New GNSS Simulation Tool For Self-Driving Automotives


  • AVL’s Driving Cube is designed to enable reproducible testing of driver assistance systems
  • It provides integration with satellite navigation systems including GPS, Glonass, Galileo, BeiDou, QZSS and SBAS 

Self-driving vehicles are cars or trucks in which human drivers are never required to take control to safely operate the vehicle. Also known as autonomous or “driverless” cars, they combine sensors and software to control, navigate, and drive the vehicle.

AVL and Rohde & Schwarz have collaborated to develop a test environment for autonomous vehicles. It enables the reproduction of realistic GNSS reception conditions. AVL’s Driving Cube is designed to enable reproducible testing of driver assistance systems.

Create a virtual environment


It enhances driving features for self-driving vehicles using a real vehicle in a virtual environment. Test drives are performed with a real vehicle. The measurement devices used for the test drives are chassis dynamometer and powertrain testbeds.

These virtual driving scenarios can test a vehicle’s peripheral sensors, control systems and actuators. The vehicle’s receiver is stimulated using signals generated on the testbed. This can help in creating a virtual environment on how sensors, automated driving features and other actuators respond inside the vehicle.

Works for L1, L2 and L3 frequency bands

Rohde & Schwarz GNSS stimulators are used (SMBV100B or SMW200A) in developing the system. It allows the generation of signals for all of the available satellite navigation systems. These systems include GPS, Glonass, Galileo, BeiDou, QZSS and SBAS systems. It can work across all frequency bandwidths including L1, L2 and L5 bands. This makes them suitable for testing multi-frequency receivers. These receivers play an important role in automated driving.

Extensions for integrating AVL Driving Cube

According to the company, the stimulators form a modular system that can be integrated into the test environment. The stimulator is controlled automatically from the simulation platform. R&S’s have provided extensions for AVL Driving Cube. These can be integrated with the driving modules for quick diagnostics.

Dr Tobias Düser, head of advanced solution lab at AVL Deutschland GmbH says

“In Rohde & Schwarz, we now have a strong and reliable partner for GNSS stimulation. By generating consistent GNSS signals in connection with environment simulation, AVL Driving Cube now provides a test system that allows users to validate GNSS-based driver assistance systems and autonomous driving features.”
