U-blox has released the ZED-F9K high precision multi-band GNSS module with built-in inertial sensors. The module consolidates the most current generation of GNSS receiver technology, signal processing algorithms, and correction services to deliver down within seconds to decimeter-level accuracy, addressing the ever-evolving needs of ADAS and automated driving markets.


The device's high precision dead reckoning module builds on the company's F9 technology platform. Compatibility with modern GNSS correction services improves even further the positioning accuracy by compensating ionospheric and other errors. The multi-band, multi-constellation RTK receiver module receives GNSS signals from all orbiting GNSS constellations. A bigger number of visible satellites grows positioning performance in partially obstructed conditions, while increased satellite signal diversity produces faster convergence times when signals are interrupted.


By robustly supplying lane accurate position information, the device meets the demands of ADAS and autonomous driving applications, as well as head units and advanced navigation systems. The device’s accuracy and low latency also make it excellent for automotive OEMs and Tier 1s developing V2X communication systems. By continuously sharing their location with other traffic participants, these systems add to improving overall road safety and decreasing traffic congestion.


“We designed the ZED-F9K to be a turnkey high precision GNSS solution that caters to the needs of today’s and tomorrow’s connected cars,” says Alex Ngi, product manager, Product Strategy for Dead Reckoning, u‑blox. “The ZED-F9K is unique in that it integrates a multitude of technologies, from the GNSS receiver to the inertial measurement unit and relevant dead reckoning algorithms into a single device for which we can ensure performance throughout the customer product development cycle.”
