Eos tools Pro Software

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. ETP is available on iOS, Android and — new as of 2020 — Windows 10.

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

  • Built-in NTRIP client to connect to an RTK Network
  • Displays accuracy and quality control related information on the position
  • Satellite View for all constellations in use (GPS, Glonass, Beidou, Galileo, QZSS)
  • User configurable alarms
  • Terminal emulator to send configuration commands to the receiver
  • Integrated Browser for HTML5 scripts
  • Real-time orthometric height conversions (choose between ellipsoidal or orthometric heights)
  • Support for Eos Locate for ArcGIS Collector, Eos Laser Mapping for ArcGIS Collector


  • Requires iOS 7.0 or later. Compatible with iPhone and iPad. Eos Tools is optimized for iPhone5, iPhone 6, iPhone 6 Plus, iPad and iPad mini.
  • Requires Android versions 4.4.2 and newer
  • Requires Windows 10 or newer

Eos Tools Pro allows you to monitor location data in the field. The app works on iOS, Android and Windows. It provides direct access to positioning information, such as PDOP, Differential Status, Satellites Tracked, and more. The app, named Eos Tools Pro, has user-configurable audible and visual alarms to alert the user of high PDOP, lost RTK correction, unacceptable correction age and several other important metrics. It supports all current and future constellations — GPS, GLONASS, Galileo and Beidou. To eliminate any confusion as to which GPS/GNSS device the user’s app is using, ETP features a dropdown menu so the user may select any receiver the Android device has been paired with. Google Maps is tightly integrated with the app to display the user’s location anywhere in the world. Detailed satellite information such as a skyplot that plots each visible satellite, whether it’s being used or not, and signal strength bar graphs from each constellation are also displayed. Finally, a Terminal screen displays the NMEA data flowing and allows the user to send commands to the receiver.

ETP and Arrow receivers are targeted at high-accuracy applications like GIS; environmental; agriculture; electric, gas, water utilities; surveying; machine control; and federal, state, and local government.
