Connecting the GPS-RTK to a Correction Source
To get the most out of the ZED-F9K you will need an RTCM correction source. There are a few methods of adding a RTCM correction source. If you have been following along with our GPS-RTK and GPS-RTK2, you can pipe correction data from a wireless network, LoRa, or cellular network. Depending on your setup, you will probably need a ZED-F9P for a correction source. For more information, check out these tutorials.
