Product Description
Aviation Navigation TDF61A Airborne Optical Gyro Inertial Navigation
The TDF61A airborne optical gyro inertial navigation system utilizes optical gyros and quartz accelerometers as core sensing components, operating under strapdown or dither-modulated navigation architecture. High-speed embedded software processes sensor data in real-time to deliver continuous positioning and orientation outputs. This system integrates multiple navigation sources including GNSS satellite signals, celestial observations, barometric altimetry, radio navigation aids, and visual odometry based on mission 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 incorporating satellite, celestial, altimeter, radio, and visual navigation data
- System fault detection and alarm functions
