Feature Story
Mapping The Western Hemisphere’s Deepest Cave with High Accuracy
The Proyecto Espeleológico Sistema Huautla (PESH) team is pushing the boundaries of cave exploration by mapping Mexico’s Sistema Huautla, the Western Hemisphere’s deepest cave system, with unprecedented accuracy. With help from an Arrow 100 GNSS receiver, they can determine cave coordinates to submeter accuracy, significantly enhancing the precision of their maps. This allows researchers to rectify errors in past surveys, reconnect lost cave entrances, and more accurately locate paleontological finds and unique cave species. The project’s ultimate objective is to expand Sistema Huautla’s mapped length and depth, potentially identifying it as the world’s deepest cave.

Galileo High Accuracy service undergoes successful testing in Africa
By European Union Agency for the Space Programme
The Galileo High Accuracy Service (HAS) recently achieved a successful demonstration in Dakar, Senegal. Collaborating with local geomatics professionals, the SatNav Africa Joint Programme Office highlighted Galileo HAS’s ability to deliver real-time, sub-decimeter accuracy via Precise Point Positioning (PPP). Using the Arrow Gold+ GNSS receiver, the Dakar trial team validated ground control points (GCPs) with accuracy within 18 cm after a brief convergence period. This advancement offers significant improvements for high-precision applications across Africa and beyond.
Eos was pleased to receive the Infrastructure award at Esri’s 2024 IMGIS Conference in Palm Springs. Known for its high-accuracy GNSS receivers for GIS applications, Eos showcased innovations like the Skadi Series™ GNSS receivers with tilt compensation and the Skadi Smart Handle™, which allows for easy RTK mapping through ArcGIS mobile apps. Esri recognized Eos’s advancements in leveraging ArcGIS for effective infrastructure management.
Dr. Kyle Emery, an Assistant Researcher at UC Santa Barbara’s Marine Science Institute, is leading a project to monitor seasonal and event-driven changes in California’s beaches and dunes. His team collects data across 14 coastal sites using technologies like the Arrow Gold+ GNSS receiver, ArcGIS Field Maps, and a DJI Mavic 3 Multispectral drone. Emery aims for his research to benefit local coastal communities and offer a replicable method for researchers worldwide to track beach ecology over time.

Uncovering the legacy of Indigenous residential schools through GIS
By Rosalyn Laiken, Esri Canada
Following the discovery of over 200 possible graves at the Kamloops Indian Residential School, Dr. Sarah Beaulieu identifies unmarked burial sites at former residential schools in Canada. Dr. Beaulieu’s work employs ground-penetrating radar, GNSS, and ArcGIS Field Maps to map these sites — while collaborating with Indigenous communities. Her goal is to address the legacy of residential schools and support truth and reconciliation. This initiative empowers Indigenous voices, facilitates healing, and fosters awareness of historical truths while respecting community privacy.

Configuring Mock Location on Android With Your Arrow GNSS Receiver
In order for location-aware Android apps to have access to the more accurate position of your Eos GNSS receiver, Mock Location must first be enabled. In this article, we guide you through enabling Mock Location on your Android device.
How to Configure Eos Tools Pro for RTK on Android
To acquire RTK corrections with your Eos GNSS receiver, you need an app capable of receiving and transmitting RTK corrections. Eos Tools Pro was built to handle this task. In this article, we show you how to connect your Eos receiver to, and configure, Eos Tools Pro (ETP) on Android.
