The MTi-680G represents the highest standard in GNSS/INS (Global Navigation Satellite System/Inertial Navigation System) with an internal, integrated Real-Time Kinematic receiver (RTK). With the MTi-680G’s added RTK feature, you can improve your positional data from meter-level to centimeter-level accuracy. You also benefit from sub 0.5 degree orientation estimates, and a rugged, IP68-rated housing at an industry-breaking price point. You can seamlessly integrate the MTi-680G in your application and it is highly flexible, with native CAN support. The MTi-680G 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 Starter Kit.
