Product overview
The BWSENSING BW-98A is a high-precision single-axis fiber-optic gyroscope intended for navigation, payload attitude determination, and positioning and orientation systems. Its applications include unmanned aircraft, airborne navigation, ships, land positioning, low-altitude crewed aircraft and rail inspection. The sensing specification combines a ±100º/s measurement range with 0.002 º/h resolution and scale factor relative error of ≤50ppm. Bias stability is ≤0.006 º/h at 1σ, 10s, and the 3dB dynamic response bandwidth is ≥500Hz.
For physical integration, the BW-98A has specified overall dimensions of ≤98mm×98mm×28mm and weighs ≤560g. Its diameter-and-height dimensions are also given as 98mm × 28mm. The electrical configuration requires +5VDC, consumes ≤5W and uses an RS422 interface, with customization available. Operating temperature extends from -45℃ to +70℃, and storage temperature from -55℃ to +85℃. The mechanical limits are 18g maximum vibration and 100g maximum shock with a 6ms half-sine pulse.
