Honeywell has launched a new series of miniature inertial measurement units (IMUs) ruggedized to offer high accuracy along with the durability to survive high-shock environments.

Roughly the size of a water-bottle cap, the new HG1125 and HG1126 IMUs are low cost and serve both commercial and military applications.

The new family of IMUs can survive shocks up to 40,000 G-force, making it one of Honeywell’s toughest IMU products to date. The HG1125 and HG1126 can be used for a variety of defense and commercial applications such as tactical military needs, drilling, unmanned aerial vehicles or navigation systems for general aviation aircraft.

“Low-cost, ultra-rugged IMUs are in high demand across a variety of market segments where customers need high-performance navigation, but they’re limited by size or cost constraints,” said Matt Picchetti, vice president and general manager, Navigation & Sensors, Honeywell Aerospace. “Our new HG1125 and HG1126 products meet all of these requirements, making them an ideal solution for customers operating in a wide variety of high-shock environments, including everything from military tactical operations to industrial applications such as drilling.”

An IMU uses gyroscopes, accelerometers and electronics to give precise rotation and acceleration data. This enables a vehicle system to calculate where it is, in what direction it is going, and at what speed, even when GPS signals are not available.

The HG1125 and HG1126 use sensors based on micro-electromechanical systems (MEMS) technology to precisely measure motion. They are the newest IMUs from Honeywell’s tactical IMU production facility, which delivers nearly 100,000 IMUs each year to customers across a wide range of segments.

The first deliveries of these new products are set to begin in June.

Honeywell’s lineage in navigation dates to the 1920s, and it has long been a pioneer in MEMS-based IMUs. Honeywell has developed and manufactured high-performance navigation solutions found on many aircraft and other vehicles worldwide.
