About Eos Tools Pro

Eos Tools Pro is a monitoring utility for the Arrow Series receivers from Eos Positioning Systems®, Inc. (Eos). It provides advanced GNSS information such as RMS values, PDOP, Differential Status, Satellites Tracked and Used, that are critical for submeter and centimeter GIS and Surveying data collection.

The app features a built-in NTRIP client to access RTK or DGNSS correction from an RTK Network. Eos Tools Pro also allows audible user configurable alarms and runs in the background of your mapping/surveying software.

Key Features
