Aviation Navigation TDF41A Airborne Optical Gyro-Inertial Navigation
1 Introduction
The airborne optical gyro inertial navigation system (INS) utilizes optical gyros and quartz accelerometers as its core sensors, employing either a strapdown or dithered (modulated) inertial navigation system architecture. It runs advanced navigation software internally at high speed to provide real-time navigation information. This series of products can integrate satellite, celestial, altimeter, radio, and visual navigation information, based on user requirements. It supports multiple operating modes, including purely inertial and multi-sensor fusion, providing users with complete navigation parameters for their platforms.
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.
