Xsens INS module uses GNSS for positioning

US: Xsens has expanded its MTi product portfolio with the introduction of the MTi-7, a miniature inertial navigation system (INS) module that uses input from an external GNSS receiver to provide an accurate, real-time position, velocity and orientation data stream.

The module has a compact 12 x 12-millimeter footprint, weighs less than 1 gram and consumes under 100 milliwatts, making it suitable for use in space- and power-constrained devices such as drones, as well as autonomous or remote-controlled mapping and imaging equipment.

Operating at output data rates up to 800 Hz, the MTi-7 achieves very low latency of 2 milliseconds, allowing for real-time operation of dynamic functions such as flight control and camera stabilization, the company said.

The module also offers a position and velocity output suitable for the navigation of autonomous ground vehicles in sectors such as smart farming and robotics.

The high performance of the MTi-7 is due to the advanced sensor fusion algorithms developed by Xsens to synchronize the inputs from the module’s onboard accelerometer, gyroscope and magnetometer with the signals from an external GNSS receiver or barometer.

The raw sensor signals are combined and processed at high speed in the MTi-7 module to produce a real-time data stream showing the device’s horizontal and vertical position, velocity, roll, pitch and yaw. This user-friendly data stream may be supplied to a host processor via a standard I2C, SPI or UART interface.

Based on the design of the successful MTi 1-series, the MTi-7 offers a straightforward upgrade path for current MTi-1 users on the same form factor. It is also able to provide heading, positioning and orientation accuracy more commonly found in much larger, heavier and higher power devices.
