Eos Tools Pro

Eos Tools Pro is a professional GNSS monitoring utility designed for surveyors and GIS professionals using Arrow and Skadi Series High-Precision GPS receivers from Eos Positioning Systems. Unlock the full potential of your positioning hardware with real-time access to critical GNSS data that drives accurate survey and mapping workflows.

Real-time positioning intelligence puts you in control. Monitor advanced GNSS metrics including RMS values, PDOP, differential status, and satellite constellation tracking—all essential for submeter and centimeter-level accuracy in field data collection. View comprehensive satellite information across GPS, GLONASS, BeiDou, Galileo, and QZSS constellations to understand your positioning environment at a glance. The app displays both GNSS and tilt compensation accuracy with quality control indicators, enabling you to validate data confidence before collection.

Streamline RTK and DGNSS workflows with the built-in NTRIP client. Connect directly to RTK networks without switching applications, maintaining seamless access to correction services while your mapping or surveying software runs in the foreground. Eos Tools Pro operates silently in the background, delivering positioning metadata through Location Extras and mock location providers, so your workflow stays uninterrupted. Configure audible alarms to alert you to positioning threshold changes—critical when working in challenging environments or monitoring data quality shifts.

Advanced positioning features empower professional-grade work. Select Skadi Smart Handle modes including Extensible Virtual Range Pole or Invisible Range Pole to match your surveying methodology. Compute and apply position shifts to accommodate multiple antenna positions on your receiver. Apply orthometric height corrections using integrated geoid models for accurate vertical datum transformation. For laser-based workflows, leverage laser offset mapping integration with Esri ArcGIS Field Maps to enhance your spatial accuracy.

For developers, Eos Tools Pro includes an integrated HTML5 browser to run custom apps, with Location Extras support for passing valuable GNSS metadata to location services. A terminal emulator lets you send configuration commands directly to your receiver for advanced setup and troubleshooting. Comprehensive online documentation and sample code are available to guide integration and customization.

Eos Tools Pro requires an Arrow or Skadi GNSS receiver—it does not work with your device's internal GPS. Background operation may impact battery life. Compatible with Android 5.0 and newer.
