About the Arrow Lite Submeter GPS

Submeter GPS (60 cm) Real-Time with Free SBAS

The Arrow Lite Submeter GPS receiver was designed for the North American GIS and mapping communities. Arrow Lite Submeter GPS squeezes more accuracy from the GPS constellation and free WAAS corrections than any other receiver on the market. Thanks to patented technology, the Arrow Lite submeter GPS receiver works under trees, around buildings, and in rugged terrain. It even works where other receivers fail to deliver. Like all Arrow Series™ receivers, the Arrow Lite provides real-time submeter GPS corrections in the field. So there’s no more post-processing. Get higher accuracy and greater productivity from the unmatched value of Arrow Lite. Please note the Arrow Lite works only with GPS satellites, whereas Arrow 100 works with all 4 GNSS constellations; this is a popular consideration among our Arrow customers.

Get Higher Accuracy from Free SBAS to Achieve Submeter GPS Location

The Arrow Lite submeter GPS receiver takes advantage of free GPS positioning and SBAS corrections to deliver unprecedented, real-time, 6o cm (submeter GPS) positioning to your field crews, no matter what smartphone or tablet they are using. Access the highest degree of accuracy possible from the available GPS and SBAS satellites, at the lowest possible price point. The Arrow Light submeter GPS is designed to get more out of the available free satellites. So you can have high-accuracy on any budget, confidently, reliably, and easily.

How does Arrow Lite extract submeter data with just GPS and SBAS?

Where other receivers may fail, the Arrow Lite submeter GPS receiver steps in to support more GNSS and SBAS connections. Then, through patented technology, the Arrow Lite is able to extract a higher degree of accuracy than most other receivers. With Eos Tools Pro, you can monitor your location metadata to see just how accurate your coordinates are. Submeter GPS locations have never been easier.

Submeter GPS for Any Device or App

Do your teams need to work on existing Windows notebooks, a company iPad, or their own Android devices? With the Arrow Lite submeter GPS receiver, they can work on any or all of the above. Thanks to Bluetooth^®  connectivity, the Arrow Lite can connect to any smart device. And with a variety of Eos partners providing field apps we recommend — as well as a metadata library to seamlessly integrate your own app — the Arrow Lite can work with any software, too. As more and more apps and devices are introduced into the market, this makes the Arrow Lite and all Arrow Series™ receivers one of the smartest choices for building a future-proof, submeter GPS solution.
