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.
Here, we outline the key differences between our ZED-F9P and ZED-X20P breakout boards so you know exactly how to upgrade your projects to the newest technology.
This tutorial will walk you through setting up a base and rover so that your rover can have the ~14mm accuracy that surveyors use! This can be useful for all sorts of projects including agriculture, drones, mapping, and even some extreme geocaching.
This tutorial will go over how to use an ESP32 microcontroller to connect to u-blox Thingstream and PointPerfect over Internet to push correction data to a high precision GNSS.
The SparkFun GNSS Correction Data Receiver - NEO-D9S is a satellite data receiver for L-band correction broadcast. It can be configured for use with a variety of correction services including u-blox's PointPerfect satellite GNSS augmentation service.
This board supports concurrent reception of 4 GNSS constellations for position accuracy in challenging conditions increasing precision and decreasing lock time.
