HG3900 MEMS Inertial Measurement Unit
Overview
The next generation HG3900 IMU uses all-silicon MEMS (microelectromechanical system) technology to create a low size, weight and power (SWaP) package that performs as well or better than similar-sized IMUs using fiber optic gyroscope (FOG) or ring laser gyroscope (RLG) technology.
The HG3900 is designed and built at a Honeywell Aerospace facility in the USA. It typically has an ECCN of 7A003.d.1 but can vary depending on model selected. It generally requires an export license

Specifications
Accel Bias In-Run Stability (mg 1σ)
- 0.050
Key Benefits
- All silicon MEMS IMU with superior performance vs. similar size RLG and FOG based IMUs
- Highly robust, ruggedized to tolerate high vibration, shock and dynamic thermal environments
- Performance has been validated over full environments by U.S. Army/NTA labs
- Reduced Size & Power
- SMALLER, LOWER POWER, HIGHER PERFORMANCE IMUs than available in FOG, RLG & Quartz-MEMS based IMUs today; with RELIABLE Performance throughout the product life without repair or overhaul.
- Small size (3.1 x 3.0 inches), and low weight (less than 2 pounds)
- The HG3900 offers many factory configurable features, such as data rate output, output message protocol, and flight control filtering, to simplify system integration.
