Atlas® Service

When no RTK network or base station is available, the Arrow Gold® can be used with Atlas® subscription service worldwide. Available subscriptions are H10 (4cm), H30 (15cm) and Basic H50 (30cm).

Learn about Atlas® >


If no RTK, base station, or Atlas® service is being used, the Arrow Gold® will work with regionally available free SBAS corrections when available. Using SBAS, this will provide ~30 cm horizontal accuracy.

SafeRTK - How to stay productive when RTK coverage is inconsistent GPS GIS GNSS remote mobile mapping

What is SafeRTK®?

There is nothing more frustrating than losing RTK network connection while working in areas with spotty cell coverage. SafeRTK® is the answer. SafeRTK® is a proprietary feature included exclusively with the Arrow Gold® and Arrow Gold+™ receivers. When cellular connection to your RTK network drops, SafeRTK® takes over within a few seconds and allows you to maintain RTK-level accuracy for up to 20 minutes (unlimited with Atlas® H10 subscription). So you can stay productive, until the Arrow Gold® automatically reconnects to the RTK network as coverage returns. This enables uninterrupted RTK accuracy in spotty areas.

Want Even More Features? Consider the New Arrow Gold+™

Customers considering the Arrow Gold® GNSS receiver can now choose between the standard Arrow Gold® and the more advanced Arrow Gold+™ model. The Arrow Gold+™ includes all the same features of the standard Arrow Gold® GNSS receiver. However the plus model, with its 800+ channels, also includes support for additional GNSS signals, India’s IRNSS (L5), longer battery life, built-in functionality of the Eos Bridge™ Bluetooth® connector, and the ability to connect multiple mobile devices to one receiver. This is the most future proof, ubiquitous, and productive GNSS receiver Eos offers.

Please note: Existing Arrow Gold® GNSS receivers cannot be upgraded to the new Arrow Gold+™ model.

Arrow Gold Plus GNSS GIS GPS Eos Receiver

Even More Signals Supported

The Arrow Gold+™ supports even more signals, resulting in faster RTK convergence and better RTK performance in tough conditions. Additional signal support includes: the concurrent use of the BeiDou B3 and GPS L5 signals and more GLONASS, BeiDou, QZSS and IRNSS signals. The Arrow Gold+™ also supports the upcoming Galileo E6 HAS, which will broadcast differential corrections for GPS and Galileo satellites.

Longer Battery Life

The Arrow Gold+™ offers 11 hours of battery autonomy (increased from 7.5 hours).


The Arrow Gold+™ has the functionality of the Eos Bridge™ Bluetooth® connector built in. Connect your Arrow Gold+™ to any third-party sensor (e.g., laser rangefinder), and the Arrow Gold+™ will stream the content of that sensor to your iOS or other mobile device via its datastream.

Connect Multiple Mobile Devices

The new multipoint feature allows you to connect more than one device to a single Arrow Gold+™ receiver.
