Emlid RTK Corrections Service

Reliable Centimeter-Level Positioning Without Your Own Base Station

Achieve survey-grade GNSS accuracy by connecting your Emlid Reach receiver to Emlid Corrections service. Instead of deploying and maintaining a local base station, simply connect over the internet and receive real-time correction data from a network of continuously operating reference stations (CORS).

Whether you're surveying property boundaries, collecting GIS data, performing construction layout, or mapping with drones, Emlid's correction service helps you work faster with dependable centimeter-level positioning. 

How It Works

Skip the hassle of setting up a local base station. Emlid Corrections uses Virtual Reference Station (VRS) technology to provide real-time RTK corrections from a virtual base station at your location, giving you fast, dependable centimeter-level positioning anywhere within the supported coverage area.

This eliminates the need to set up your own base station for many applications while reducing equipment, setup time, and field complexity.

The service is activated directly in Emlid Flow — either by claiming the included free year with your Emlid Reach eligible receiver, or by entering a purchased license key.*

*Each license is tied to a single device and is non-transferable. The license is global — it covers all regions currently supported by the network, including any future expansions.

How does Emlid Corrections service work?

Professionally operated network of reference stations streams corrections directly to your device over the internet. The service uses a Virtual Reference Station (VRS) architecture—instead of relying on a single physical station kilometers away, a virtual base is generated right next to your location for faster convergence and consistent 1–2 cm (sub-inch) accuracy.

Does it work with my Reach receiver?

Emlid Corrections is fully compatible with Reach RS4 Pro, RS4, RX2, RS3, RX, and RS2/RS2+. All new models come with a free first year activated via the Emlid Flow app.

What are the benefits compared to CORS and other RTK service providers?

Most networks are single-baseline only — accuracy drops with distance and coverage is inconsistent. Emlid Corrections delivers uniform 2 cm VRS accuracy with professional infrastructure and support. Additionally, Emlid Corrections works straight out of the box with your Reach device.

Can I use my subscription on all my devices?

Each license is tied to one device serial number and cannot be transferred. If you need corrections for multiple receivers, each requires its own license.
