Product overview
The BWSENSING GI2100 is a high-precision fiber-optic integrated navigation system intended for UAV and unmanned-vessel navigation and control. Its applications also include railway inspection vehicles, antenna stabilization, spatially stabilized platforms, attitude and azimuth reference systems, and multibeam attitude sensing. Further uses include intelligent navigation and control for tunneling and mining machinery. Overall dimensions are 260 mm long, 260 mm wide and 280 mm high. The gyroscope has a ±1000°/s measurement range and bias stability of ≤0.01°/h; the accelerometer has a ±30 g range and bias stability of ≤30 ug.
Navigation accuracy depends on the integration and alignment configuration. Heading accuracy is ≤0.05 deg RMS with single-antenna dynamic alignment, or ≤0.1 deg RMS with dual antennas on a 2 m baseline. Attitude accuracy is ≤0.01 deg, and north-finding accuracy is ≤0.05 × secant(latitude). Satellite-integrated single-point position accuracy is ≤1.5 m RMS, while DVL and odometer integration specify position accuracy as 1% and 0.3% of distance traveled, respectively. Satellite-integrated velocity accuracy is ≤0.05 m/s RMS; inertial navigation position accuracy is ≤1 nm/h CEP.
