Build Your Own Centimeter-Accurate RTK Network

If you’ve ever tried to build an autonomous rover, map a field, or track a drone, you know the frustration of standard GPS. Three to five meters of "accuracy" just doesn't cut it when you need precision. That’s where Real-Time Kinematic (RTK) positioning comes in.

Today, we're walking through an incredibly powerful, hybrid RTK hardware setup: using the tried-and-true ArduSimple simpleRTK2B stacked as a top hat on an Arduino Uno Q for our Base Station, while deploying the brand-new, all-band simpleRTK4 Basic Starter Kit as our Rover.

By tying them together with NTRIP (Networked Transport of RTCM via Internet Protocol), you can cast your own correction data across the internet and get reliable, sub-centimeter accuracy anywhere with cell service. Let’s dive into the hardware!
