Unable to Include Correction Data with SparkFun ZED-F9R PHAT

Selling point taken from https://www.sparkfun.com/products/16475:

“… with ~0.2 meter accuracy! That’s right, such accuracy can be achieved with an RTK navigation solution when used with a correction source”

There isn’t a method for adding a correction source to the ZED-F9R PHAT. The examples only show a user how to get latitude and longitude or time, but there are no examples including correction data. Further, the various documentation do not mention a client or method to update the GNSS data with differential correction from reference stations. I have a valid account with FDOT’s Florida Permanent Reference Network which works with other clients, but there is no client or code included to allow the SparkFun board to get updated correction data.

Does anyone have any examples showing differential correction from a known good caster over IP on a Raspberry Pi?

I’m trying to do this too! I think you have to use RTKLib to receive the ntrip correction from the internet or a correction from local base via radio, wifi or bluetooth.

Eventually you have to configure RTKlib to interpret your signal and convert it to RTCM 2 or 3.

I hope this helps you and if you have a different solution share it!

I’ve got this to work on an Jetson nano and a RaspberryPi.
