Segmentrio's GPS/GNSS technology helps improve road efficiency/safety

Belgium builds an intelligent highway testing environment with the assistance of Septentrio high-precision GPS/GNSS technology

Recently, Belgium has launched a remarkable innovative project - an intelligent highway testing environment. As a key technology partner in this project, Belgian company Septentrio has integrated its high-precision GPS (Global Positioning System)/GNSS (Global Navigation Satellite System) receivers into the vehicles and infrastructure of the testing environment, aiming to provide reliable and high-precision positioning information for autonomous vehicles and truck fleets, and promote the application of sensor fusion technology.

Septentrio's advanced GPS/GNSS receiver is a key component of the Belgian Smart Highway system. A section of the highway in the test environment will be used as a technical test site to verify the performance of autonomous vehicle and truck fleets under real road conditions and prepare for future large-scale deployment.

By integrating Septentrio's GPS/GNSS receiver, the intelligent highway system can ensure precise communication between vehicles and between vehicles and infrastructure. When vehicles can understand each other's positions and speeds in real time, they can coordinate driving more effectively, reduce traffic congestion, and improve road efficiency. Meanwhile, by detecting deceleration driving in advance and automatically braking, the intelligent highway system can significantly improve driving safety and reduce accident risks.

In order to further improve positioning accuracy, roadside units along the intelligent highway will be equipped with GNSS receivers as reference stations, continuously emitting corrected positioning signals. The onboard GNSS unit will use this calibration information and built-in quality indicators to calculate positioning data below decimeters, providing unprecedented accuracy for "smart cars". In addition, these receivers can provide accurate time information to ensure that the numerous sensors on the vehicle can work synchronously, achieving more efficient collaboration.

It is worth mentioning that Septentrio's GPS/GNSS receiver adopts advanced interference suppression (AIM+) technology, which can effectively prevent illegal interference devices from interfering with GPS signals. On highways, some trucks are equipped with such interference devices to evade road tolls, which can interfere with the normal use of GPS signals by other vehicles and technical facilities. However, Septentrio's receiver, with its excellent anti-interference ability, can ensure stable and reliable positioning services in complex environments.

This intelligent high-speed project has received strong support from the Flemish government and is closely collaborating with the world-renowned Nanoelectronics and Digital Technology Research and Innovation Center Microelectronics Research Center (IMEC). In addition, the project has also attracted industry giants including Toyota, Ericsson, and Telenet as partners, as well as research institutions such as the University of Antwerpen and UGent. This cross-border cooperation will inject strong impetus into the research and application of intelligent highway systems, promoting the rapid development of autonomous driving technology.
