Xsens, manufacturer of motion-tracking modules, has launched real-time-kinematic (RTK)-compatible motion trackers. The development is designed to bring centimeter-accurate positioning within reach of a new generation of affordable commercial devices.

The RTK extension to conventional satellite positioning signals reduces the maximum positioning error from around ±1 meter in standard commercial GNSS receivers to typically ±2 centimeters. Companies developing innovative new products in non-military markets such as smart farming, autonomous vehicles and coastal maritime equipment have been keen to take advantage of high-precision RTK capability to enable new applications and more automated functions, according to an Xsens press release.

The MTi-680G is a new product in the Xsens MTi 600-series. 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 also features upgraded firmware that substantially accelerates the module’s internal signal processing compared to non-RTK modules. Synchronizing 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 of devices such as drones that move at high speed, at a maximum output data rate of 400 Hz.

The RTK-enabled module also offers these features:

• 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’ MTi development kits

“Centimeter-accurate positioning at an affordable price for commercial applications — this is the promise of the new RTK-compatible MTi-680G product,” said Boele de Bie, Xsens CEO. “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.”

The MTi-680G is available for sampling now.
