The Global Navigation Satelite System is used for geospatial positioning all over the world. It allows electronics chips to determine their locations using high precision time and signal analysis. Autonomous systems totally depend on these types of navigation chips for positioning. However, some of the present navigation chips lack accuracy.

U-Blox has launched a new navigation chip ZED-F9K based on the GNSS navigation system. The company states that it provides high accuracy positioning up to decimeter level which helps automotive vehicles for high performance.

GNSS high accuracy positioning

ZED-F9K supports multiple channels of up to 184 which helps in improving accuracy in positioning. This module can easily integrate with any microcontrollers or processors that are capable of I2C, SPI, and UART.


It also features low convergence time, which can be as low as 10 seconds. This requires a nominal operating voltage from 2.7 V to 3.6 V with a power consumption of 250mW.

This module reaches the high navigation output rate of up to 30Hz. The company informed that it is ideal for innovative automotive architecture designs with less space and power.

Integrated sensors with less technical risks

Inbuilt high sensitive IMU sensors help to improve navigation experience to the users and also sophisticated built-in algorithms fuse with IMU data, GNSS measurements, and vehicle dynamic model provides lane accurate position.

This module provides precision locations to navigation applications like autonomous vehicles. This device provides a fewer risk of failures because of its inbuilt architectural design for positioning.
