Cheapest overall in Texas

Tie: GEODNET RTK and RTKdata

$400 per 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, per year, both

These have the same lowest published yearly price among services that list Texas. Neither publishes enough local coverage detail to pick one for you, so check both maps for your site: GEODNET RTK · RTKdata.

Cheapest local network

AllTerra Central RTKNet

$2,000 per rover, per year

Regional network that lists Texas. Price is the operator's published list price.

Good to know: A local network is run by an operator that serves Texas, and you deal with that operator directly. Compare both coverage maps for your site. Nationwide coverage depends on 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 near your site.
