Needs cell signal?

Yes: NTRIPNTRIPThe standard way RTK corrections are sent over the internet. Think of it as internet radio for correction data.Full definition needs internet at the roverRoverThe 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.

Confirmed live: a public sourcetable request to 165.239.144.7:2101, 168.179.231.11:2102 answered on Oct 17, 2026 with 42 mountpoints.

Correction formats

RTCM 3RTCMThe common format RTK corrections are written in, so different brands can understand each other.Full definition.1, RTCM 3.2, CMR+CMRxTrimble's own compact correction format. Some networks offer it for Trimble gear and machine control.Full definition, CMRx

Satellites (constellationsConstellationOne family of navigation satellites, like GPS, GLONASS, Galileo or BeiDou. More constellations means more satellites to use.Full definition)

GPS, GLONASS, Galileo, BeiDou (GNSS-VRS RTCM32 mount)

Datum / epochEpochOne moment of GPS measurement. A receiver logging at 1 Hz records one epoch every second.Full definition / geoidGeoidA lumpy, imaginary "sea level" surface around the whole Earth. Elevations are measured from it.Full definition

NAD83(2011)NAD 83(2011)The official US datum for horizontal position right now. Most state networks give coordinates in it.Full definition epoch 2010.00; legacy NAD83/94 (HARN) casterCasterThe internet server that hands out correction streams. Your rover logs in to it, like tuning into a radio station.Full definition

Must send GGAGGAA 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 VRSVRSVirtual 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 NMEANMEAA 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.
