Inertial Measurement Units (IMU)

The Inertial Labs Inertial Measurement Units (IMU) contain three highly accurate advanced MEMS gyroscopes and three high-performance accelerometers. The IMU-P and Kernel are calibrated within their operating temperature range to achieve maximum end-user usability. This also ensures tactical grade performance regardless of the environment in which it is used.

These IMUs are a cost-effective ITAR-free solution for systems that may have previously only used Fiber-Optic Gyroscopes (FOGs) as the primary solution. Using extensive calibration methods and a robust Kalman Filter, Inertial Labs developed the IMU-P and the Kernel product lines to compete in performance with many FOG units on the market.

The Inertial Labs team of skilled engineers provides expertise to help users select and configure from the models available: IMU-P Industrial, IMU-P Tactical (Stabilization), IMU-P Tactical (Standard), and Kernel-100.

Use Cases for the Inertial Measurement Units

Antenna and Line of Sight Stabilization

Stabilize unwanted antenna movement caused by wind, motion, or friction on platforms. Additionally, utilize the IMU-P for its easy integration into antenna tracking systems. Whether you are tracking from satellites or RF transmissions, the IMU-P easily mounts to any surface and generates custom data output formats commonly used with Line of Sight (LOS) and Beyond Line of Sight (BLOS) antenna transmission systems.

Motion Control Sensors (MCS) and Gimbaled Actuators

The IMU-P is an ideal motion control solution for static and dynamic applications. In the aerospace industry, the tactical version of the IMU-P is perfect for gimballed engines to vector thrust in different directions. Additionally, it’s commonly used in warehouses and construction sites on Mobile Elevated Work Platforms (MEWPs) to count and offset unwanted or unsafe tilt.

Low-Cost Replacement for FOG Units

Replacing existing sensors is not as easy as purchasing and plugging a new sensor into the existing hardware. Companies must consider many other factors as they seek replacement solutions, which are typically costly and time-consuming. Inertial Labs wants to reduce R&D and programming time for customers seeking replacement solutions for discontinued sensors. We develop low-cost alternatives to dated FOG units by creating custom form-fitting solutions to meet end-user needs in performance and functionality.

Electro-Optical Components (EOC and IR)

Easily integrated with electro-optical systems and used for object recognition, detection, and end-to-end response systems. Commonly used in military and security divisions, Inertial Labs has partnered with many companies, such as Openworks Engineering, to develop custom solutions for target detection and response. Computer vision systems utilize data streams from the Inertial Labs IMU-P to correctly identify target position, range distance, and elevation angle. Response systems, using orientation data from the IMU-P, then take actions necessary to protect user assets.

Passenger Train Monitoring and Track Inspection Systems

Complying with EN 50121-3-2 and EN 61000-6-1/3, Inertial Labs products, particularly the Tactical Grade IMU-P, make the perfect solution for passenger train acceleration monitoring systems and track inspection payloads. Orientation data fused with optical recognition hardware and software is used to correctly identify and alert operators of potential threats to passenger safety. Whether it’s monitoring the speed and acceleration of the train or aiding in track inspections to identify crack propagation, the IMU-P ensures safety and is a critical element for all inspection platforms.

IMU Supported Software
