Operating principle and key features

The EFT M3 Plus receiver determines coordinates using signals from satellite navigation systems. Built-in algorithms process triple frequency signals for reliable positioning even in high-rise buildings. An inertial tilt sensor (IMU) automatically corrects coordinates when the pole is tilted up to 60 degrees. RTK+ technology allows you to obtain accurate coordinates even in the absence of a fixed solution.

Support for the IRTK service makes it possible to work through a cloud server, uniting several field teams from one base. The built-in VHF modem with a power of 2 W ensures the transmission of corrections at a distance of up to several kilometers. Wi-Fi and Bluetooth allow you to connect to controllers and smartphones. The NFC tag simplifies pairing with EFT field controllers. The web interface makes it possible to configure the device remotely via a browser.

The EFT M3 Plus receiver is ideal for geodesy, cadastral work, construction, monitoring and engineering surveys. High accuracy, reliability and complete protection from external influences make it an indispensable tool in the harshest conditions.
