The LORD Sensing 3DM-GX5 family of high-performance, industrial-gradeinertial sensors provides a wide range of triaxial inertial measurements and computed attitude and navigation solutions.

In all models, the Inertial Measurement Unit (IMU) includes direct measurement of acceleration and angular rate, and are fully temperature-compensated and calibrated over the operating temperature. The use of Micro- Electro- Mechanical System (MEMS) technology allows for highly accurate, small, lightweight devices.

The  LORD Sensing  MIP Monitor software can be used for device configuration, live data monitoring, and recording. Alternatively,  the MIP Data Communications Protocol is available for development of custom interfaces and easy OEM integration.

Product Highlights

  • Triaxial accelerometer, gyroscope, temperature sensors achieve the optimal combination of measurement qualities

The LORD Sensing 3DM-GX5® family of high-performance industrial grade inertial sensors provides a wide range of triaxial inertial measurements and computed attitude and navigation solutions. The 3DM-GX5-45 all-in-one navigation solution features a high performance integrated multi-constellation GNSS receiver utilizing the GPS, GLONASS, BeiDou, and Galileo satellite constellations. Sensor measurements are fully calibrated, temperature-compensated, and mathematically-aligned to an orthogonal coordinate system for highly accurate outputs. The auto-adaptive estimation filter algorithm produces highly accurate computed outputs under dynamic conditions. Computed outputs include pitch, roll, yaw, heading, position, velocity, and GNSS outputs- making it a complete GNSS/INS (GNSS Aided Inertial Navigation System) solution. The use of Micro-Electro-Mechanical System (MEMS) technology provides a highly accurate, small, light-weight device. The LORD Sensing MIP Monitor software can be used for device configuration, live data monitoring, and recording. Alternatively, the MIP Data Communications Protocol is available for development of custom interfaces and easy OEM integration.
