MTi-680 RTK

An industry-leading development platform

Icon of a star within a circle
Highest standard in GNSS/INS

The MTi-680 represents the highest standard in GNSS/INS (Global Navigation Satellite Systems/inertial navigation systems) when connected to an external real-time kinematic (RTK) GNSS receiver. 


Icon of an equaliser frequency
Smooth high-frequency

It supports RTK GNSS receivers, resulting in smooth high-frequency (400 Hz) centimeter-level position accuracy, even in challenging environments.

Icon of two cogs
Easy to integrate, with native CAN support

It’s lightweight and robust, as well as cost-effective and easy to integrate in your choice of two ways: either with the header facing down, directly mounted on a PCB, or as a standalone, with a flat cable for communication.

Free to download MT Software Suite

The MT Software Suite provides everything you need to make the most of your MTi-680. It contains a specially developed, easy-to-use graphical user interface, as well as drivers for various operating systems, for example, and source code.

The suite comes with complete documentation. Of course, you can also always contact our technical support staff if you have questions.

The MT Software Suite includes different software programs, such as:

Icon representing MT Manager MT Manager (GUI)

This provides you with easy access to all the functions of your MTi from the comfort of your office. MT Manager enables recording and playback of data, real-time data viewing, including graphs, and easy configuration of settings. 

Icon representing code language MT SDK

This program is for self-developing your software to communicate with our sensor, including programming examples for C, C++, C#, MATLAB, Python, ROS, and Nucleo/STM boards. 

Icon representing a magnetic field mapper Magnetic Field Mapper

Magnetic Field Mapper (MFM) is a calibration tool for conducting magnetic calibration, available as GUI for Windows and as SDK.
