Overview
The T75 high-precision fiber optic strapdown inertial navigation system uses a 75-type three-axis fiber optic gyroscope and a high-precision quartz flexural accelerometer as its core inertial devices to achieve high-precision measurement of carrier motion. It can be combined with a satellite positioning system (GNSS) or DVL and odometer to form a combined navigation system, and can transmit real-time navigation information such as speed, position and attitude to the outside world through the communication port at a specified period.

Features
● Small in size, light in weight, and high in precision.
● Flexible navigation modes: Supports multiple modes such as pure inertial navigation, GPS combined navigation, odometer combined navigation, and DVL underwater combined navigation to adapt to different application scenarios.
● Communication protocol is configurable: The communication protocol and baud rate can be set according to user needs.
● Excellent environmental adaptability; can be connected to external vibration damping brackets; resistant to strong impact vibration.
● Rich and reliable interface configuration: Equipped with digital communication interfaces such as RS422 and RS232 to meet the data interaction needs of multiple devices.
● High reliability.
