When your research leaves the lab and enters the field, accuracy becomes the foundation of every insight. Whether you’re studying ecosystems, coastlines, caves, bathymetry, erosion, or something else, precise location data ensures your measurements are meaningful, repeatable, and defensible. Our GNSS receivers give researchers like you the confidence to collect geospatial data anywhere — from remote islands to urban watersheds — without sacrificing accuracy or flexibility. Eos GNSS receivers integrate seamlessly with the tools you already use, from mobile apps to sensors and drones, so your workflow stays focused on science, not hardware limitations. Built for rugged environments and adaptable to diverse methodologies, they help you associate high-accuracy positions with any dataset — even in challenging conditions. The result? Reliable data that supports long-term monitoring, validates models, and turns field observations into actionable knowledge. Wherever your curiosity takes you, our GNSS solutions keep your research grounded in precision.
High Accuracy, Anywhere
Wherever your field work takes you, our GNSS receivers have a solution to provide high accuracy. Moreover, our teams will help you identify the most cost-efficient solution for your project’s needs.
Training-Friendly Hardware
Multi‑device Bluetooth® connections and familiar mobile apps make student and volunteer training fast, whether you’re mapping invasive species on Catalina Island or running a beach‑survey crew.
App Agnostic, BYOD Friendly
Our receivers work with any iOS®, Android™, or Windows® device and any field app (including ArcGIS Field Maps, Survey123, custom apps, and partner tools), so your workflow meets the study — not the other way around.
Built for the Field
From surf zones to glaciers to jungles, researchers report reliable, repeatable results — validating cave surveys, guiding restoration plots, and building long-term ecological baselines.
GNSS that Keeps Up with Curious Minds
If your study site refuses to sit still, your positioning shouldn’t either. Eos GNSS receivers have a habit of tagging along with curiosity — flying under drones to stitch crisp orthos, riding USVs through volcanic calderas, and threading canyon trails where GPS alone falls short. They help you chase kelp‑forest sand subsidies across seasons, prove whether a beaver‑dam analog actually slows incision, and turn “interesting EM spike” into “verified groundwater sample.” They’ll find a cave entrance hidden by rainforest and still play nice with your go‑to apps, your field tablet, and that specialty sensor you swore would never talk to anything. And when there’s no cell coverage and no base station in sight, Galileo HAS has your back — because the pursuit of evidence shouldn’t stop at the edge of the map.
