Spirent Communications has announced the role of its positioning, navigation and timing (PNT) simulation systems in the creation of a new automotive positioning standard in China.
The new GB/T 45086.1-2024 standard sets out the recommended technical requirements for onboard vehicle positioning systems such as GNSS. It is expected to be adopted as part of China’s Accident and Emergency Calling Systems (AECS) framework.
Spirent’s expertise and simulation technology were instrumental in assisting with the development of the new GB/T standard. “Regulating the performance of PNT, particularly GNSS, is a hugely important topic across a range of industries and technologies and it’s great to see China taking steps to accelerate the implementation of robust and precise systems,” said Adam Price, Spirent’s vice president of PNT simulation.
The introduction of this latest GB/T standard marks a moment for automotive sector safety and positioning accuracy. It is expected to underpin the forthcoming AECS framework, which will become a regulatory requirement for all vehicles sold in China from next year. As China’s equivalent to the European eCall, AECS will ensure rapid response in car accidents, potentially saving lives. The new standard aims to enhance the reliability and performance of these positioning components, and it also has the potential to provide the groundwork for regulation of AVs on public roads.
In addition to Spirent technology and expertise supporting the development of this new positioning standard, major test houses in China use Spirent simulators and test scenarios to qualify positioning capabilities. These include Tianjin Automotive Test Center (TATC), China Automotive Engineering Research Institute (CAERI), and National Automobile Quality Supervision and Test Center (NAST).
