Inertial Labs, a VIAVI solutions company, has introduced the IMU-H100, a micro-electromechanical systems (MEMS) inertial measurement unit (IMU) designed to improve the tactical guidance and navigation capabilities of unmanned aerial vehicles (UAVs), short-range missiles, precision guidance munitions, and a variety of commercial applications. 
As autonomous vehicle technology advances and personnel safety becomes a primary priority, the military and commercial sectors accelerate adoption, resulting in high demand for the IMUs that power their navigation and control systems.
An IMU measures angular velocity and linear acceleration with MEMS gyroscopes and accelerometers, respectively.
They have proven indispensable in a variety of guidance and navigation, orientation, and stabilization applications, notably for short- and medium-range flight control systems.
The IMU is also used in higher-level systems including inertial navigation systems (INS), attitude and heading reference systems (AHRS), and motion reference units (MRU). Autonomous vehicles are used on land, at water, in aerospace, and military.
The Tactical-Grade IMU-H100 Includes:
- Accelerometers and gyroscopes for all three axes and offers a gyro and accel bias of 1 deg/hr and 1 mg respectively.
The 5 in3, 160 g IMU also exceeds the performance of equivalent products on the market in terms of data rate, measurement range, stability and repeatability over harsh environmental conditions – including vibration, shock, high acceleration, spinning, temperature and acoustic noise.
In addition to its sophisticated capabilities, the IMU-H100 is Designed For:
- Ease and speed of integration into customers’ operations.
- It supports the Universal Asynchronous Receiver/Transmitter (UART) and Synchronous Data Link Control (SDLC) used in many legacy systems, making it ideal for retrofitting initiatives.
- It is also ITAR-free, available with a lead time of weeks rather than months, and is manufactured in the United States.
Leadership Comments
“The IMU-H100 is the latest addition to our large family of tactical-grade IMUs and couples an exceptional gyro and accelerometer repeatability bias with industry-leading performance and ruggedness,” said Jamie Marraccini, Vice President, Inertial Labs Products, VIAVI. “Its design builds on over 20 years of innovation and enables the guidance and stabilization required by both the commercial sector and aerospace and defense applications worldwide.”
