Product description: GNSS Timing Breakout - ZED-F9T - Qwiic - SparkFun GPS-18774
GNSS Timing Breakout is a module equipped with the ZED-F9T multiband receiver from u-blox. It receives data from the major positioning systems which include GPS, GLONASS, Galileo and BeiDou. It supports L1 / L2 / E5b bands, provides timing accuracy of up to five nanoseconds under clear skies without external GNSS correction, making it ideal for applications where high timing accuracy is required. The GNSS Timing Breakout also features a Qwiic connector with an I2C interface, in addition, UART and SPI interfaces are available on the leads, as well as a USB connector and a battery connector.
Detailed user guide and useful documentation and schematics are available on manufacturer's website - check it out!

Satellite navigation - what is GNSS?
GNSS is a Global Navigation Satellite Systems, which covers the whole Earth. Its main function is to determine your position. GNSS systems also include GPS Global Positioning System and GLONASS. Wondering how satellite navigation works? It's simple - as a type of radio navigation, it uses radio waves that are broadcast from artificial satellites to determine the position of points and moving receivers along with the parameters of their movement on the Earth's surface.
