Affordable Survey-Grade GNSS Receiver offering RTK Precision
The Arrow Gold+™ is the first high-accuracy Bluetooth® GNSS receiver on the market to implement all four global GNSS constellations (GPS, GLONASS, Galileo, BeiDou), all available frequencies, and satellite-based RTK augmentation on any iOS®, Android™, and Windows® devices. Moreover, this GNSS receiver has full-band support for all GNSS signals including Galileo High-Accuracy Service (HAS). Both the Arrow Gold+™ and its predecessor model, the Arrow Gold®, work with all off-the-shelf mobile apps.
Accurate, Productive, Flexible
Survey-Grade GNSS Receiver
The Arrow Gold+ GNSS receiver provides survey-grade accuracy from a variety of differential correction sources, including RTK networks and base stations, Galileo HAS, and Atlas® satellite service.
Productive Positioning
The Arrow Gold+ is our most efficient GNSS receiver, supporting all global and regional GNSS constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS (excluding S-Band)), all available GNSS frequencies and 800+ channels for maximum field productivity.
Completely Flexible
Both the Arrow Gold+ and Arrow Gold are agnostic, hence compatible with all consumer mobile devices and any third-party data collection apps.

What Accuracy and Flexibility look like with the Arrow Gold®
- 1 cm accuracy with RTK
- 10-15 cm accuracy with Galileo HAS
- 4 cm accuracy worldwide w/ Atlas® subscription
- Retain RTK in poor cell areas with SafeRTK®
- Access all GNSS constellations and signals
- Easily integrate with any mobile app
- Compatible with all mobile devices
Use with any Differential Correction Source
RTK Network & Base Station
The Arrow Gold+ and Arrow Gold provide 8mm horizontal accuracy and 2cm vertical accuracy with any RTK network or local base station.
Atlas® Service
With no RTK network or base station available, the Arrow Gold+ and Arrow Gold can be used with Atlas® subscription service worldwide. Available subscriptions are H10 (4cm), H30 (15cm) and Basic H50 (30cm).
Galileo HAS
If no RTK, base station, or Atlas® service is being used, the Arrow Gold+ will work out of the box with Galileo HAS to provide 10-15 cm horizontal accuracy globally.
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. It uses the Atlas® differential corrections signals in the background while using RTK corrections. When cellular connection to your RTK network drops, SafeRTK takes over within a few seconds and allows you to maintain RTK-level accuracy. With the Arrow Gold+ and Arrow Gold, this accuracy will be retained until you are able to reconnect to your differential correction source. This enables uninterrupted RTK accuracy in spotty areas.

Determining if the Arrow Gold+ or Arrow Gold is Right for You
Customers considering the Arrow Gold GNSS receiver can now choose between the standard Arrow Gold model and the more advanced Arrow Gold+ (“plus”). The Arrow Gold+ includes all the same features of the standard Arrow Gold GNSS receiver, with additional features. The Arrow Gold+ offers 800+ channels (compared to 394 with the Arrow Gold), 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: Arrow Gold GNSS receivers cannot be upgraded to the Arrow Gold+ model. Choosing between the Arrow Gold+ and Arrow Gold is a permanent model choice
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. Along with support for Japan’s QZSS LEX signal, the Arrow Gold+ also supports Galileo E6 HAS, which provides free 10-15 cm horizontal accuracy globally.
Longer Battery Life
The Arrow Gold+ offers 11 hours of battery autonomy (increased from 7.5 hours).
Multiplexing
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.
