MTi-680 RTK GNSS/INS

The MTi-680 meets the highest standards in miniature MEMS-based GNSS/INS products.

MTi-680 RTK

An industry-leading development platform

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.

Smooth high-frequency

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

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.
