Product description: GNSS-RTK L1/L5 Breakout Module - NEO-F9P - Qwiic - SparkFun GPS-23288
The SparkFun GNSS-RTK L1/L5 Breakout is a GNSS board that uses both L1 and L5 bands, significantly improving performance in challenging urban environments. With a 184-channel u-blox NEO-F9P receiver, the module can receive signals from four GNSS constellations, providing an incredible 10 mm accuracy when using RTK correction. The module also supports a "survey-in" function, allowing it to be used as a base station to generate RTCM 3.x correction data. The board has five simultaneously active communication ports: USB Type-C , 2x UART, I2C and SPI , making it flexible and easy to integrate with other systems. The module supports multiple protocols, including NMEA and UBX, and offers the possibility of configuration using the popular u-center software or the Arduino library.

What is GNSS?
GNSS, or Global Navigation Satellite Systems, is a global satellite navigation system that covers the entire Earth. The main purpose of GNSS is to determine the user's position. GNSS systems include GPS (Global Positioning System) and GLONASS. Are you wondering how satellite navigation works? It is a form of radio navigation that uses radio waves emitted by artificial satellites to precisely determine the location of points and mobile receivers on the Earth's surface, as well as the parameters of their movement.
Module Applications
The module finds wide application in various fields, such as:
- Robotics: precise positioning of autonomous vehicles.
- Surveying: creating maps and modeling terrain with high accuracy.
- Drones: flight stabilization and accurate location tracking.
- Internet of Things (IoT): real-time location monitoring in smart city applications.
The module supports simultaneous reception of four GNSS systems.
