Product Description
High Precision TDLG90S Ring Laser Gyroscope
The TDLG90S Ring Laser Gyroscope operates on the Sagnac effect principle, utilizing interference phase differences between clockwise and counterclockwise laser beams within a closed resonant cavity to precisely measure angular increments. This gyroscope features high integration, exceptional reliability, strong environmental adaptability, and stable operational performance, making it a core sensor in high-precision inertial navigation systems.
Applications
Certified for integration with inertial navigation systems (INS) and attitude heading reference systems (AHRS) across:
- Aerospace platforms (spacecraft/aircraft/satellites)
- Marine systems (surface vessels/submersibles)
- Terrestrial navigation modules (automotive/military vehicles)
Key Characteristics
- Integrated light path and circuit design with simple structure for easy installation
- Compact size, lightweight construction, and controllable power consumption
- High reliability with excellent shock and vibration resistance
- Strong environmental adaptability and stable operational performance
- Wide dynamic response bandwidth with digital signal output
