Product overview
The Beiwei Sensing BW-320A is a medium-accuracy, digital closed-loop fiber-optic gyroscope for single-axis angular-rate measurement. Its intended roles include airborne navigation, payload attitude determination, and positioning and orientation systems for unmanned aircraft, ships and land applications. The hardware uses an all-solid-state structure with integrated optical and electronic packaging and no rotating parts. This architecture incorporates vibration resistance and magnetic-field resistance. The product is a sensing component for integration into a larger system, rather than a flight platform or airframe kit.
The BW-320A occupies an envelope of ≤59.6mm×59.6mm×26.3mm, weighs ≤150g and has a 4-φ4.2mm mounting specification. Electrical integration requires +5VDC, with power consumption of ≤4W and an RS422 interface that can be customized. Its measurement range is ±530º/s, with bias stability of ≤0.1º/h under the stated 1σ, 10s condition. Operating temperature extends from -45℃ to +70℃; storage temperature extends from -55℃ to +85℃. Mechanical limits include 18g maximum vibration and 100g shock for a 6ms half-sine pulse.
