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). The Arrow Gold+ works with all off-the-shelf mobile apps.
The Arrow Gold+ includes all the same features of the now-retired Arrow Gold® GNSS receiver, with additional ones. 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 Arrow Series® GNSS receiver that Eos Positioning Systems® offers.
Even More Features with Arrow Gold+
Even More Signals Supported
Incredible signal support results in faster RTK convergence and better RTK performance in tough conditions. Additional signals include the concurrent use of the BeiDou B3 and GPS L5; Japanese LEX; Galileo E6 HAS; and even more GLONASS, BeiDou, QZSS and IRNSS signals.
Longer Battery Life
The Arrow Gold+ offers 11 hours of battery autonomy (increased from 7.5 hours).
Bluetooth® Bridge
Connect your Arrow Gold+ to any non-Bluetooth third-party sensor to 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, such as two iPad®s, to a single Arrow Gold+ receiver. This is ideal for training.
Use with any Differential Correction Source
RTK Network & Base Station
The Arrow Gold+ provides 8mm horizontal accuracy and 2cm vertical accuracy with any RTK network or local base station.
Atlas® Service
When no RTK corrections are available, the Arrow Gold+ may 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 select Eos GNSS receivers including the Arrow 300+®. Whenever cellular connection to your RTK network drops, SafeRTK takes over instantly and allows you to maintain RTK-level accuracy. It does so by drawing on powerful, worldwide, satellite-based Atlas signals in the background. Your survey-grade accuracy will be retained for up to 20 minutes, giving you time to reconnect to your differential correction source. This enables uninterrupted RTK accuracy in spotty areas.
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 one of our most efficient GNSS receivers, 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
The Arrow Gold+ is agnostic, hence compatible with all consumer mobile devices and any third-party data collection apps.
Arrow Gold+ Base Station
The Arrow Gold+ base station configuration allows you to install and operate your own base station where there is no RTK network or base station available. An Arrow Gold+ base station offers four-constellation GNSS support for high accuracy and productivity. Our team can help you with your installation. Contact Eos to discuss if this is an appropriate option for your application.
