Land Force Navigation TDL46A Vehicle-mounted Optical Gyro Positioning And Orientation Equipment
1 Introduction
The vehicle-mounted optical gyro positioning and orientation system utilizes laser or fiber optic gyroscopes combined with quartz accelerometers as its core inertial sensors. Operating on a strapdown inertial navigation system (SINS) architecture, it executes sophisticated navigation algorithms to deliver real-time positioning, orientation, and navigation data. This product line supports multiple operational modes, including Zero-Velocity Update (ZUPT), GNSS/INS integrated navigation, and odometer/INS integrated navigation. It provides comprehensive vehicle navigation parameters, catering to the requirements of diverse vehicular platform applications.
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
Suitable for use in high-latitude (±65°), extremely cold, and high-altitude regions.
Features autonomous navigation, zero-velocity update (ZUPT), and integrated navigation with odometer and/or satellite-based systems.
High reliability.
Capable of alignment and initialization in static or dynamic (in-motion) states.
