Spirent brings realistic GNSS simulation to vehicle hardware-in-the-loop testing

0

Spirent Communications, specialists 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.  

Martin Foulger, general manager of Spirent’s positioning, navigation and timing business says, “With our SimHIL software and GNSS simulators, test engineers can bring realistic, controlled GNSS simulation to their HIL testing environments – a vital requirement in a world where ADAS features are relying more heavily and critically on accurate positioning.” 

Spirent has worked with leading suppliers to ensure SimHIL is compatible with their HIL platforms and because of its open API, there’s broad scope for additional custom third-party integrations. 

Ricardo Verdeguer Moreno, product manager for connected and autonomous vehicles at Spirent, adds, “When used with our GSS7000, SimHIL latency is less than 40ms from motion command to RF output and supports all GNSS and SBAS signals. 

SimHIL is also compatible with all the options and features available in Spirent’s GNSS simulators, including ionospheric and tropospheric modelling, antenna patterns, date and time settings, and obscuration and multipath effects via Sim3D.”
