Land Force Navigation TDL645B Vehicle-mounted Optical Gyro Positioning And Orientation Equipment
1 Introduction
Incorporating laser or fiber optic gyros along with quartz accelerometers as core sensors, this vehicle-mounted optical gyro positioning and orientation system utilizes a strapdown inertial navigation architecture. It employs sophisticated navigation software to deliver real-time vehicle navigation parameters. The product series supports multiple operational modes: zero-velocity updates (ZUPT), integrated GNSS/IMU navigation, and integrated inertial/odometer navigation. This comprehensive system provides complete and continuous vehicle position, velocity, and attitude information, meeting the diverse requirements of various vehicle-mounted platforms.
2 Application field
Suitable for geodetic survey vehicles, tanks, self-propelled artillery, infantry fighting vehicles, unmanned vehicles, high-speed trains, agricultural machinery vehicles, etc.
3 Performance characteristics
Capable of alignment and initialization in static or dynamic (in-motion) states.
Features autonomous navigation, zero-velocity update (ZUPT), and integrated navigation with odometer and/or satellite-based systems.
Suitable for use in high-latitude (±65°), extremely cold, and high-altitude regions.
High reliability.
