Saving and Loading Corner Positions
Once corner positions have been set in VBOX Manager they can be saved as a .vbc file and recalled later for
repeatability.
Note: For corner positions to be recalled accurately, the GPS antenna location on the car and the location of the
Base Station GPS antenna must be identical as when the data was recorded.
1. Within the 'CORNER POS' option of the 'ADAS' menu select 'SAVE'.
2. Within the 'SAVE' menu select the appropriate file name. This will be saved onto the CF card as a .vbc file.
3. To load a .vbc file containing offset data, select the 'LOAD' option from the 'CORNER POS' menu. This will
present a list of saved .vbc files containing corner position offsets. Selecting the appropriate file loads these values
into the VB3iSL-RTK firmware and allows for range values to be calculated to these corner positions.
Heading Smoothing
There are two configurable variables linked to heading smoothing; 'Smoothing Distance' and 'Speed Threshold'. Due
to the nature of the vehicle separation measurement and calculation process many channels are derived using the
heading of the vehicle which can be noisy. To overcome this heading can be smoothed with a dynamic smoothing
routine.
Under the 'LANE DEP' option within the 'ADAS' menu, select 'SMOOTHING'.
