Description

Aviation Navigation TDF71A Airborne Optical Gyro Inertial Navigation


1 Introduction

The airborne optical gyro inertial navigation system (INS) employs optical gyroscopes and quartz accelerometers as its core sensing components, utilizing either a strapdown‌ or modulated (dithered) system architecture‌. With high-speed embedded navigation algorithms‌, it delivers real-time positioning and orientation data. This product series integrates satellite-based (GNSS), celestial, barometric altimeter, radio navigation, and visual perception inputs through configurable fusion architectures‌, tailored to mission-specific requirements. Supporting diverse operational modes ranging from standalone inertial navigation‌ to hybrid multi-sensor solutions‌, it provides comprehensive platform navigation parameters including 3D position, velocity, attitude, and angular rates‌.


2 Application Fields

Suitable for fixed-wing UAVs, rotary-wing UAVs, and specialized airborne vehicles.


3 Performance Characteristics

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.

Capable of alignment on ground-based vibrating platforms and in-flight alignment.

Equipped with system fault detection and alarm functions.
