Your question is very poor framed, what documentation have you reviewed so far? What does your set up involve?
You have a unit configured as a Base to generate them. The Base antenna should ideally be rigidly mounted, and surveyed accurately.
Or you use a local/regional NTRIP server or RTK Network service.
This is exactly what i’m asking for. If i setup a unit as a base i don’t need an rtk network or NTRIp cause there’s no one near me. And Also can u tell me how whart exactly i need for a base to set it up?
