In today's ocean and inland navigation, the role of unmanned ships is becoming more and more prominent. It integrates intelligent control, remote communication, underwater detection, water surface troubleshooting and other functions in one of its complex and high-risk working environments. The advantages are becoming more and more obvious. The core part of the surface unmanned ship is its autonomous navigation control system, and its performance advantage directly affects the working effect of the unmanned ship. In the control system, the advantages of the positioning and attitude sensors are extremely obvious. More and more homogenized products, and with the improvement of various performances, mainly the rise of high-precision navigation drones, the application of this drone to the inertial navigation in the industry has also emerged. Since the unmanned ship opened the civilian market, there have been some marine equipment or related ship-type units that have been invested in this industry. When the unmanned ship using low-precision compass was used in the industry and the special needs of Party A were improved, The application of the guide has gradually developed a certain trend.
The unmanned ship is equipped with satellite positioning systems, attitude sensors, cameras, water depth gauges, temperature and salinity sensors, and other equipment. The satellite positioning system GPS/Beidou can determine the position of the unmanned ship and track it in real time. The attitude sensor is also called the inertial navigation device, which can measure the heading, roll and pitch of the hull autonomously; the camera obtains the underwater water in real time. The video information is transmitted to the monitoring point through the communication device to ensure navigation safety; the water depth measuring instrument can obtain high-precision underwater terrain; the temperature and salinity sensor can measure the surface temperature and salinity by recording and storing, and can obtain high precision. Hydrological data.
