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.
Learn about RTK >
Base Station
Base stations are reference stations that broadcast centimeter-level differential corrections to an approximate 50 km (31 mi) radius. Certain Arrow receivers can be installed and operated as a private base station.
Learn about the Arrow Gold+ >
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
“There aren’t any RTK networks in Antarctica. That sent us looking for the Arrow Gold+ and Galileo HAS corrections. When we found these, we realized we had a possible solution.”
Kevin WilcoxResearch Scientist, Ocean Mapping Group / Fredericton, New Brunswick, Canada
“With the accurate locations from the Arrow Gold, it’s like having a cheat code.”
Jack BraunschweigerCity Planning Manager, Do LaB / Los Angeles, California, United States
“At EMWD, safety is always our top priority. With this technology, our crews can capture asset data from a safe distance, such as using a laser instead of working close to a trench. The smart handle allows our technicians to map valves in intersections without initiating traffic control, keeping both our team and the public safe while maintaining efficiency.”
Andrea Regalado Enterprise GIS Manager, Eastern Municipal Water District (EMWD) / Perris, California, United States
Designed to Work With Partner Software and Hardware
Eos Positioning Systems partners with a variety of software and hardware providers. This ensures your Arrow or Skadi GNSS receiver seamlessly integrates with the world’s leading mobile mapping technologies. Additionally, our receivers are able to work with any third-party app, even if it is not listed on our website.

Explore Eos Solutions
Eos offers a number of mobile mapping solutions designed for GIS users. Learn more about each:
Skadi Tilt Compensation™
Skadi Tilt Compensation is the first tilt compensation solution specifically for the GIS market. With this solution activated, field workers can rectify errors introduced from tilted angles during data collection with a survey range pole. This extremely accurate feature introduces only about 0.3 millimeters (0.01 inches) of inaccuracy per degree of tilt. It is recommended for crews who use range poles, require centimeter-level (RTK) accuracy, and want to eliminate time spent leveling their poles on each point. Skadi Tilt Compensation is available as an optional upgrade for the Skadi 200, Skadi 300, and Skadi Gold.
Eos Laser Mapping™ for ArcGIS
Eos is excited to bring you the world’s first laser mapping solution for Esri’s ArcGIS apps. The Eos Laser Mapping solution is for field crews that need to map hard-to-occupy assets with 3D, survey-grade accuracy — without having to physically stand on top of every single point. This is great when the assets you need to collect are located in environments that are either GNSS-impaired (with poor line-of-sight to positioning satellites), or in areas that are difficult and dangerous to reach. Eos Laser Mapping is currently available for iPad and iPhone as a free solution, in conjunction with our partnerships between Esri and Laser Technology (LTI).
Eos Locate™ for ArcGIS®
Bring your buried assets to life! Accurately mapping buried legacy pipe has traditionally required digging spot holes, physically exposing the buried pipe, and then capturing its location. This is time consuming, expensive, and inconvenient for everyone who lives and works in the area. Are you ready to bring your buried assets to life without digging? Eos Locate for ArcGIS is the world’s first real-time, survey-grade underground mapping solution for ArcGIS. With Eos Locate , it takes just a few seconds to locate and map buried infrastructure with highly accurate coordinates and depth below cover, directly into ArcGIS. This solution drastically cuts down time and labor spent in the field remapping existing utilities, while improving the accuracy of geospatial records.
