How To Navigate The Unmanned Submersible AUV
Dec 27, 2018

The AUV control system pre-plans the path and analyzes the actual trajectory of the AUV through the high-precision navigation and positioning sensor. Then, if you want to perform the task accurately under the water and keep the navigation stable, the high-precision navigation and positioning technology is an indispensable equipment. The current mainstream navigation methods are as follows:
1, GNSS navigation system
2. Dead reckoning navigation system
3. Acoustic navigation system
4.inertial navigation system
The inertial navigation system is a system that relies entirely on its own equipment for navigation. According to Newton's inertia principle, the inertial device (GYRO/ACC) is used to measure the linear acceleration and angular acceleration parameters of the object relative to the inertial space, and the integrated output is performed under the known initial conditions. Parameters such as attitude and position, this navigation method is not interfered by the external environment, and has the characteristics of good concealment. It is the main navigation method of underwater navigation. However, due to the error accumulation of the inertial device itself, generally, equipments with high precision requirements need other equipment to perform auxiliary correction and use together.
