I want to know how RTK works with the K803 and whether I need to set up my own base station.
RTK works like this: your rover receives correction data from a base station or CORS network to achieve centimeter-level accuracy. And you will need a GNSS receiver as a base station to send corrections to the rover.
Got it. So how do I actually set up my own base station for the K803? And how do I know if it's working?
