this <https://hackaday.com/wp-content/uploads/2019/03/hackaday_journal-gregorytomasch_kriswiner-heading_accuracy_using_mems_sensors.pdf> one. Put your solution together with other COTS solutions on the same pcb for ease of testing. Develop a standard calibration procedure, etc.

@kriswiner I got something set up. Is there anything better for 6DoF accel + gyro fusion than an Extended Kalman Filter?

Better, don't know. Different, there is this <https://github.com/kriswiner/MPU6050/blob/master/quaternionFilter.ino>.
