10. The VBOX 3iSL will now use the inertial data transmitted by the connected IMU and integrate it with the

GPS data to generate filtered and smoothed data speed, heading and position data.

NB: If no IMU is currently connected, the data logged by the VBOX 3iSL will be the raw unfiltered GPS

data. If however an IMU is connected after the VBOX 3i has begun to log data the file will contain a mix

of unfiltered and filtered data.

11. Once the VBOX 3iSL has been set up to use the IMU data it will automatically log to CF card the Speed

Quality, IMU Kalman Filter Status and IMU channels.

These channels allow Racelogic to troubleshoot any problems that may be encountered with the

Kalman filter generated data and cannot be switched off.
