Learn how to read the RTK coverage map, understand 2 cm and 2-10 cm accuracy zones, and verify your area before deployment. 20,000+ stations, 140+ countries.
Check coverage in your area before heading to the field: Open Live Coverage Map
RTKdata.com operates 20,000+ active reference stations worldwide across 140+ countries and 4,600+ cities, delivering centimeter-level positioning accuracy.
The coverage map shows two zones:
2 cm zone — RTK FIX reliable, survey-grade accuracy
2–10 cm zone — RTK FIX achievable, good for mapping and agriculture
If your work area is inside a colored zone, RTKdata will work for you. If you're outside or near the edge, start a free trial and test on-site — some areas have coverage beyond what the map shows.
Check the map — verify your project area has coverage: rtkdata.com/coverage
Test on-site — run a quick outdoor FIX test before committing to a full survey day
Note on heights — elevation values are ellipsoidal by default. Apply a geoid model if you need orthometric (sea level) heights. See Understanding Heights.
Use the AUTO mountpoint — it automatically applies the correct regional datum:
United States
NAD83(2011)
Europe
ETRS89 / ETRF2000
Australia
GDA2020
New Zealand
NZGD2000
For global applications, use AUTO_WGS84 or AUTO_ITRF2020. See Network & Mountpoints for details.
Try it anyway — the free trial lets you test. Coverage may extend beyond the map.
Host a base station — RTKdata provides free hardware in exchange for 1 year of free service. See Host a Base Station.
Check back regularly — the network is constantly expanding with new stations.
Start your 30-day Free Trial — no credit card required, auto-ends.
