GNSS Testing for Connected Autonomous Vehicles

The safety critical applications of GNSS in CAV mean that, more than ever, OEMs and suppliers need to verify every development at every stage. From full HiL integrations through to high resolution record and playback, Spirent’s lab test solutions are perfectly suited for evaluating the performance, quality and reliabilty of the latest technologies - giving our customers performance and peace of mind.

Simple integration with SimGEN®

Here we demonstrate Spirent’s SimGEN suite integrating with IPG CarMaker, Oktal SE-NAV, and Microsoft AirSim to make the ultimate CAV testing solution.

Sensor Fusion Testing using HiL Simulation

Hybrid positioning and sensor fusion often require extensive testing to ensure the various data inputs are correlated accurately under real-world conditions. Increasingly, CAV developers are using HiL test setups to ensure systems interoperability. Spirent’s GSS7000 simulator, with industry leading positioning application software, is an ideal tool for supporting this. Find out more about Spirent's GSS7000 simulator.


Realistic 3D Models

GNSS positioning and navigation can be degraded in urban environments by multipath, and the error can increase considerably if not properly compensated. The use of 3D models is becoming the preferred solution as it enables greater flexibility and accuracy in both antenna position and signal propagation.


Capturing the Real-World RF Environment

Because of the slow and expensive nature of field testing, there is a powerful argument for replacing a significant proportion of it with an RF Record & Playback solution. This can enable high-fidelity recording of real-world environments, bringing them into the lab for repeatable testing and allows you to:

  • Record GNSS signals, Celullar (LTE), and WiFi
  • Capture obscuration, multipath, diffraction, and interference - accurately
  • Record IMU and CANoe data
  • Replay in the the lab to assist ADAS development or IVS testing

GNSS Vulnerabilities Testing

The low power of GNSS signals on Earth and the widely disclosed GNSS signal format bring vulnerabilities of signal jamming, atmospherics (scintillation and space weather), and location or time spoofing.
