This mode can be used with Automatically Commanded Steering Function (ACSF)/ Lane Change tests and facilitates the ability for vehicle separation parameters to be calculated at the Subject vehicle with respect to 3 Target vehicles.
This system consists of a VB3iD-RTK in each Target vehicle and a VB3iD-RTK in the Subject vehicle.
High accuracy of the vehicle separation calculations is made possible by the use of a Static Base Station or NTRIP correction solution.
An NTRIP solution removes the need for a fixed Base Station to obtain accurate GPS position, thereby allowing vehicle separation testing to be carried out in real world environments and without the restrictions of Base Station radio range.
The Target VBOXs (tracked vehicles) will also log the normal GPS data to a .vbo file, so that the files from each VBOX can be compared in the VBOX Tools Graph screen or VBOX Test Suite Chart screen. This is useful to see the relative positions.
Configuration of the VBOX is done through VBOX Manager (RLVBFMAN).
