Configuration - Racelogic VBOX 3iS Dual Antenna RTK Manual

4. Measure the Antenna to Ref/IMU Offsets. You can find more information on this here.
◦ Roof Mounted: If required, take data translation measurements in the X, Y and Z axes from centre of IMU.
This is by default set to 1 m directly beneath the IMU when Roof Mount is 'Enabled'.
◦ In-vehicle mounted: Measure the relative position from the top centre of the GNSS antenna to the top centre
of the IMU. You must measure all 3 axes, X, Y and Z.
5. After the IMU04 is connected, you can apply power to the VBOX 3iS.
6. Enable External IMU Integration and enter the Antenna to Ref/IMU Offsets. You can do this using the
VBOX Setup Software, the Front Panel of the unit, or with VBOX Manager.

Configuration

You can configure external IMU Integration via the
Manager.
Note: When mounting the IMU04 on an angle, the raw accelerometer and gyro data will be incorrect as these channels
are not pitch compensated.
IMPORTANT
The IMU04 must be in a Racelogic CAN mode to be used for IMU Kalman Filter.
