My name is Aliaksei. I'm an engineer. While using IMU ADIS16488 several days ago I found out some strange feature of this IMU. I made three tests trying to compensate zero drift on Z-axis (results are logged on the picture below), but Z-axis velocity walk-down changes its direction after power switching on and makes such compensation quite difficult. I can see such strange behavior only working with Z-axis (X and Y axis are OK). Please explain this situation.
I’m looking forward to hear from you.
