High Precision TDLG90S Ring Laser Gyroscope
1 Introduction
The ring laser gyroscope (RLG) operates on the Sagnac effect as its foundational principle, utilizing the interference phase difference between clockwise and counterclockwise laser beams within a closed resonant cavity to precisely measure angular increments of the carrier. This type of gyroscope demonstrates high integration level, exceptional reliability, strong environmental adaptability, and stable operational performance, making it a core sensor in high-precision inertial navigation systems widely adopted in both domestic and international applications.
2 Application
"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), and terrestrial navigation modules (automotive/military vehicles)."
3 Characteristics
Light path and circuit are encapsulated in one unit, simple structure and easy installation;
Small size, light weight, easy integration and controllable power consumption
High reliability, shock and vibration resistance, and strong environmental adaptability;
Wide dynamic response bandwidth, digital signal output.
