UHF radio vs internet corrections for RTK
The communication method changes field logistics, but it does not replace measurement quality control.

RTCM messages: checking correction compatibility
A shared RTCM label is a starting point, not a complete compatibility test.

NTRIP explained: caster, client and mountpoint
NTRIP carries GNSS data over the internet; the stream content determines how the receiver can use it.

CORS and network RTK: understanding the reference service
Continuously operating stations provide reference observations; network services process or distribute them in different ways.

What SBAS adds to satellite positioning
Satellite-based augmentation provides correction and integrity information, but it is different from a local RTK workflow.

RTK vs PPK: choosing when to process corrections
RTK provides results during collection. PPK computes positions afterward from recorded observations.
