Product Description
Aviation Navigation TDF41A Airborne Optical Gyro Inertial Navigation
Product Overview
The TDF41A airborne optical gyro inertial navigation system utilizes optical gyros and quartz accelerometers as core sensors, employing either strapdown or dithered inertial navigation architecture. With advanced high-speed navigation software, it delivers real-time navigation data and supports integration with satellite, celestial, altimeter, radio, and visual navigation systems based on user requirements.
Application Fields
Suitable for fixed-wing UAVs, rotary-wing UAVs, and 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 capability with satellite, celestial, altimeter, radio, and visual navigation data
- Integrated system fault detection and alarm functions
