Precision Inertial Sensors and Systems: IMU, GPS-INS, AHRS, MRU

The IMU-P is a light-weight and compact high performance Inertial Measurement Unit (IMU), designed for a number of applications including UAV and AUV/ROV navigation and control.

The unit contains three highly accurate Advanced MEMS gyroscopes and three ultra high performance accelerometers for precise linear acceleration and angular rate measurements.

The IMU-P is an ITAR free inertial solution, that is fully calibrated and compensated over its operating temperature range. Both Industrial and Tactical grade units are available.

Compact size (39 x 45 x 22 mm) and low weight (70 gram) – ideal for integrated system applications.

The OS3D-FG is a miniature Attitude and Heading Reference System (AHRS) designed for real-time orientation tracking applications. It fuses data from tri-axial MEMS gyroscopes, tri-axial MEMS accelerometers and tri-axial fluxgate magnetometers using an onboard Digital Signal Processor and state-of-the-art algorithms.

The OS3D-FG is ideal for a wide range of small unmanned vehicles, including UAVs, ROVs and ground robotics.

The OS3D-DTS is an ultra-high accuracy, miniature dual axis MEMS Digital Tilt Sensor, designed for precision tilt measuring. It includes tri-axial MEMS Gyroscopes and tri-axial high precision MEMS Accelerometers; and is equipped with an onboard processor and embedded inclination and tilt algorithms allowing for direct integration into systems without interfacing a PC.

The low-SWaP, ITAR-free OS3D-FG is environmentally sealed (IP67) in a rugged enclosure, making it ideal for a wide range of unmanned applications, including UAVs, Robotics and Electro Optical Systems.

The AHRS-10 is a high-accuracy AHRS that outputs absolute orientation (heading, pitch and roll) for both motionless and dynamic applications. It integrates precision 3-axis accelerometers, magnetometers and gyroscopes to provide absolute pitch and roll data, real time device rotation data and ongoing gyroscope corrections.

The AHRS-10 utilizes our high-performance Fluxgate Magnetometer technology for superior stability and repeatability, making it an ideal solution for unmanned systems applications where superior accuracy is required.

The AHRS-II is our family of next-generation AHRS featuring state-of-the-art algorithms for a wide range of dynamic motions of unmanned vehicles. Precision 3-axis accelerometers, magnetometers and gyroscopes provide heave, heading, pitch and roll data, as well as high-frequency real time device rotation data and ongoing gyroscope corrections.

OptoAHRSTM-II works through the use of reference images. A reference image is literally a picture of the horizon in a given direction. Within the reference image the system identifies a constellation of identifiable features.
