Arrow Gold GNSS

for 1cm RTK Accuracy, SafeRTKTM

The World’s Most Advanced GNSS receiver for Every Mobile Device.

eos arrow os compatibleThe 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.
  • 1cm RTK real-time accuracy.
  • Long-range RTK Baselines up to 50 km.
  • SafeRTKTM for poor cell coverage areas.
  • World-wide satellite correction service.
  • 100% iOS, Android, Windows compatibility.


RTK Everywhere – Even in Poor Cell Coverage Areas

arrow-gold-situation-v2The 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. The Arrow Gold’s SafeRTK feature is the answer. When the Arrow Gold loses connection to the RTK network, SafeRTK takes over in a few seconds and allows the Arrow Gold to maintain RTK-level accuracy for up to 20 minutes, until the Arrow Gold is automatically reconnected to the RTK Network. This results in smooth, RTK-level 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 an 8cm, 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 10 minutes, anywhere in the world, at a revolutionary price point that works with all iOS/Android/Windows devices.

The Ultimate Accuracy for your iOS/Android/Windows Device


Of course, iOS/Android/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’s Collector/ArcPad/Survey123, and many other mobile GIS software apps.
