Automotive GNSS test and simulation solution

Dspace and Spirent join forces to provide integrated automotive test solutions

  • Spirent Communications and Dspace have entered into a technology partnership aimed at enhancing the realism of real-time positioning scenarios used by hardware-in-the-loop (HIL) test systems in autonomous driving applications.

The aim of this collaboration is to offer a turnkey solution by combining Dspace’s AD-HIL solution with Spirent’s GSS7000 range of satellite navigation systems (GNSS) simulators.

This solution should enable developers of autonomous driving systems to validate the behaviour of vehicles in critical location scenarios using real satellite signals, with all the tools pre-integrated by a single supplier.

Spirent’s GSS7000 solution supports a variety of Global Navigation Satellite Systems (GNSS): GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS.

According to Dspace, increasing levels of driver automation and the responsibility that this places on manufacturers means that the accuracy and latency of GNSS systems are becoming increasingly critical, particularly for SAE levels of driver automation at Level 3 or beyond.

Combined with Dspace’s AD-HIL simulation interfaces with radar, camera, lidar and ultrasonic sensors, Spirent’s GSS7000 series simulator, with its high-resolution maps and low-latency response, becomes an additional tool operating in parallel for the validation of driver assistance algorithms. Jamming and spoofing scenarios can be validated as functional safety tests for autonomous platforms, while Spirent’s SimHIL software interface ensures reliable communication between each partner’s systems.
