Land Force Navigation TDL45C Vehicle Mounted Optical Gyro Positioning And Orientation Equipment
The TDL45C vehicle-mounted optical gyro positioning and orientation equipment utilizes advanced laser or fiber optic gyros and quartz accelerometers as core sensors. Employing a strapdown inertial navigation system architecture with sophisticated navigation software, it delivers real-time navigation data across multiple operating modes including zero-velocity update (ZUPT), inertial/satellite-based integrated navigation, and inertial/odometer integrated navigation.
Application Fields
This optical gyro positioning system is compatible with diverse 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 serves positioning needs across civilian, and industrial applications.
Performance Characteristics
- Autonomous navigation with zero-velocity update (ZUPT) capability
- Integrated navigation with odometer and satellite-based systems
- Alignment and initialization in both static and dynamic (in-motion) states
- Suitable for high-latitude (±65°), extremely cold, and high-altitude regions
- High reliability design for demanding environments
