GPS modules contain tiny processors and antennas that directly receive data sent by satellites through dedicated RF frequencies. From there, it’ll receive timestamp from each visible satellites, along with other pieces of data
The SparkFun NEO-M9N GPS Breakout is a high quality GPS board with equally impressive configuration options. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS.
This maximizes position accuracy in challenging conditions, increasing precision and decreases lock time; and thanks to the onboard rechargeable battery, you’ll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don’t have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.
- 25Hz Max Update Rate (4 concurrent GNSS)
- Supports NMEA, UBX, and RTCM protocols over UART or I2C interfaces
- Software Configurable Geofencing, Odometer, Spoofing Detection,External Interrupt
- Integrated U.FL connector for use with antenna of your choice
- Tracking GPS+GLONASS
