Eos Tools Pro is a monitoring utility for the Arrow and Skadi series high precision GNSS receivers from Eos Positioning Systems. 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 end trip client to access RTK or DGNSS corrections from an RTK network. Eos Tools Pro also allows audible user configurable alarms and runs in the background of your mapping surveying software. Features: - Built-in NTRIP client to connect to an RTK Network - Displays GNSS and Tilt Compensation accuracy with quality control information - Select the Skadi Smart Handle mode: Extensible Virtual Range Pole™ or Invisible Range Pole™ - Satellite view for all constellations in use (GPS, GLONASS, BeiDou, QZSS and IRNSS) - User configurable alarms - Orthometric Height (Geoid models for vertical datum) - Compute and apply Position Shifts to accommodate different - Laser Offset Mapping for Esri ArcGIS® Field Maps - Locate and map underground utility assets directly in ArcGIS Field Maps - Terminal emulator to send configuration commands to the receiver - HTML5 built-in browser Disclaimer: "Continued use of Eos Tools Pro running in the background and connected to the GPS/GNSS receiver can dramatically decrease the battery life of your Apple device."
