MTi-680 RTK GNSS/INS


About 

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 GNSS receiver (RTK). The MTi-680 supports RTK accuracy, which means you get access to smooth high frequency (400Hz) centimeter-level accuracy in position even in GNSS-denied environments. As a part of the MTi 600-series, this module is lightweight, robust and cost-effective. You can seamlessly integrate the MTi-680 in your application with the header facing down, directly mounted on a PCB, or as a standalone unit, with a flat cable for communication. It is also highly flexible, with native CAN support. The MTi-680 RTK GNSS/INS comes as an industrial-grade, highly affordable MEMS-based orientation sensor with an integrated sensor fusion algorithm and an easy-to-use Development Kit.
