High Accuracy Vertical Fiber Optic Gyro System for MEMS / GNSS Navigation
Navigation Fiber Optic Vertical Gyro system
Employing high accuracy FOG, Q-flex accelerometers, dual-frequency
GPS position & orientation system, barometric altimeter and
advanced integration navigation and attitude measurement algorithm,
the performance of Attitude and Azimuth Integrated Navigation Fiber Optic Vertical
Gyro has been dramatically improved. Combining built-in high accuracy
IMU (inertial measurement unit) with satellite, it could output
high accuracy position, speed, attitude, angular speed and
acceleration information. While the satellite signal is completely
covered, system would enter into pure inertial mode. By use of high
accuracy FOG, it could still keep good attitude measurement
accuracy in certain time. Integrated with barometric altimeter, it
could make correction and get higher accuracy height information.
Application
Aircraft flight control and navigation
Ship-borne & vehicle-borne navigation system
Inertial stability control system
E-traffic measurement system
Industrial & agricultural measurement and application
