The HG3900 delivers precise three‑axis acceleration and rotation sensing for UAVs, ground vehicles, and maritime drones, optimized for rugged operational environments. Housed in a compact cylinder under 3 in in diameter and 3.1 in tall, it offers a slender footprint of only 328 cm³ and weighs under 2 lb—making it ideal for platforms with strict SWaP demands. Its MEMS sensors are calibrated for severe temperature extremes (–54 °C to +85 °C), ensuring uninterrupted navigation in arctic cold or desert heat. Typical power draw is just 2.5 W, with a maximum of 6 W, enabling efficient integration with battery‑powered systems while maintaining continuous precision.

Engineered for seamless system integration, the HG3900 provides stable inertial data for autonomous guidance, stabilization, and sensor fusion applications. Its robust housing and low electrical profile make it suitable for military‑grade environments, including GNSS‑denied or signal‑contested scenarios. Firmware compatibility with common navigation toolkits simplifies deployment, while the unit’s high full‑scale ranges and low drift support extended missions requiring enduring attitude and heading reference. The HG3900 bridges laboratory performance and field readiness, empowering defense developers to deploy reliable navigation across multiple unmanned platforms.
