Automotive ADAS

The automotive industry is on the move. We want cars cleaner, safer, smarter. This is driving change in the industry on many fronts, one of which is: ADAS (Advanced Driver-Assistance Systems). ADAS helps the driver control the car resulting in improved comfort and safety. Development of driver assistance technologies is paving the way towards full vehicle autonomy.  

The numerous sensors aboard the car such as radars, LiDAR and cameras take the role of human eyes as vehicle’s ‘perception’. Together with artificial intelligence, perception provides the vehicle with awareness of its surroundings and obstacles, both static and dynamic, expected and unexpected. Another crucial part of ADAS is the information about the global location, speed and orientation of the vehicle. High-performance GPS/GNSS receivers are accurate and safe enough for automated driving and, together with an inertial sensor, they complement vehicle’s perception. Take a look at our Automotive insight article to find out how GNSS and perception sensors complement each other for optimal autopilot performance. 

Septentrio provides reliable and robust centimeter-level positioning for safe automotive localization by utilizing its expertise in multi-frequency GPS/GNSS technology.  

Centimeter accuracy for lane-level navigation  

SSR (PPP-RTK) Corrections and PPP Corrections enable multi-frequency GNSS receivers to calculate the position with centimeter-level accuracy.  

GNSS/INS for increased reliability and availability  

Our GNSS receivers can work together with inertial measurement units to extend positioning reliability and availability in difficult environments and to provide 3D vehicle orientation.    

Integrity and robustness 

But how can I be sure that my autopilot can rely on GPS/GNSS positioning? The answer lies in monitoring the receiver’s integrity indicators. By outputting the uncertainty of the current position, the receiver indicates to the ECU whether it is safe or not to execute the planned maneuvers.  

Septentrio receivers come with built-in Advanced Interference Mitigation (AIM+) technology, offering best-in-class security against radio interference, jamming and spoofing.  

Tried, tested and true  

Other safety-of-life applications such as aviation have already been using GNSS for decades. One of the reference networks implementing Septentrio receivers is the EGNOS network, which provides corrections for airplane approach and landing guidance systems.
