The Inertial Labs Inertial Measurement Units (IMU) each contain 3 highly accurate advanced MEMS gyroscopes and 3 high performance accelerometers. To achieve maximum usability for end-users the IMU-P, and Kernel are both temperature calibrated within its operational temperature range. This also ensures tactical grade performance regardless of the environment it is being used in.

These IMU’s are a cost effective ITAR-free solution for systems that may have previously only used Fiber-Optic Gyroscopes (FOG’s) as the primary solution. By using extensive calibration methods and developing 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.

IMU Use Cases


The Inertial Labs Inertial Measurement Units have been commonly used for the following applications:

microwave antenna tower

Antenna and Line of Sight Stabilization

Stabilize unwanted antenna movement caused by wind, motion, or friction on platforms. Additionally utilize the IMU-P for it’s easy integration in 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 in both static and dynamic applications. In the aerospace industry the tactical version of the IMU-P is ideal for gimballed engines to vector thrust in different directions. Additionally, it’s commonly used in warehouses and construction sites on Mobile Elevated Work Platforms (MEWP’s) to counted and offset unwanted or unsafe tilt.

Low Cost Replacement for FOG Units

Replacing existing sensors is not as easy as purchasing a new sensor and plugging it into the existing hardware. There are many other factors that companies must consider as they seek replacement solutions, and they typically are both 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 both performance and functionality.

Electro-Optical Components (EOC and IR)

Easily integrate with electro-optical systems and use 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 angle of elevation. Response systems, utilizing 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 its 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.
