General Description
The MTi-G-710 GNSS/INS from Movella offers a solution for precise motion tracking and positioning. Designed for applications in challenging environments, this sensor module combines a GNSS receiver with an inertial measurement unit (IMU) to provide high-resolution position, velocity, acceleration, and orientation data, making it ideal for applications requiring robust motion tracking and navigation.
This lightweight module features an integrated multi-sensor platform, including gyroscopes, accelerometers, magnetometers, and a barometer, all processed using advanced sensor fusion algorithms. These components ensure precise, real-time orientation and navigation in dynamic conditions. The system supports various interfaces like USB, RS232, and RS422, allowing seamless integration into diverse platforms.
The MTi-G-710 is supported by the MT Software Suite which includes MT Manager (GUI for Windows/Linux). Data is transmitted to external systems at up to 2 kHz or stored for post-analysis. With its compact design, low power consumption, and rugged build equivalent to IP67 standards, the MTi-G-710 is ideal for both laboratory and field use.
Research Areas
The motion sensor is a highly valuable tool for transportation research, particularly in areas that require precise position, orientation, and motion analysis. One key research area is in Advanced Driver Assistance Systems (ADAS) and autonomous driving. The sensor’s high-accuracy GNSS and inertial data enable detailed evaluations of vehicle dynamics and trajectory.
Another significant application is in Driver Behaviour and Performance. The motion sensor can monitor vehicle behaviour during critical manoeuvres, such as braking, turning, or accelerating, providing insights into safety risks at intersections, roundabouts, and other complex road geometries. It also facilitates studies on driver responses to adverse weather, road curves, and grades, which can be used to refine road designs and safety protocols.
