Spirent Communications , a leader in global navigation satellite systems (GNSS) testing solutions, has announced the release of SimHIL, an integrated hardware-in-the-loop (HIL) testing software API for Spirent GNSS simulators. SimHIL brings high fidelity GNSS signal simulation with low latency to automotive industry HIL testbeds.

Spirent’s SimHIL software has been developed to meet the automotive industry’s growing need for realistic positioning, navigation and timing testing for sensor fusion. As customers apply increasing pressure on car manufacturers for more advanced driver-assistance system (ADAS) features and advanced infotainment systems, test labs need to be able to combine Wi-Fi, camera, lidar, radar, inertial and GNSS data that power these advanced automotive systems.

SimHIL helps test engineers bring accurate, controlled and coherent data from GNSS and inertial sensors to their sensor fusion algorithms within HIL test environments. Facilitating the ultra-low latency, complete control, enhanced realism, and ease of use and setup of Spirent GSS7000 and GSS9000 GNSS simulators, SimHIL is an ideal solution for OEMs and tier-one suppliers developing ADAS, V2X and sensor fusion engines.

The new SimHIL API enables:

  • External motion input –real-time direct motion and trajectory data input from simulators.
  • Sensor fusion – introducing GNSS signals into sensor fusion engines.
  • V2X testing – validation and performance benchmarking of V2X applications.
  • Infotainment system testing – real-time scenario feedback to system and driver responses.
  • Vehicle-in-the-loop (VIL) – final production form product testing.
  • Accurate testing – reliable results supported by ultra-low latency simulation. Criticality of ADAS features, such as lane assist and automatic braking, mean that 3+ metres of uncertainty introduced by higher latency systems is not sufficient.
