Eos Tools Pro App Icon GPS GIS GNSS

Eos Tools Pro is a free GNSS monitoring application from Eos Positioning Systems. Eos Tools Pro is compatible with Arrow Series® GNSS receivers and Eos solutions. With Eos Tools Pro, mobile workers can monitor GNSS metadata (e.g., PDOP, RMS, differential status, satellites tracked/used) in real time. Eos Tools Pro also enables connection to RTK networks and base stations through its built-in NTRIP client. In addition, Eos Tools Pro offers advanced features, such as configurable alarms and real-time GEOID height conversions. Eos Tools Pro is also the main app used in a number of Eos solutions, including Eos Locate™ and Eos Laser Mapping™, both for ArcGIS apps. Please note Eos Tools Pro does not collect data. For data-collection apps, we recommend a variety of partner apps.

Monitor GNSS Status

Monitor important GNSS metadata — such as estimated accuracy, differential fix status, PDOP, HDOP, and number of satellites tracked — for real-time QA/QC.

Stream RTK Locations

With its built-in NTRIP client, Eos Tools Pro lets you connect to any RTK network or base station and stream centimeter-level positions to your own data-collection app.

Set Alarm Thresholds

Audible and visual alarms notify you when a condition, such as a high estimated accuracy, falls outside acceptable thresholds.

Set Datum Shifts

Eos Tools Pro allows you to apply a real-time datum shift to your Arrow coordinates to match your map datum.

Calculate Orthometric Heights

Eos Tools Pro optionally outputs practical orthometric heights for you, by converting from ellipsoidal heights using regional GEOID models on the fly.

Set Antenna Height

If your data collection app has no provision to set an antenna height, Eos Tools Pro offers this possibility and streams accurate elevations directly to your map.

Eos Tools Pro: Added Value

Available on All Devices

Eos Tools Pro is available for iOS, Android, and Windows devices.

App Friendly

Eos Tools Pro can support any third-party app (e.g., from existing Eos partners or even your own proprietary app).

Supports Eos Solutions

Eos Tools Pro is the main app used to take advantage of Eos solutions, such as Eos Locate™ for ArcGIS and Eos Laser Mapping™ for ArcGIS.

Easily Connect to RTK

Eos Tools Pro supports all RTK networks and base stations

Eos Tools Pro has a built-in NTRIP client that allows you to connect to any available RTK network or base station.

RTK network: Oftentimes, local government bodies (e.g., DOTs) maintain a free RTK network with logins available upon request. Other times, there is a paid RTK network available. Eos can help you determine if a network is available in your area.

Base station: In addition, Eos Tools Pro can be used to log in to your own  or any other base station. If you don’t have an available base station, Eos can help you determine if it is cost effective to install an Arrow Gold® base station at your facility or bring a portable base station to your work site.

Monitor GNSS Metadata Live

With real-time GNSS monitoring, you can ensure that only the highest quality data is being used in your mobile workflow. GNSS metadata fields are important markers of how accurate your data was when it was collected. It also lets you track the number of satellites available and used, and which differential correction status is being used (e.g., DGPS, RTK Fixed, RTK Float). Accessing these GNSS metadata live lets you control location quality live. In addition, many companies partner with Eos so that these metadata fields can be captured within popular third-party apps, providing a glimpse back in time to the conditions in which your location data was captured.

Set Survey-Grade Elevations

Eos Tools Pro offers the possibility to output survey-grade elevations directly to your app of choice. When orthometric height is selected, Eos Tools Pro uses your local GEOID model to convert the default GNSS elevation measurements from ellipsoidal to orthometric heights. The Arrow receiver will output these accurate GNSS elevations into any data-collection app. Eos offers several resources to help you get started with real-time survey-grade elevations.

Access Eos Solutions

Eos Tools Pro is the main app that houses all Eos solutions:

  1. Eos Locate™ for ArcGIS allows you to map underground utilities live into an Esri ArcGIS environment.
  2. Eos Laser Mapping™ for ArcGIS lets you map assets from afar when they are located in unsafe or GNSS-impaired environments.
