Inertial Measurement Unit - IMU03

Racelogic's Inertial Measurement Unit (RLVBIMU03) provides highly accurate measurements of pitch, roll, and yaw rate using three rate gyros, as well as x, y and z acceleration via three accelerometers. The CAN-based unit is temperature compensated and has improved calibration and stability.

It is designed for use either as a standalone sensor with simple connection and configuration via the CAN bus interface, or for use with VBOX GPS data loggers.

When used in conjunction with VBOX 3i, data from the IMU can be seamlessly integrated with GPS to produce pitch and roll angle accurate to 0.06˚ (RMS) as well as smoother velocity data. This ensures GPS data even when satellite reception is interrupted.


Yaw Rate Sensor (RLVBYAW03) 

VBOX Yaw Rate Sensor (RLVBYAW03) is an advanced vehicle yaw rate sensor with integral accelerometers. The accelerometers are mounted in the X and Y plane for measurement of lateral and longitudinal acceleration.

The Yaw Rate Sensor is constructed with a splash proof casing, which is rated to a limited ingress IP rating of IP65, making it ideal for use on boats or in harsh environments.

Using synchronous 24 bit sampling for each of the internal sensors provides a high degree of accuracy with yaw rate resolution typically 0.01 degrees per second and acceleration resolution down to 0.001 g.

The Yaw Rate Sensor is designed for use with the Racelogic VBOX range of GPS data acquisition systems or as a standalone sensor with simple connection and configuration via the CAN bus interface.
