Product Description
Aviation Navigation TDF71A Airborne Optical Gyro Inertial Navigation
The TDF71A airborne optical gyro inertial navigation system employs optical gyroscopes and quartz accelerometers as core sensing components, utilizing strapdown or modulated system architecture. With high-speed embedded navigation algorithms, it delivers real-time positioning and orientation data. This system integrates satellite-based (GNSS), celestial, barometric altimeter, radio navigation, and visual perception inputs through configurable fusion architectures tailored to mission requirements.
Application Fields
Suitable for fixed-wing UAVs, rotary-wing UAVs, and specialized airborne vehicles.
Performance Characteristics
- Supports switching between self-alignment, moving-base alignment, and transfer alignment
- Multi-sensor fusion incorporating satellite, celestial, altimeter, radio, and visual navigation data
- Capable of alignment on ground-based vibrating platforms and in-flight alignment
- Equipped with system fault detection and alarm functions
