LORD Microstrain Develops Miniature Inertial Sensors for Unmanned Systems

Published: 26 Aug 2018 | Author: Mike Rees

LORD Microstrain, a leading developer of innovative miniature high-performance inertial sensors for UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles) and other robotic platforms, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Gold’ profile highlights how their advanced inertial sensing solutions can support a wide array of unmanned systems applications in both the defense and commercial sectors.

3DM-CV5-25 Attitude and Heading Reference System (AHRS)The 3DM-CV5-10 Vertical Measurement Unit is LORD’s smallest, lightest and highest performance IMU in its class. The industrial-grade board-level unit incorporates a triaxial accelerometer, gyroscope, and temperature sensors to provide an optimal measurement combination that is mathematically aligned to an orthogonal coordinate system for superior accuracy. IMU outputs include acceleration, angular rate, delta theta and delta velocity.

The 3DM-CV5-25 is a complete Attitude and Heading Reference System (AHRS) solution that provides IMU outputs (acceleration, angular rate, magnetic field, ambient pressure, delta theta, delta velocity) as well as a wide variety of computed outputs. A state-of-the-art Extended Kalman Filter run by dual on-board processors delivers high-accuracy dynamic attitude estimates.

3DM-GX5-25 Attitude and Heading Reference System (AHRS)The 3DM-GX5-25 is LORD’s high-performance industrial-grade Attitude and Heading Reference System that provides the same outputs as the 3DM-CV5-25 but with greater stability and lower noise density. Automatic magnetometer calibration and anomaly rejection eliminate the need for field calibration, saving time as well as effort and allowing for quick and easy system integration. The unit also automatically compensates for noise and vibration, making it ideal for the harsh environments of unmanned vehicle operations.

The 3DM-GX5-15 Vertical Reference Unit uses a triaxial accelerometer, triaxial gyroscope, temperature sensors, and pressure altimeter to provide both IMU outputs (acceleration, angular rate, ambient pressure, delta theta, delta velocity) as well as a wide variety of computed outputs. A state-of-the-art Extended Kalman Filter run by dual on-board processors delivers high-accuracy dynamic attitude estimates.

The 3DM-GX5-45 is a complete high-performance GNSS-aided navigation solution with a multi-constellation receiver that is compatible with GPS, GLONASS, BeiDou, and Galileo satellite constellations. The state-of-the-art auto-adaptive estimation filter algorithm produces highly accurate computed pitch, roll, yaw, heading, position, velocity, and GNSS outputs under highly dynamic conditions. The blended GNSS and INS outputs provide high-accuracy position estimation for a variety of unmanned systems.
