SparkFun GNSS-RTK L1/L5 Breakout - NEO-F9P (Qwiic)

The SparkFun GNSS-RTK L1/L5 Breakout - NEO-F9P (Qwiic) is a high-precision GNSS board with equally impressive configuration options. The NEO-F9P utilizes the L1/L5 bands instead of the the more commonly seen L1/L2 option. Utilizing the L5 band, the NEO-F9P delivers improved performance under challenging urban environments because the L5 signals fall within the protected ARNS (aeronautical radio navigation service) frequency band. This band is less subject to RF interference.

The NEO-F9P module is a powerful 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with 10mm, three-dimensional accuracy! That's right; such accuracy can be achieved with an RTK navigation solution when used with a correction source. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail! The module supports the concurrent reception of four GNSS systems. This module features a survey-in mode, allowing the module to become a base station and produce RTCM 3.x correction data.
