u-blox announced that smart electric vehicle manufacturer, Xpeng Motors, has selected u-blox’s F9 high precision GNSS (GPS, GLONASS, Galileo, BeiDou) technology for use in its P7 long range sports EV sedan.

u-blox F9 has been incorporated into the vehicle’s XPILOT 3.0 advanced driver assistance system (ADAS) used for navigation-guided driving, automated parking, and autonomous driving. For example, once a navigation destination is set on a specific highway, the P7 will follow the route guidance to execute autonomous lane changing, switching to high-speed routes, and selecting the optimal route in real-time.

Per the company, the u blox F9 platform uses GNSS signals in multiple frequency bands (L1/L2/L5) to correct positioning errors caused by the ionosphere and deliver ideal time to first fix (TTFF). Its ability to receive signals from all GNSS constellations (GPS, GLONASS, Galileo, BeiDou) improves performance by increasing the number of satellites that are visible at any given time. To achieve centimeter-level accuracy, u-blox F9 also uses a multi-band real-time kinematic (RTK) feature that measures the phase of each signal in addition to the clock data. An RTK update rate of up to 20 Hz is possible.

The u blox F9 platform sets a high standard for security with built-in jamming and spoofing detection systems that protect against intentional and unintentional interference. Dead reckoning technology based on inertial sensors extends high precision performance to otherwise challenging urban environments.
