How to use RTCM data to achieve RTK?

GPS/GNSS Development Boards

I’m using this example:

https://github.com/sparkfun/SparkFun_u- … Client.ino

on an ESP32 Thing Plus C with a ZED-F9P and it’s working fine, but it only outputs RTCM data. How do I apply the RTCM data to the GPS data and achieve RTK? My goal is to have the ESP32 Thing Plus C output RTK Latitude and Longitude to the serial monitor.

How do I apply RTCM data to the GPS data and achieve RTK?

Example output:

RTCM pushed to ZED: 245

RTCM pushed to ZED: 525

RTCM pushed to ZED: 3678

RTCM pushed to ZED: 3644

Any ideas would be appreciated! Thanks :smiley:

Hi Jacob,

It sounds like everything is working OK. But, correct, there is nothing in that example to actually print out the position.

Please try Example17. It is better-structured and uses callbacks to: display your position; and push NMEA GGA data to the server. Some NTRIP servers require the GGA data, others don’t. If the GGA data causes problems, you can comment this line to disable the push:

Have fun!
