PProduct SummaryZED-F9K
High precision dead reckoning with integrated IMU sensors

Standard

Continuous lane accurate positioning under the most challenging conditions• Decimeter level accuracy for automotive mass markets• Ideal for ADAS, V2X and head-up displays

Professional• Turnkey multi-band RTK solution with built-in inertial sensors• Low latency position update rate of up to 30 HzAutomotive

17.0 × 22.0 × 2.4 mm

The ZED-F9K module with the u-blox F9 multi-band GNSS receiver features rapid convergence time within seconds. Thismass-market component provides decimeter-level positioning with high availability, while making use of all four GNSS
constellations simultaneously.
It is the first dead reckoning module with an integrated
Inertial Measurement Unit (IMU) capable of high precision
positioning. The sophisticated built-in algorithms fuse theIMU data, GNSS measurements, wheel ticks, and vehicle
dynamics model to provide lane accurate positioning whereGNSS alone would fail. The module operates under open-sky
motorways, in the wooded countryside, in difficult urban environments, and even in tunnels and underground parking. Inmodern automotive applications, such as Advanced Driver
Assistance System (ADAS) where availability can improve thesafety of our roads, ZED-F9K is the ultimate solution.
The device is a turnkey solution eliminating the technical riskof integrating third party libraries, precise positioning engines,
and the multi-faceted hardware engineering aspects of radio
frequency design and digital design. The u-blox approach provides a transparent evaluation of the positioning solution andprovides clear lines of responsibility for design support, while
reducing supply chain complexity during production.
ZED-F9K is ideal for innovative automotive architecture
designs with limited space and power. The module provides
accurate location services to the increasing number of intelligent Electronic Control Units (ECU), such as telematics
control units, navigation systems, infotainment, and V2xsafety systems.
The module reaches a high navigation output rate of up to30 Hz. The on-board processor augments fused GNSS position with additional IMU-based position estimates. Drivers
experience responsive, lag-free user interfaces. ZED-F9K canoutput raw IMU and raw GNSS data for advanced applications.
ZED-F9K modules are manufactured in ISO/TS 16949 certified sites and are fully tested on a system level. Qualification
tests are performed as stipulated in the ISO 16750 standard:“Road vehicles – Environmental conditions and testing forelectrical and electronic equipment”.
