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 industrybreaking price point. You can seamlessly integrate the MTi-680G in your application and it is highly flexible, with native CAN support.

The MTi-680G is an RTK enabled GNSS/INS with a rugged housing featuring IP68 protection against environmental influences. Building on the proven MTi 600-series technology it enables a robust and easy to use cm-level positioning and orientation tracking. It features an incredibly powerful onboard u-blox ZED F9 RTK GNSS receiver to provide superior positioning performance. It is designed for easy integration and seamless interfacing with other equipment. Technical specifications
