Presentation

Position and navigation testing – chipset to full industrial vehicle testing

The use of GPS/GNSS for positioning and navigation has become a commodity. As the levels of vehicle navigation assistive systems and autonomy increase, particularly in industrial vehicles, so do the system requirements and functional dependability. This presentation reviews testing requirements and challenges for positioning and navigation systems that primarily rely on GNSS as their global positioning source. It explores how testing and validation across the different layers of the supply chain are used at various levels of design, development and production. The tests range from functional testing and scenario simulation to field testing and vehicle compliance.
