Designed for harsh environments that include magnetic, dynamic, and temperature fluctuations as well as high shock and humidity, our inertial sensors and acoustic sensors deliver exacting performance. Our knowledgeable engineering team and decades of experience ensure our portfolio of inertial sensors perform in your application.


Laser Targeting


In situations where precision is an absolute must, Sparton delivers the inertial sensors that can be trusted time and time again. Our products have been built to improve on today’s product standards with even greater performance than is required for tomorrow’s laser targeting systems.

Satellite Communications


Panning the sky in search for satellite signals takes on a whole new meaning in urgent conditions when time is of the essence. Getting your connections established in short order requires absolute accuracy—accuracy that can only be delivered by Sparton’s inertial sensor systems.

Unmanned Vehicles


Unmanned vehicles continue to impress with rapid advances in technology that make these vehicles suitable for military and commercial use. The inertial sensor is a critical component for unmanned operation success, and Sparton is lock step in the rapid development of sensor system technologies for air, sea and ground.

Industrial Applications


Exploring the vast ocean floor for oil and gas opportunities is a daunting task. Sparton’s inertial sensor product offerings help produce the critical accuracy needed to survey, collect and analyze the sea floor to mine these natural resources.

Featured Inertial Sensors

Laser Targeting, Oil and Gas Exploration, Oceanography and more. Whatever your application, our inertial sensor systems can meet your most demanding needs.


Harsh environmental conditions, extreme magnetic interference, mechanical shock and transient platform vibrations all contribute to the challenge of high accuracy inertial sensing and platform attitude reporting. Sparton IMU-10 inertial sensing system thrives in such environments and provides end-users with a reliable high-performance, high-accuracy 10DOF inertial sensing package in a ruggedized enclosure.


By eliminating nearly all external magnetic disturbances that affect heading accuracy, the Sparton GEDC-6E AHRS provides highly dynamic response features combined with long-term stability and accuracy. An enhanced version of our GEDC-6, it has a faster start-up time and in-field calibration convergence.


Fully temperature compensated, the AHRS-8 is individually calibrated for industry-leading heading accuracy. Our AdaptNav II™ algorithm provides accurate in-field calibration, while the NorthTek™ Development System makes it the world’s only fully programmable inertial system.

The World Magnetic Model and Inertial Sensor Systems

The World Magnetic Model (or WMM) is a large spatial-scale representation of the earth’s magnetic field that impacts the accuracy of compasses, especially Digital Magnetic Compasses (DMCs) – a type of inertial sensor. The WMM is the standard model used for navigation. The model is used by the US Department of Defense, the UK Ministry […]

What is an AHRS?

An Attitude Heading and Reference System, better known as an AHRS, is a 3-axis sensor system that provides real-time 3D attitude position – pitch, roll, and heading. The primary function then of an AHRS is to provide orientation data. AHRS are designed to replace traditional gyro-based instruments and to provide superior reliability and accuracy. Some […]
