Plenty of different functions can be configured on the ZED-F9K: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc.

U-blox based GPS products are configurable using the popular, but dense, Windows program called u-center. One SMA connector is included for a secure connection to an antenna. The breakout board has five communications ports, four of which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3V TTL), UART2 for RTCM reception (with 3.3V TTL), I 2C (via the one Qwiic connnector or broken out pins), and SPI. The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time. This reduces the time-to-first fix from a cold start (~26s) to a hot start (~2s). The SparkFun ZED-F9K GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZED-F9K. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. The ZED-F9K is the ultimate solution for autonomous robotic applications that require accurate positioning under challenging conditions.Īdditionally, this u-blox receiver supports I 2C (u-blox calls this Display Data Channel) which makes it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g.

The combination of GNSS and integrated 3D sensor measurements on the ZED-F9K provide accurate, real-time positioning rates of up to 30Hz.Ĭompared to other GPS modules, this breakout maximizes position accuracy in dense cities or covered areas. The module supports concurrent reception of four GNSS systems.

Note that the ZED-F9K can only operate as a rover, so you will need to connect to a base station. The ZED-F9K module is a 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2 meter accuracy! That's right, such accuracy can be achieved with an RTK navigation solution when used with a correction source. The ZED-F9K module provides a highly accurate and continuous position by fusing a 3D IMU sensor, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements.

The SparkFun ZED-F9K GNSS Breakout is a high precision, sensor fusion geospatial board with equally impressive configuration options and takes advantage of u-blox's Automotive Dead Reckoning (ADR) technology.
