GPS-RTK2 Hookup Guide
Nate Introduction
The SparkFun GPS-RTK2 and GPS-RTK-SMA raise the bar for high-precision GPS. Utilizing the latest ZED-F9P module from u-blox the RTK2 and RTK-SMA is capable of 10mm 3 dimensional accuracy. Yes, you read that right, these boards can output your X, Y, and Z location that is roughly the width of your fingernail. With great power comes a few requirements: high precision GPS requires a clear view of the sky (sorry, no indoor location) and a stream of correction data from an RTCM source. We’ll get into this more in a later section but as long as you have two ZED-F9P breakout boards, or access to an online correction source, your ZED-F9P can output lat, long, and altitude with centimeter grade accuracy.
