T75R

Fiber Optic Inertial Navigation

The T75R single-axis rotating fiber optic inertial navigation system uses a Type 75 three-axis fiber optic gyroscope and a high-precision silicon microaccelerometer as its core inertial components to achieve high-precision measurement of carrier motion. Error suppression is achieved through single-axis rotation modulation. It can form a combined navigation system with a satellite positioning system (GNSS) or DVL and odometer, and transmits real-time navigation information such as speed, position, and attitude to the outside world through the communication port at a specified period.

High Precision: Delivers superior navigation accuracy.
Versatile Navigation Modes: Supports Pure Inertial, GPS-aided, Odometer-aided, and DVL-aided underwater navigation for diverse scenarios.
Configurable Protocols: User-definable communication protocols and baud rates.
Robust Environmental Adaptability: Engineered to withstand high-impact shocks and severe vibrations.
Rich & Reliable Interfaces: Equipped with RS422, RS232, and other digital ports for seamless multi-device data exchange.
High Reliability: Ensures stable, long-term operation in critical applications.
