LORD Sensing系列工业和战术级惯性传感器提供各种三轴惯性测量和计算姿态和导航解决方案。

在所有型号中，惯性测量单元（IMU）包括直接测量加速度，角速率和大气压力。传感器测量通过运行复杂估计滤波器或融合算法的板载处理器进行处理，以生成高精度计算输出，并提供磁性和线性加速度异常，传感器偏置，自动归零更新和噪声偏移的补偿选项。计算出的输出在不同模型之间变化，可以包括俯仰，滚转，偏航，完整的姿态和航向参考解决方案（AHRS），或完整的位置，速度和姿态解决方案（PVA），以及集成的GNSS输出。所有传感器均经过全温度补偿，并在工作温度范围内进行校准。微机电系统（MEMS）技术的使用允许高度精确，小巧轻便的设备。

LORD Sensing MIP Monitor软件可用于设备配置，实时数据监控和记录。或者，MIP数据通信协议可用于开发定制接口和简单的OEM集成。

The LORD Sensing family of industrial and tactical grade inertial 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, angular rate, and atmospheric pressure. Sensor measurements are processed through an on- board processor running a sophisticated estimation filter or fusion algorithm to produce high accuracy computed outputs with compensation options for magnetic and linear acceleration anomalies, sensor biases, auto-zero update, and noise offsets. The computed outputs vary between models and can include pitch, roll, yaw, a complete attitude and heading reference solution (AHRS), or a complete position, velocity and attitude solution (PVA), as well as integrated GNSS outputs. All sensors 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.
