The Moving Base test solution allows engineers to test ADAS applications on the open road. It works by linking two VBOX 3i RTK units, with the system in the subject vehicle transmitting corrections to the target vehicle at an update rate of 20 times per second.
This replaces the need to implement an RTK Base Station with a limited broadcast range, and provides engineers with the ability to test on normal roads, over reasonable distances, among other road users and roadside furniture, to under 5 cm relative positional accuracy.
The accuracy is enhanced by employing signals from the Russian GLONASS constellation as well as a method which uses refined delta positions obtained from carrier phase measurements. This reduces the noise levels of pseudo-range measurements (raw distances to each satellite) and removes positional jumps.
