Land Force Navigation TDL85A Vehicle Mounted Optical Gyro Positioning Orientation Equipment

Land Force Navigation TDL85A Vehicle-mounted Optical Gyro Positioning And Orientation Equipment

1 Introduction

This vehicle-mounted optical gyro positioning and orientation system utilizes laser or fiber optic gyroscopes combined with quartz accelerometers as its core sensors. Employing a strapdown inertial navigation system (SINS) architecture with advanced navigation software, it delivers real-time navigation data through multiple operational modes. These include Zero-Velocity Update (ZUPT) for stationary calibration, inertial/GNSS integrated navigation (e.g., GPS/BeiDou), and inertial/odometer integration. The system provides complete vehicle navigation parameters (position, velocity, attitude) to meet the diverse requirements of various vehicle 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.
