TrueRTK Live Network Coverage
Frequently Asked Questions
RTK (Real-Time Kinematics) is a positioning method where a fixed base station sends real-time corrections to a GNSS rover. This removes common signal errors and improves accuracy from meters to centimeters.
Please note: Performance depends on the accuracy of the base location, the quality of the sky view, and distance to the rover.
RTK provides centimeter-level accuracy. This precision is essential where even minor errors can have major consequences. CPC’s TrueRTK corrections offers fast fix times and consistent accuracy, even in challenging environments.
An RTK base station is a fixed GNSS receiver with a known position.
It continuously monitors satellite signals and sends correction data to rovers in real time. CPC’s network includes over 1,400+ stations globally, eliminating the need for you to set up your own base.
RTK is widely used in surveying, construction layout, mapping utilities, agriculture and robotics.
There are three main types:
- RTK: Real-time, base-to-rover corrections with centimeter-level accuracy.
- PPP: No base required; slower convergence.
- SSR: Models GNSS errors; requires specialized receivers.
Precision GNSS uses correction data to reduce positioning errors caused by satellite orbit, clock drift, and atmospheric delays.
RTK systems use carrier-phase measurements, which are far more precise than standard code-based GNSS. However, they come with ambiguity that must be resolved using advanced math. CPC TrueRTK handles all this complexity behind the scenes, giving you fast, accurate positions without needing to manage the process manually.
Both deliver RTK corrections. NTRIP is the industry standard, supported by many devices. TrueRTK, in addition, adds authentication and encryption for better reliability and data security.
CPC TrueRTK offers several advantages over standard GNSS:
- Centimeter-Level Accuracy: Achieve 1–3 cm precision compared to the 1–10 meter drift of standard GNSS.
- No base station required: Access reliable corrections without the cost and setup of a personal base.
- Quick Deployment: Connect and start working in minutes—no complex setup or configuration needed.
- Live Coverage Map: Easily check available service in your area using our public reference station map.
- Broad Compatibility: Works seamlessly with any dual-band GNSS receiver or NTRIP client.
