Automotive: ADAS Development and Testing

Designing, testing and validating Advanced Driver Assistance Systems (ADAS) can be challenging because of the need to share detailed information about multiple vehicles in real-time. This is especially true when you consider the computational load and the time-constraints placed on the system.

OxTS products overcome these problems. By combining our widely used RT sensors with our RT-Range devices, you can quickly create a real-time network capable of tracking multiple targets with up to 1 cm accuracy. Precise and reliable information about each object’s orientation, velocity, range, acceleration is also available. The system can track vulnerable road users such as cyclists and pedestrians, up to 4 vehicles as well as fixed objects—providing accurate information about each of their relative positions over distances up to 1 km.

116_RT2500RT2000 Family The RT2000 family combines precision angular rate sensors and navigation grade accelerometers, a low cost GNSS receiver and an advanced navigation computer to form an inertial navigation system aided by GNSS in one very compact box. The RT2500 is the perfect way to step up from a GNSS receiver and benefit from inertial technology.

116_RT3000RT3000 Family The RT3000 family combines precision angular rate sensors and navigation grade accelerometers, a survey grade GNSS receiver and an advanced navigation computer to form an inertial navigation system aided by GNSS in one very compact box. A high speed GNSS update rate means the RT3000 is ideal for high dynamic tests.

116_RT4000systemRT4000 Family The RT4000 is a high-speed version of the RT3000 family of products. It has all the features of the RT3000 but has a 250 Hz update rate.



RT-Range S The RT-Range S is used for two functions: accurate (3 cm) measurement of the relative motion between two vehicles and precise (2 cm) measurement of lane position. The RT-Range S is used with one or two RT3000 or RT2002 Inertial and GPS Navigation Systems. All measurements are online, in real-time and output on a CAN bus.



RT-Base GPS Base Station To get the most from inertial and GNSS navigation systems it is often essential to have differential corrections or DGPS. The RT-Base is a differential correction system with an integrated battery and radio link packed in to a rugged, outdoor Peli case. It is configured to work seamlessly with the RT3000 and RT4000 family of products and can also be used by many other GNSS receivers.

116_90_GPSBaseNew GPS-Base Base Station The GPS-Base is a small, portable GPS base station capable of providing Differential Corrections for Differential GPS Receivers. The GPS-Base can be used with the RT3000 and RT4000 products to give up to 2 cm positioning accuracy.


116_RTBackpackRT-Backpack The RT-Backpack, an additional component for the RT-Range systems, represents a turnkey solution for tracking the position of pedestrians relative to a moving vehicle.


116_RTAnaRT-ANA 16-channel/16-bit Analog Output option Analog Outputs allow the connection of RT3000 family products to older data acquisition systems, to get simple measurements made fast. Analogue Outputs also offer the ability to get back to basics, to view signals directly on an oscilloscope. The RT-ANA product offers 16 separate channels of 16-bit analog accuracy.

116_84_RT-UPS1  The RT-UPS is an uninterruptible power supply for the power protection of all OxTS RT and Inertial+ systems as well as any other electrical or electronic devices that rely on continuous power supply.


116_rtmount RT-Strut, Fast Car Installation Kit The RT-Strut is an installation kit for putting the RT products in to a car quickly. The RT-Strut provides a rigid installation, close to the Center of Gravity (COG), and can be mounted in minutes.


When testing ADAS systems with the RT-Range, the distance between vehicles can now be extended to 1km with the new RT-XLAN. The RT-XLAN is a long range radio that extends and improves the data integrity and communication between vehicles. The extended range is especially useful on larger test tracks and for ADAS tests where vehicles need to communicate reliably over a longer distance.

Collision avoidance testing
Constant updates about the relative distance, velocity and acceleration of target vehicles and the ability to log data from the test vehicle’s CAN bus provide all the information you need for collision avoidance testing.

Radar, Lidar and vision qualification
Target vehicles defined as 8-sided polygons help test and validate radar systems, while feature-point technology allows the co-ordinates of up to 65,000 individual objects to be defined within the RT‑Range S—which are detected if they enter the sensor’s defined field of vision.

Balloon car testing
Static and mobile targets can be defined within the RT‑Range S, making it ideal for ADAS testing with balloon cars. When inflatable cars are defined as static targets, the system provides real-time measurements relative to the inflatable vehicle. For towed-targets, the polygon target is easily defined behind the towing car.

Adaptive cruise control testing
The RT‑Range S logs and provides real-time information about the relative position, velocity and bearing of other vehicles when testing adaptive cruise control systems. Using an integrated scanning system, real-world tests can even be carried out with un-instrumented target vehicles.

Testing lane departure warning systems (LDW)
The ability to map up to 8 lanes and display real-time information about where and how vehicles are moving within those lanes, as well as tracking other vehicles makes the RT‑Range S one of the leading solutions for testing LDW systems.

Testing forward collision warning systems (FCW)
Real-time updates on range, velocity and bearing mean the main test vehicle has a clear picture of where other targets are in relation to it. CAN bus data from the test vehicle can also be fed into the RT‑Range S, allowing quick analysis of relevant data once a test is completed.

Autonomous emergency braking systems (AEB)
Because target vehicle perimeters can be defined with up to 8 polygons and position is calculated in real-time with 2 cm accuracy, the RT‑Range S provides an accurate picture of where targets are in relation to it when testing AEB systems.

Blind-spot detection testing
The RT‑Range S maintains a precise picture of the target vehicles it is tracking, providing the information you need to test and validate blind-spot detection systems. The ability to simultaneously capture data from the vehicle’s CAN bus and compare it within one software package also saves time.

Full beam headlight management testing
When an RT‑Range S is used in conjunction with the new X-LAN antenna, reliable real-time information can be gathered from test vehicles up to 1 km away. As well as providing information on distance, bearing and the velocity of target vehicles, the RT‑Range S can also calculate visibility past other vehicles.

Autonomous vehicle development
Accurate 1 cm position measurements combine with precise velocity and orientation information, to provide a complete real-time picture of defined targets around the test vehicle. The RT‑Range S’ ability to generate position updates even during GNSS black-out also makes it suited to autonomous vehicle development.

Sign-post recognition testing
In order to test optical recognition systems, the location of up to 65,000 signs can be uploaded to the RT‑Range S. Our system then constantly evaluates any signs that fall within the defined sensor field of view and provides real-time feedback that can be used to evaluate on-board optical systems.

NHTSA FCW, LDW legislative tests
The RT‑Range S is already widely respected and used during NHTSA FCW tests and complies fully with the requirements laid down. It is also easy to install and use, and is cost-effective as it can also be used for many other tests in addition to FCW and LDW tests.

EU AEB legislative tests
The RT‑Range S meets all the requirements of the EU AEB test and is already widely used. It is easy to install and operate, and when combined with the X-LAN system, reliable communication can be achieved at ranges of up to 1 km.


The RT-Range is feature packed, making it the most comprehensive ADAS test solution by far. Here is a list of the features we have added.

Rear-end collisions are the most common types of accidents. The causes range from inattentiveness when the car in front slows or stops; distractions such as mobile phones, eating or adjusting the radio; poor visibility; inadequate distance etc. While most rear-end collisions in city traffic mostly result in minor vehicle damage, collisions on the motorway often result in serious or fatal injuries. ADAC, Europe's largest motoring organisation, has conducted extensive research into advanced emerge...
