Product overview
The Wuxi Beiwei Sensing Technology BW-98A is a high-precision, single-axis fiber-optic gyroscope for navigation, payload attitude determination, and positioning and orientation systems. Its applications include unmanned aircraft, airborne navigation, ships and land positioning. The sensor has a diameter of 98mm and a height of 28mm, with a specified dimensional envelope of ≤98mm × 98mm × 28mm and weight of ≤560g. Its electrical configuration uses a +5VDC supply and an RS422 interface, with interface customization available. Power consumption is ≤5W.
The BW-98A measures angular rates over ±100º/s, with resolution of 0.002 º/h and bias stability of ≤0.006 º/h under the specified 1σ, 10s condition. Scale factor relative error is ≤50ppm, and its 3dB dynamic response bandwidth is ≥500Hz. Operating temperature extends from -45℃ to +70℃, while storage temperature spans -55℃ to +85℃. Maximum vibration tolerance is 18g, and maximum shock tolerance is 100g for a 6ms half-sine pulse. Additional applications include low-altitude crewed aircraft, aviation and rail inspection.
