Xsens 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.
The new MTi-680G, a new product in its MTi 600-series, also features upgraded firmware which substantially accelerates the module’s internal signal processing compared to non-RTK modules. Synchronizing the global position coordinates with the module’s altitude, heading and velocity outputs, the MTi-680G can provide a comprehensive positioning and navigation output for any carrier device, including of devices such as drones that move at high speed, at a maximum output data rate of 400Hz.
The RTK-enabled module also offers other features which make it stand out from the competition:
- Precise factory calibration of every production unit
- High immunity to magnetic interference
- Adaptive firmware operation to optimize performance in various types of scenario
- Easy-to-use, free MT Software Suite developer tools to accelerate integration into end product designs
- Out-of-the-box operation with Xsens’ popular MTi development kits
Boele de Bie, Xsens’ CEO, said: ‘Centimeter-accurate positioning at an affordable price for commercial applications – this is the promise of the new RTK-compatible MTi-680G product. From seed-sowing agricultural robots to autonomous cargo ships, a whole new generation of applications is now possible thanks to the centimeter-level accuracy of the MTi-680G’s position measurements.’
