Aviation Navigation TDF46A Airborne Optical Gyro Inertial Navigation
1 Introduction
The airborne optical gyro inertial navigation system employs fiber-optic gyroscopes (FOGs) and high-precision quartz accelerometers as its core sensing elements, operating under either strapdown or modulated system architectures. Utilizing advanced navigation algorithms processed through embedded computing units, it achieves real-time inertial parameter calculation at refresh rates exceeding 200Hz.This system features multi-domain sensor fusion capabilities, seamlessly integrating satellite navigation (GNSS), celestial positioning, barometric altimetry, radio navigation, and visual odometry inputs through adaptive Kalman filtering techniques. Operational modes can be dynamically configured between pure inertial navigation and hybrid augmentation states, delivering comprehensive platform navigation solutions including 3D position, velocity, attitude, and heading parameters.
2 Application Fields
Suitable for fixed-wing UAVs, rotary-wing UAVs, and specialized airborne vehicles.
3 Performance Characteristics
Capable of alignment on ground-based vibrating platforms and in-flight alignment.
Supports switching between self-alignment, moving-base alignment, and transfer alignment based on customer needs.
Supports multi-sensor fusion, incorporating satellite, celestial, altimeter, radio, and visual navigation data.
Equipped with system fault detection and alarm functions.
