About the Arrow 100 Submeter GPS Receiver

Real-Time Submeter GNSS Accuracy

The Arrow 100 submeter GPS receiver was designed specifically with GIS and mapping users in mind. This receiver squeezes more accuracy (submeter GNSS out of the box) from GNSS constellations and free SBAS corrections than any other receiver in the world. Thanks to its patented technology, you can use the Arrow 100 submeter GPS receiver under trees, around buildings, and in rugged terrain — where other receivers will fail to deliver. And thanks to real-time corrections processing in the field, you no longer have to spend time post-processing your data.

All Satellites & Signals

When having GPS satellites is just not enough, the Arrow 100 submeter GNSS receiver steps in to provide at least 24 more satellites from the remaining global constellations (i.e., GLONASS, Galileo, BeiDou). When its all-constellation support is combined with free SBAS corrections (in most regions of the world), the Arrow 100 can provide 60 cm real-time accuracy.

Supports Every Device and App

Thanks to Bluetooth® technology, the Arrow 100 submeter GNSS receiver is able to work with any mobile device, including iOS, Android, Windows, and Windows Mobile. It can also work with any third-party or in-house data-collection app. Simply browse our listing of field app partners or contact us for the app library to enable high-accuracy location within your own app.
