Xsens launches the MTi-680G, a full-featured rugged module with internal RTK receiver.

The new MTi-680G brings centimeter-accurate positioning capability within reach of a new generation of affordable commercial devices with the launch of new RTK-compatible inertial motion trackers.

The RTK (Real-Time Kinematics) extension to conventional satellite positioning signals reduces the maximum positioning error from around ±1m in standard commercial GNSS receivers to typically ±2 cm. The MTi-680G, an integrated GNSS/Inertial Navigation System (INS) module, features an integrated RTK GNSS receiver, as well as providing synchronized 3D attitude (tilt, inclination) and heading outputs.
