The 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.
Aimed at high-precision positioning applications such as assisted and autonomous driving where centimetre-level accuracy is required, 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 fast time to first fix (Fast TTFF).
With its ability to concurrently receive signals from all GNSS constellations (GPS, GLONASS, Galileo, BeiDou) it is able to further improve performance by increasing the number of satellites that are visible at any given time.
To achieve centimetre-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.
Commenting Hamilton Chen, Country Manager, u-blox China said, “Offering centimetre-level accuracy, high security standards, and real-time kinematics, u-blox F9 is ideal for any ADAS or autonomous driving application.”
