BW-GI4400 is a high-performance and high-precision fiber-optic integrated navigation system developed by Bewis for aviation surveying and mapping, unmanned aerial vehicles, sea-based and road-based fields. Built-in three-axis fiber optic gyroscope, three-axis accelerometer, optional three-axis magnetic sensor, high-precision air pressure sensor, including a BD/GPS/GLONASS three-mode receiver. It can measure the speed, position, and attitude of the carrier, and output the compensated angular rate, acceleration, magnetic field, air pressure, temperature and other information.

BW-GI4400 is equipped with a brand-new integrated navigation sensor fusion algorithm engine, optimized for multi-path interference, which can well meet the needs of long-term, high-precision, and high-reliability navigation applications in urban and field complex environments. The product supports multiple external sensors such as GNSS/odometer/DVL/barometric altimeter, and has excellent scalability. By using multi-sensor data fusion technology to combine inertial measurement with satellite navigation, odometer information and other information, the system can be regional adaptability and robustness have been greatly improved.

The BW-GI4400 integrated navigation system uses tight coupling technology to closely combine high-precision, professional-grade, multi-channel, dual-antenna single-frequency carrier phase and pseudo-range GPS receivers with high-precision optical fiber inertial measurement units. It has small size, light weight, and Features such as high performance.
