Land Force Navigation TDF71A 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 core sensing components. Operating under a strapdown inertial navigation system architecture, it employs advanced algorithmic software to deliver real-time navigation data. This product series supports multiple operational configurations including Zero-Velocity Update (ZUPT), inertial/satellite integrated navigation, and inertial/odometer fusion navigation, providing comprehensive vehicle motion parameters for diverse mobile platform requirements.
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.
