New for Eos Newsletter May 2018: GNSS for beginners breaks down what you need to perform high-accuracy data collection. Your Atlas frequency firmware update is ready. Australian SBAS is approved for funding beyond 2019. Plus free guides, video and more!
High-accuracy data collection has come a long way since the USA launched the first GNSS constellation, GPS, in the 1970s. Today, all you need to get started with submeter or centimeter data collection is a smart device, a collection app, and a GNSS receiver that works with both.
Join Eos Positioning Systems at the 2018 Upper Midwest GEOCON in Wisconsin from May 23-24. Eos will be at the University of Wisconsin Student Center to answer questions about high-accuracy GNSS (GPS) data collection on mobile GIS workflows, with any device. Here's how to find Eos.
Elevation is the difference between the earth’s surface and a point above or below it. But the earth’s surface isn’t the same everywhere. It’s full of physical features, like mountains and valleys. So how can we measure elevation? Explore how in the latest Learning Center article from the Eos January 2018 issue.
What is the difference between the ellipsoid, mean sea level, geoid, geoid height, and orthometric height — and which one is right? Learn how the ellipsoid elevation your GPS receiver captures relates to the geoid, how to convert between the two so you can start using your data, and why most GPS receivers don't output the orthometric height you rely on.
UAVs and GNSS: Using High-Accuracy GNSS to Set Ground Control Points (GCPs) for UAVs Inexpensive unmanned aerial vehicles (UAVs) can collect a tremendous amount of valuable imagery that can be used to produce high-precision orthophotos resulting in 2 cm (or even less) pixel resolution. UAVs and GNSS receivers are amazing tools that complement each other.
In this hour-long webinar from Esri, Eos Positioning Systems, and SSVEC, you'll see how one electric co-op gathered 600 assets per day with centimeter accuracy. Through a combination of the ArcGIS platform, a new release of Collector for ArcGIS, and the Arrow Gold GPS / GNSS receiver, SSVEC overcame challenging, mountainous terrain to increase their asset data quality. Kurt Towler, Jeff Shaner, and their team walk you through the project workflow in this webinar.
From the Pioneers of High-Precision Bluetooth GNSS Receivers for iOS, Android and Windows Why Doesn’t My GPS Data Line up with My GIS? As GNSS receivers become more accurate, more affordable, and easier to use with your smartphone and tablet computer, they are going to challenge the accuracy of your GIS database. How many times
