Channel Name Definitions - IMU Attitude

Channel Name	Description	Unit
Head_IMU	Head_imu is the heading of the body of the vehicle generated by the Kalman filter (using GNSS and Inertial data). This channel will be affected by any misalignment of the IMU and as such care should be taken to align the IMU with the direction of travel.	°
Pitch_IMU	Pitch_imu is the pitch angle measured in degrees, generated from the Kalman filter (using GNSS and inertial data). This channel includes any offset applied after performing a "Pitch Angle" calibration.	°
Roll_IMU	Roll_imu is the roll angle measured in degrees, generated from the Kalman filter (using GNSS and inertial data). This channel includes any offset applied after performing a "Pitch Angle" calibration.	°
Pos.Qual.	An estimate of the current positional accuracy: 10 = Less than 5cm 9 = Between 5cm and 10cm 8 = Between 10cm and 1m 7 = Between 1m and 2m 6 = Between 2m and 10m 5 = Greater than 10m 2 = IMU is waiting for intialisation 1 = IMU is not yet synchronised
Lng_Jerk	The Longitudinal Jerk as defined by the rate of change of the longitudinal acceleration as generated by the Kalman filter. This channel is smoothed by 0.5 s for compliance with UN R79 testing.	m/s³
Lat_jerk	The lateral jerk as defined by the rate of change of the lateral acceleration as generated by the Kalman filter. This channel is smoothed by 0.5 s for compliance with UN R79 testing.	m/s³
