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. 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

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. 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.
