Worldwide Submeter and Centimeter Accuracy

Eos GNSS receivers are designed to be used with a variety of differential correction sources. Each source is available regionally, based on where your field work occurs. Eos can help you determine which Eos GNSS receiver model and accompanying differential correction source will give you the best value and accuracy. Below are the most commonly used differential correction sources supported by Eos GNSS receivers:

SBAS

Satellite Based Augmentation Systems (SBAS) are free, regional differential correction services that provide 30-60cm average accuracy with Eos GNSS receivers.
View SBAS Coverage Worldwide >

Galileo HAS

Galileo High-Accuracy Service (HAS) provides 10-20cm average accuracy with the Arrow Gold+ or Skadi Gold. Galileo HAS is a free differential correction service available globally.
Learn About Galileo HAS >

RTK Networks

Real-Time Kinematic (RTK) networks are free or paid, public or private sources of cm-level corrections. Our GNSS receivers support all existing RTK networks.

Atlas® Service

Atlas® service is a paid satellite subscription that provides 4-50cm accuracy worldwide.  It is recommended in places where SBAS, RTK networks and base stations are not available.

What Customers Are Saying

“The Skadi makes our work much easier because we can hold both the equipment and the iPad® in one hand. It’s become one of my favorite tools.”

Gus OteroGIS Specialist, Lee County Electric Cooperative / North Fort Meyers, Florida, United States

“We place a strong focus on serving our community and ensuring everything we do adds value for our members. With this improved workflow, we save time collecting GPS data, help our linemen return to their work faster, locate assets more easily during restoration or damage claims, and restore power more quickly. That’s true member value‑add.”

Leah MaldonadoSupervisor, System Graphics Team, Lee County Electric Cooperative / North Fort Meyers, Florida, United States

“We're using the Arrow 100+ with two tablets. The Arrow 100+ let us connect two devices to it at the same time and collect both the road centerlines and road striping at the same time as we're driving — instead of having to drive twice.”

John MurrellGIS Manager and 9-1-1 Coordinator, Waller County Road & Bridge Department / Waller County, Texas, United States
