Land Force Navigation TDL46A Optical Gyro Positioning Orientation Equipment Vehicle Mounted

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.
