Aviation Navigation TDL45C 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
Enables alignment capabilities for both stationary ground platforms with vibration interference and in-flight navigation systems.
Features adaptive alignment mode switching (self-alignment, moving-base alignment, transfer alignment) to meet mission-specific requirements.
Integrates multi-source navigation data through advanced sensor fusion technology, including satellite, celestial, barometric, radio aids, and visual odometry inputs.
Incorporates built-in health monitoring with real-time fault diagnostics and alert mechanisms.
