Overview
The T75R fiber optic inertial navigation system uses a 75-type three-axis fiber optic gyroscope as its core inertial device to achieve high-precision measurement of carrier motion. Error suppression is achieved through modulation. It can form a combined navigation system with a satellite positioning system (GNSS) or DVL and odometer, and transmit real-time navigation information such as speed, position and attitude to the outside world through the communication port at a specified period.
Features
● High 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 and resistance to strong impact and vibration.
● Rich and reliable interface configuration: Equipped with digital communication interfaces such as RS422 and RS232.
● It meets the data interaction needs of multiple devices.
● High reliability.
