  • ADAS Mode - Select between the ‘ADAS Mode Disabled’ Kalman Filter, used for Brake Stops and general speed/attitude performance, and the ‘ADAS Mode Enabled’ Kalman Filter that is used for high accurate position.
  • Side facing down - Select the orientation of the VB3iS side facing down. This is only applied once the IMU menu is exited to the Main Menu. When the orientation is changed, the Kalman Filter is reset.
    Note: This option is only presented when the IMU Location is set to ‘Internal’.
  • Side facing forwd - Select the orientation of the VB3iS side facing forward. This is only applied once the IMU menu is exited to the Main Menu. When the orientation is changed, the Kalman Filter is reset.
    Note: This option is only presented when the IMU Location is set to ‘Internal’.
  • Pitch/Roll Offset
    • Auto Level - Begins the process of levelling the IMU calculated Pitch and Roll Angles. Once selected, the unit averages the pitch/roll angles over a 5 second period and will then subtract/add the averaged values to make the pitch/roll angle 0. This offset will be displayed on the main screen.
    • Clear - Clears the current pitch/roll offset values.
  • Gyro Offset
    • Auto Level - Begins the process of levelling the IMU calculated Pitch, Roll and Yaw Rates. Once selected, the unit averages the rates over a 5 second period and will then subtract/add the averaged values to make the rates equal to 0. These offsets will be displayed on the main screen.
      If the IMU location is set to External however an external IMU is not detected by the unit, an error message is displayed.

Warnings

If GNSS, RTK (either no RTK or RTK Float), IMU operation or Wheel Speeds (No Data) have an error, then the screen will flash one of the following appropriate screens (flashing warning triangle + text showing error):
 

VB3iS Display Warnings.png
 

The RTK messages will show only when an RTK Mode is Enabled and the following is true:

  • Standalone/solution type 1 = NO RTK
  • RTK Float/Solution type 3 = RTK Float
  • RTK Fixed/Solution type 4 = OK

Kalman Filter

If IMU Integration is Enabled, the main screen should show an indication of the Kalman Filter status.

Once Sat lock has been acquired (and RTK fixed if enabled), the display will read 'Filter Initialising - Remain Stationary for 30s'.
 

The message will then countdown to 0 seconds before displaying 'Stationary Initialisation Complete' for 2 seconds before displaying 'Waiting For Movement'.

If at any stage during the above the speed rise above 0.8 km/h, the countdown and filter initialisation will reset and the following message displayed 'Speed>0.8kph – Initialisation reset'.
