Setting up GPS Start/Finish Lines using VBOX 3i RTK


Instead of using a laser light barrier to trigger the start of the Pass-By Noise test, a VBOX 3i RTK (VB3iDR) can be used to set the start and finish lines when used with an RTK Base Station or NTRIP solution. This means that the test vehicle does not have to come to a stop between test runs.
