x-IMU3 User Manual v1.7
January 5, 2024
Notes
1. Each update includes a timestamp for a reliable measurement of time independent of the update rate
error. See Section 9 on page 34 for more information.
2. The Attitude Heading Reference System (AHRS) update rate is fixed independent of message rate
settings. AHRS outputs are not averaged when the message rate is less than the update rate.
