How to Set Up High-Precision GNSS on a Raspberry Pi: Part 2
Chris and Lauren are back with their Raspberry Pi and GNSS Flex boards to show you how to set up RTK on the project we built in the last video guide!
If you’ve been following our Friday Product Post series, you know that high-precision positioning is within reach for your Raspberry Pi projects use the SparkFun and SparkPNT GNSS Flex ecosystem. In our latest video, "Achieving High Precision RTK GNSS on a Raspberry Pi," we take things a step further by moving from a stationary setup to a fully mobile, centimeter-level accurate system!
The GNSS Flex system is designed to be modular with a standardized pin layout that keeps the ecosystem pin-compatible for upgrades and allows boards to be easily swapped for repairs. The ecosystem is comprised of two boards, which mate through two 2x10-pin, 2mm pitch headers. The SparkPNT GNSS Flex modules function as plug-in boards that feature different GNSS receivers. They are designed to mate with GNSS Flex carrier boards for various purposes; such as a breakout board, Raspberry Pi pHAT, SparkPNT product line, etc.
This video serves as the second part of our deep dive into GNSS on the Pi. So, if you haven’t watched Part 1 yet, we highly recommend starting there. In the first installment, we covered the hardware assembly, OS configuration, and basic connection of a Raspberry Pi to the GNSS Flex system.
Once you have your hardware talking, this second part, RTK GNSS on a Raspberry Pi, is all about precision and mobility. We ditch the wall tether for a portable battery, swap the monitor for a touch display, and hook up a vehicle-rated antenna to hit the road.
Whether you are building an autonomous rover or surveying/mapping and area, standard GPS accuracy often isn't enough. By implementing RTK (Real-Time Kinematics), you can achieve accuracy down to the centimeter, making your data significantly more valuable and actionable!
