PHOENIX, Ariz. Honeywell has launched a new series of miniature inertial measurement units that are ruggedized to offer accuracy along with the durability to survive high-shock environments. The new HG1125 and HG1126 inertial measurement units (IMUs) are designed to serve both commercial and military applications.

According to the company, the new family of IMUs is designed to survive shocks up to 40,000 G-force. These IMUs can be used for tactical military needs, drilling, unmanned aerial vehicles, or navigation systems for general aviation aircraft.

Officials claim that an IMU uses gyroscopes, accelerometers, and electronics to give precise rotation and acceleration data. This enables a vehicle system to calculate where it is, 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 measure motion. The HG1125 and HG1126 are the newest IMUs from Honeywell's tactical IMU production facility. The first deliveries of these new products are set to begin in June 2021.
