Arrow Gold SafeRTK

/ / Arrow Series

for 1cm RTK Accuracy, SafeRTKTM

World’s Most Advanced GNSS Receiver for Every Mobile Device

eos arrow os compatible

The Arrow Gold is the first high-accuracy iOS, Android, and Windows Bluetooth GNSS receiver to implement all four global constellations (GPS, GLONASS, Galileo, BeiDou), three frequencies (L1, L2, L5) and satellite-based RTK augmentation. The Arrow Gold works with all apps that run on iOS, Android, and Windows devices. It also supports all planned global satellite constellations as well as all planned signals, giving it an awesome return on investment that will serve you well into the next decade and beyond.


Key Features

  • Supports GPS, GLONASS, Galileo, BeiDou, QZSS
  • Triple-frequency L1/L2/L5
  • 1 cm RTK real-time accuracy
  • Long-range RTK baselines up to 50 km
  • SateRTK for poor cell coverage areas
  • Worldwide satellite correction service
  • 100 % iOS, Android, and Windows compatibility


RTK Everywhere – Even in Poor Cell Coverage Areas


The Arrow Gold offers a new feature called SafeRTK. There’s nothing more frustrating than trying to stay connected to an RTK network in areas with poor cell coverage. This feature is the answer. When the Arrow Gold loses connection to the RTK network, SafeRTK takes over in a few seconds and allows it to maintain RTK-level accuracy for up to 20 minutes, until the Arrow Goldis automatically reconnected to the RTK network. This results in smooth, RTK accuracy even in areas with poor cell coverage.

No RTK Network Access Available? Pioneering Low-Cost Global Satellite

Do you work in an area without an RTK network available? The Arrow Gold features a 4 cm, real-time satellite correction service available anywhere in the world. Using all four constellations and signals, the Arrow Gold offers convergence times as low as 15 minutes anywhere in the world, at a revolutionary price point that works with all iOS, Android, and Windows devices.

The Ultimate Accuracy for your iOS, Android, or Windows Device


Of course, iOS, Android, and Windows compatibility is our expertise Eos has the most advanced connectivity with all mobile devices and free software utilities to ensure compatibility with apps like Esri Collector, ArcPad, Survey123, and many other mobile GIS software apps.
