Well that was fast! We plan to have more GPS-RTK boards available at the beginning of October. Thanks to GPS you can quickly know where you are anywhere on the globe within 30 seconds.

Thanks to GPS you can quickly know where you are anywhere on the globe within 30 seconds. Pretty impressive! But what if you need better accuracy than the 2.5 meters accuracy that GPS provides? GPS Real Time Kinematics (RTK) has 25mm accuracy. You can now know where you are (or any object) within one inch.
The SparkFun GPS-RTK board is a powerful breakout board for the the NEO-M8P-2 module from Ublox. The NEO-M8P-2 module is the top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK. The NEO-M8P-2 is unique in that it is capable of both rover and base station operations. The ‘-2’ designation means this module has survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data.
The GPS-RTK has four communications ports:
The USB and UART ports are common and well documented. We’ve also written an Arduino library for Ublox modules to make reading and controlling the GPS-RTK over Qwiic a breeze.
We’ve even included a rechargable backup battery to keep the latest module configuration and satellite data available for up to two weeks. This battery helps ‘warm-start’ the module decreasing the time-to-first-fix dramatically.
We’ve written multiple tutorials to get you started:
The number of configuration options of the NEO-M8P-2 is incredible! Geofencing, variable I2C address, variable update rates, even the high precision RTK solution can be increased to 4Hz. This is a powerful module.
What can we do on the next rev of this product to make it better? (a one question google form)
