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.

The RP2040 mikroBUS™ Development Board is our latest RP2040 microcontroller (MCU) ‎development board.

The SparkFun GPS ZED-F9R is the next iteration of u-blox's GPS offerings!

This board supports concurrent reception of 4 GNSS constellations for position accuracy in challenging conditions increasing precision and decreasing lock time.
