- Needs cell signal?
- Yes: NTRIPThe standard way RTK corrections are sent over the internet. Think of it as internet radio for correction data.Full definition needs internet at the RoverThe receiver that moves around the job, like a survey pole or a drone. It uses the base's corrections to find its exact spot.Full definition (cell data or a phone hotspot). General rule, not an operator statement.
- Network
- Own-built Base stationA GNSS receiver sitting still on a known spot. It figures out how wrong the satellite signals are right now and shares that as corrections.Full definition at 30-40 km spacing (operator claim)

- Satellites (ConstellationOne family of navigation satellites, like GPS, GLONASS, Galileo or BeiDou. More constellations means more satellites to use.Full definition)
- GPSThe US satellite navigation system. People often use "GPS" to mean all satellite positioning.Full definition, GLONASS, Galileo, BeiDou, QZSS
- Datum / EpochOne moment of GPS measurement. A receiver logging at 1 Hz records one epoch every second.Full definition / GeoidA lumpy, imaginary "sea level" surface around the whole Earth. Elevations are measured from it.Full definition
- ITRF2014, NAD83, ETRS89 (others for non-US regions)
- Must send GGAA short message your rover sends with its rough location. VRS and nearest-station streams need it to know where you are.Full definition position?
- Yes for VRSVirtual reference station. The network blends nearby stations to create a pretend base right next to you, which keeps the baseline short.Full definition / network / nearest-base mountpoints (your rover must send its position as an NMEAA common text format GPS receivers use to report position and status. GGA is one NMEA message.Full definition GGA message). General rule based on the mount types.
