Eos Positioning Systems introduced a comprehensive RTK NTRIP app for Android that works with its Arrow line of RTK GNSS receivers. An Arrow GNSS receiver combined with the NTRIP app turns your Android smartphone or tablet into a powerful data collector capable of recording 1cm accurate GIS data in real-time.

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, Eos Tools Pro features a drop-down 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.

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