With the improvement of intelligence, many manual operations on ships are gradually being replaced by systems. China Shipbuilding Industry Corporation announced that it will design and construct the first intelligent demonstration ship in China, i-DOLPHIN, with a load capacity of 38800 tons. The so-called intelligent ship refers to the use of sensors, communications, the Internet and other technical means to automatically perceive the ship's information and data, and realize the intelligent operation of the ship through automatic control technology and big data processing and analysis technology.

In recent years, China's maritime departments and related enterprises have begun to develop some small intelligent unmanned ships for civilian use. For example, since 2009, the unmanned ship research group of the First Institute of Oceanography of the State Oceanic Administration has been the first to carry out research and application of unmanned ship systems in China. At present, two unmanned ships have been developed and undertaken multiple national level unmanned ship related projects. The lake and sea trials conducted in the relevant waters of Lianyungang in 2014 mainly completed automatic control navigation such as speed, heading, GPS position, and path tracking. Generally speaking, the above-mentioned unmanned ships are compact, flexible, and easy to use. By equipping advanced equipment such as GPS satellite positioning system, water depth measurement instrument, camera, temperature sensor, salinity sensor, AHRS, attitude detector, etc., a significant amount of labor costs can be saved.

The AHRS series products developed by Huilian Technology can determine the position and heading of unmanned ships, track the heading and waypoint, and accurately achieve automatic control of heading and GPS position.
