ADAS Testing Just Got Easier

Dedicated ADAS testing

Building on the key features that made VBOX 3i the industry standard data logger for automotive testing and validation, VBOX 3i ADAS has taken the evolution of this family of data loggers and created a whole new species dedicated to ADAS testing.

Outstanding Accuracy

The VBOX 3i ADAS GNSS receiver, which is multi-constellation and dual frequency, delivers outstanding RTK signal reacquisition and resilience, ensuring you spend more time logging RTK accurate data on both the test track and the open road.

Easy Set-up

You can fully customise ADAS test setups, with the vehicle under test able to simultaneously reference any combination of up to five moving and static targets, three road-line references and 99 signposts. Tests requiring multi-target and multi-lanes can be easily configured to validate ADAS systems.

The VBOX 3i ADAS offers Euro NCAP-compliant logging rates (100 Hz) and a positional accuracy of less than 2 cm, when used with an RTK Base Station or NTRIP device.

The latest RTK, multi-constellation GNSS receiver delivers centimetre-level accuracy with robust signal reliability even in challenging GNSS environments.

VBOX 3i ADAS has the ability to utilise data from a VBOX IMU and uses a Kalman Filter to improve all parameters measured in real-time at 100 Hz.

Connect to a laptop or tablet via USB, Bluetooth or Serial for real-time display and analysis of test data in the field.

Log up to 32 channels directly from the vehicle’s CAN bus.

Evaluate the full range of ADAS scenarios with customisable parameters and intuitive data analysis in VBOX Test Suite software.

Intuitive Setup Software for Complex ADAS Scenarios

The test configuration process has been significantly improved, with all configurations and file management now conducted in VBOX Setup (instead of VBOX Manager).

Smart illustrations, active guidance and instantaneous feedback give you the ability to see your configuration as it comes together and easily make corrections if necessary.

RTK Positioning Correction Service

We offer flexible options to access the Topnet Live GNSS Positioning Correction Service within Europe with the purchase of any RTK enabled VBOX test solution.

Test in areas with poor satellite coverage

VBOX 3i ADAS offers IMU integration, which means you can reliably test in areas with limited or no satellite coverage, such as tunnels, deep urban canyons and test tracks with heavy tree lining.

The VBOX 3i ADAS's GNSS receiver provides highly accurate measurements of position, velocity and distance in areas with a clear view of the sky. However, as you start to lose visibility of the satellites in built-up or obscured areas, the accuracy of the data typically starts to drift.

By combining wheel speed data from the vehicle's CAN bus with GNSS and Inertial data from a VBOX IMU, the VBOX 3i ADAS can maintain the accuracy of the estimated speed and position, even when you lose satellite signal.

The new IMU05

Data integration from the IMU05 is especially helpful when GNSS signal reception of the VBOX 3i (V5) is interrupted or weakened. In such cases, the VBOX 3i can still provide accurate information about position, velocity, and body angles, ensuring reliable data even when satellite signal reception is compromised.

Pitch & Roll Angle


Yaw Angle




The IMU05's precise measurements of roll, pitch, and yaw rate are obtained through three high-precision gyroscopes with an industry-leading bias stability of 1.2 degrees per hour. For those who need more precision, we offer the S model, IMU05-S, which utilizes MEMS high-precision gyroscopes with an even lower bias stability of 0.8 degrees per hour.

Which applications can you test with VBOX 3i ADAS?

You can validate the accuracy of almost any Advanced Driver Assistance System using a VBOX 3i ADAS, including Adaptive Cruise Control, Blind Spot Detection, Park Assist, AEB, Lane Keep Assist and Dooring. VBOX 3i ADAS provides Euro NCAP-compliant logging rates (100 Hz) and highly accurate measurements of position, speed, attitude, separation distance and time-to-collision data from multiple vehicles. 

Add-ons and Accessories

The VBOX NTRIP Modem allows a VBOX 3i RTK to receive positional correction data via Network RTK, without having to use a VBOX Base Station.

RACELOGIC ADAS radios for V2V communication, giving relative longitudinal and lateral distances to cm accuracy.

The VBOX DGNSS RTK Base Station is designed to improve positional accuracy by calculating and transmitting differential correction data.
The VBOX IMU provides highly accurate measurements of pitch, roll, and yaw rate using three rate gyros, as well as x, y, z acceleration via three accelerometers.

Straight or curved lane markings can be mapped out and plotted to cm-level accuracy when using this survey trolley kit alongside your VBOX 3i ADAS and RTK correction system. The survey trolley comes with a line mapping rover wheel, a custom rucksack, a radio antenna and a battery pack.

A set of audio and visual sensors designed specifically to test the required elements of Euro NCAP scenarios.

The VBOX CAN Hub doubles the number of vehicle CAN channels that can be logged with a VBOX 3i and also doubles the number of modules that can be used.
The VBOX Multi-Function Display is designed to show a large number of different variables and performance results on a clear backlit LCD display.
