Turnkey solution reduces effort needed for decimeter-level positioning accuracy

U-blox recently announced that Siemens has integrated their ZED-F9K high precision dead reckoning module into its Toyota Prius V2X test fleet.

As the only current source of absolute position, the satellite-based positioning performs a critical role in ADAS and driverless vehicles. The same is true in V2X communication, in which these vehicles continuously share their position and information with other traffic participants – cars and pedestrians – as well as surrounding infrastructure, advancing road safety and decreasing traffic congestion.

V2X test vehicles typically determine their position employing high-end, expensive GNSS receivers. While these give highly accurate position information, they fail to realistically portray the hardware that will be used in vehicles created for the mass market. By choosing to use the ZED-F9K turnkey solution for high precision dead reckoning, the company was able to align the performance of their test fleet with real world conditions while also decreasing the expense and the engineering energy needed to develop their vehicles.

“We’ve had a very positive experience with U-blox’s ZED-F9K high precision dead reckoning solution. The product delivered strongly from the initial design-in to the data and performance in our first tests,” says Igor Passchier, engineering fellow, Connected and Automated Driving at Siemens PLM Software. “It underscores the reputation of U‑blox as a trusted innovator in GNSS technology.”

“Our collaboration with Siemens shows the extent to which the ZED-F9K turnkey solution saves OEMs time, cost, and engineering effort while providing decimeter-level positioning performance,” says Alex Ngi, product strategy for dead reckoning, Product Center Positioning, U-blox. “For us, it has also been a welcome opportunity to contribute to solving the challenges in the autonomous driving ecosystem.”
