Worldwide Submeter and Centimeter Accuracy

Arrow Series®  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 Arrow 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 Arrow Series®  GNSS receivers:


Satellite Based Augmentation Systems (SBAS) provide 30-60cm average accuracy. SBAS are free, regional sources of submeter differential corrections that are typically owned and operated by governing bodies.

RTK Networks

Real-Time Kinematic (RTK) networks are free or paid sources of centimeter-level differential corrections. They are owned and operated by public and private organizations regionally. All existing RTK networks can be used with Arrow GNSS receivers.

Base Station

Base stations are reference stations that broadcast centimeter-level differential corrections to an approximate 50 km (31 mi) radius. The Arrow Gold® can be installed and operated as a private base station.

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.

Eos Locate for ArcGIS Esri Collector Field Maps Eos Tools Pro underground utility mapping GIS GNSS

Eos Locate™ for ArcGIS®

Bring your buried assets to life! Accurately mapping buried legacy pipe has traditionally required dig 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.

Eos Laser Mapping: Laser offsets and sideshots for Esri ArcGIS with Laser Tech LTI laser rangefinders and Eos Arrow GNSS receivers GPS mapping, total station like workflow

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).
