Get unmatched RTK coverage, accuracy, and reliability

An actively monitored and remotely managed network of thousands of base stations contributes to 99.9% network uptime.

Virtual RTK

For high-precision with country-wide coverage.
~10 cm horizontal and vertical accuracyAccuracy and fix times are measured on a survey grade antenna and dual frequency receiver in open sky environments. Environmental conditions, baseline distance, and equipment capabilities will influence your achieved accuracy.
Peak accuracy in 30 seconds Accuracy and fix times are measured on a survey grade antenna and dual frequency receiver in open sky environments. Environmental conditions, baseline distance, and equipment capabilities will influence your achieved accuracy.
Available in the contiguous US, UK, and EU
Powered by advanced SSR technology Point One uses advanced SSR (State Space Representation) modeling to estimate the optimal corrections for large coverage areas. The output of this model is converted back to standard RTK messages so the service is compatible with almost any RTK capable receiver.
Great for automotive applications and GIS where consistent coverage is most important

True RTK

For the most precision-critical applications.
1-3 cm horizontal and vertical accuracy Accuracy and fix times are measured on a survey grade antenna and dual frequency receiver in open sky environments. Environmental conditions, baseline distance, and equipment capabilities will influence your achieved accuracy.
Immediate fix time Accuracy and fix times are measured on a survey grade antenna and dual frequency receiver in open sky environments. Environmental conditions, baseline distance, and equipment capabilities will influence your achieved accuracy.
Available across the US, UK, EU, KOR, AUS, NZ, and JP
Gold standard single-base corrections Single baseline RTK provides unrivaled accuracy in 3D and a stable reference point for survey and GIS work.
Great for survey, damage prevention, drone inspection and delivery, construction, and mapping
