Land Force Navigation TDL45C Vehicle-mounted Optical Gyro Positioning And Orientation Equipment
1 Introduction
The vehicle-mounted optical gyro positioning and orientation device uses laser or fiber optic gyros and quartz accelerometers as core sensors. It employs a strapdown inertial navigation system architecture and runs advanced navigation software to provide real-time navigation information. The product series features multiple operating modes, including zero-velocity update (ZUPT), inertial/satellite-based integrated navigation, and inertial/odometer integrated navigation. It provides users with complete navigation parameters for the vehicle, meeting the needs of various vehicle-mounted platforms.
2 Application field
The optical gyro positioning system is compatible with various vehicle platforms including geodetic survey vehicles, armored combat platforms (tanks, self-propelled artillery, infantry fighting vehicles), unmanned ground vehicles (UGVs), high-speed rail systems, agricultural machinery, and other mechanized platforms requiring precision navigation. This versatile solution meets the positioning needs across civilian, military, and industrial applications.
3 Performance characteristics
Features autonomous navigation, zero-velocity update (ZUPT), and integrated navigation with odometer and/or satellite-based systems.
Capable of alignment and initialization in static or dynamic (in-motion) states.
Suitable for use in high-latitude (±65°), extremely cold, and high-altitude regions.
High reliability.
