ESP32 based Local RTK Network

This video tutorial provides a guide on using the ESP32 XBee NTRIP Master to send RTCM correction data, NMEA sentences, and other commands over a local Wi-Fi network to and from GNSS modules. This differs from previous videos, where correction data was sent via a cloud-based NTRIP caster like RTK2Go or to a DePin service like ONOCOR for crypto mining. This tutorial includes step-by-step instructions for configuring the ESP32 XBee’s TCP/UDP socket and NTRIP caster functions to transmit data within a local network, eliminating the need for internet-based NTRIP servers. This tutorial uses the UNICORE UM890 modules to demonstrate the workflow, but any other GNSS module will work similarly.
