Xsens Technologies (Enschede, The Netherlands) has launched a new RTK (Real-Time Kinematics)-compatible inertial motion tracker with centimetre-level accuracy – the MTi-680G.

The RTK 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 and provides synchronised 3D attitude (tilt, inclination) and heading outputs.

The new device also features upgraded firmware, which substantially accelerates its internal signal processing, compared with non-RTK modules. Synchronising the global position coordinates with the module’s attitude, heading and velocity outputs, the MTi-680G can provide a comprehensive positioning and navigation output for any carrier device (including fast-moving devices such as drones) at a maximum output data rate of 400Hz.

Additional features which make it stand out from the competition include:

  • Precise factory calibration of every production unit;
  • High immunity to magnetic interference;
  • Adaptive firmware operation to optimise performance in various scenarios;
  • 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.

 “Centimetre-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 centimetre-level accuracy of the MTi-680G’s position measurements,” commented company CEO, Boele de Bie.
