Land Force Navigation TDL65A Vehicle-mounted Optical Gyro Positioning And Orientation Equipment
1 Introduction
The vehicle-mounted optical gyro positioning and orientation system utilizes laser/fiber optic gyros and quartz accelerometers as core sensors. Adopting a strapdown inertial navigation architecture with advanced navigation algorithms, it delivers real-time positioning data. This product series supports multiple operational modes: Zero Velocity Update (ZUPT), GNSS-aided inertial navigation, and odometer-assisted inertial navigation. Designed for diverse vehicular platforms, it provides comprehensive navigation parameters to meet various operational 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
Features autonomous navigation, zero-velocity update (ZUPT), and integrated navigation with odometer and/or satellite-based systems.
High reliability.
Suitable for use in high-latitude (±65°), extremely cold, and high-altitude regions.
Capable of alignment and initialization in static or dynamic (in-motion) states.
