Large-sized UUV INS

TYLXXC is an autonomous positioning highest accuracy inertial guide equipment equipped with unmanned submarines. It overcomes the problem of laser gyroscope jitter noise. The underwater radiation noise is extremely low, close to the underwater background noise. This model has been applied to multiple platforms of Chinese ships.

What is INS in GNSS?

An Inertial Navigation System (INS) is a system that is used to compute relative position over time from rotation and acceleration information provided by an Inertial Measurement Unit (IMU). An INS uses the measurements from the IMU to provide position, velocity and attitude (roll, pitch and azimuth) calculations.

Inertial Navigation System (INS) provides reliable position and orientation data even in the absence of GPS signals. Maritime Navigation: Ships and submarines use INS for navigation and control, particularly when operating underwater or in environments where GPS signals are unavailable.

An INS often receives data from a global navigation satellite system (GNSS) receiver and fuses it with data from the IMU to provide information to the host computer about the platform's absolute position (latitude, longitude, and altitude) and attitude (roll, pitch, and heading).
