Unique and caters to the needs of today’s and tomorrow’s connected cars

u-blox, a global provider of leading positioning and wireless communication technologies, has announced the u‑blox ZED-F9K high precision multi-band GNSS (Global Navigation Satellite System) module with built-in inertial sensors. The module combines the latest generation of GNSS receiver technology, signal processing algorithms, and correction services to deliver down to decimeter-level accuracy within seconds, addressing the evolving needs of ADAS (Advanced Driver-Assistance Systems) and automated driving markets.

The ZED-F9K high precision dead reckoning module builds on the u‑blox F9 technology platform. Compatibility with modern GNSS correction services further improves positioning accuracy by compensating ionospheric and other errors. The multi-band, multi-constellation RTK (Real Time Kinematics) receiver module receives GNSS signals from all orbiting GNSS constellations. A greater number of visible satellites improves positioning performance in partially obstructed conditions, while increased satellite signal diversity delivers faster convergence times when signals are interrupted.

It continues to deliver lane accurate positioning when satellite signals are partially or completely obstructed as is the case when the vehicle is in parking garages, tunnels, urban canyons, or forested areas. When satellite signals become available again, the module combines inertial sensor data with GNSS signals to deliver fast convergence times.

Key Features

  • Decimeter-level accuracy
  • Inertial sensors into the module constantly monitor changes in the moving vehicle’s trajectory

The result of this combination of the latest developments in GNSS technology, correction services, and inertial sensing is a tenfold increase in positioning performance over standard precision solutions.

By robustly providing lane accurate position information, the ZED‑F9K meets the needs of ADAS and autonomous driving applications, as well as head units and advanced navigation systems. The module’s accuracy and low latency also makes it ideal for automotive OEMs and Tier 1s developing V2X (Vehicle-to-everything) communication systems. By continuously sharing their location with other traffic participants, these V2X systems contribute to increasing overall road safety and reducing traffic congestion.
