Spirent is driving the future of autonomous vehicles

Real-world, real-time GNSS performance testing

Global Navigation Satellite System (GNSS) plays a core role in today’s autonomous vehicle technology. Developers must put a vehicle through millions of miles of testing, which is even more critical when testing smart safety features in multiple types of locations and places on Earth. This means testing in the lab is critical. Spirent is the global leader in GNSS test and assurance solutions.

Fundamentals of GPS Threats

Satellite navigation signals are weak and can easily be blocked, damaged or compromised, including malicious faking of GPS signals, and impact your critical systems. As industries such as automotive rely more on Global Navigation Satellite System (GNSS) signals and data, there’s an urgent need to keep pace with emerging threats. Spirent can advise on any aspect of GNSS threat identification, testing and risk mitigation.

Create a realistic GNSS test environment in the lab

You need to know how your GNSS enabled device will perform in the real world. But testing in the real world is not feasible due to time and cost constraints. Every element of your test environment can have an impact on the realism of your testing, from the components used in your test equipment through to the software tools used to enhance the virtual environment. Learn the value of creating a realistic GNSS test environment in the comfort of your own lab.

If an autonomous vehicle can’t receive GNSS signals (or receives inaccurate signals), it could result in a vehicle miscalculating its position on the road, making unsafe manoeuvres and potentially putting passengers, pedestrians and other road users at risk.

How to choose a GNSS simulator

Simulation is the primary tool for testing GNSS enabled equipment. However, selecting the right simulator is not simple. You need to establish if the simulator performs as expected, failure could have catastrophic consequences for your product, and even your business. Explore some of the important performance characteristics you need to consider and can make the difference between success and failure.

Spirent brings realistic GNSS signal simulation into Italdesign’s vehicle testing lab

Part of the Volkswagen Group, Italdesign is a design and engineering company at the forefront of car development and production. To solve the challenges of finding a way to reliably test prototype models of connected and autonomous vehicles, Italdesign chose Spirent’s GSS7000 multi-constellation, multi-frequency simulator.

Testing the next generation of self-driving vehicles requires highly realistic modeling of multipath and obscuration effects as well as highly realistic and reliable HIL integration. Spirent helps GNSS test teams achieve maximum realism without sacrificing knowledge or control of the test environment.
