Product Description
Aviation Navigation TDF46A Airborne Optical Gyro Inertial Navigation
The TDF46A airborne optical gyro inertial navigation system employs fiber-optic gyroscopes (FOGs) and high-precision quartz accelerometers as core sensing elements. Operating under strapdown or modulated system architectures, it utilizes advanced navigation algorithms processed through embedded computing units to achieve real-time inertial parameter calculation at refresh rates exceeding 200Hz.
Multi-Sensor Fusion Capabilities
This system seamlessly integrates 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.
Application Fields
- Fixed-wing UAVs
- Rotary-wing UAVs
- Specialized airborne vehicles
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
- Multi-sensor fusion incorporating satellite, celestial, altimeter, radio, and visual navigation data
- Equipped with system fault detection and alarm functions
