Vietnam develops mini-unmanned ships
A research team of the Institute of Geodesy and Cartography (under the Ministry of Natural Resources and Environment) has successfully designed and built unmanned mini ships to survey, draw seabed maps and collect data on resources and environment. This is the result of a scientific project implemented within 30 months, from January 2018 to June 2020.


The project aims to set up a reverberation system with unmanned mini ships: Software and systems that integrate reverberation devices with inertial navigation devices IMU - GNSS - RTK - RTK on unmanned ships (USV). On that basis, the experts proposed a technological process to create a large topographic map of the rivers and the seabed.

Mr. Luu Hai Au - Director of the Center for Informatics and Geodetic Maps (belonging to the Institute of Geodesy and Cartography) said that the research team designed and built the systems that Vietnam had not previously had and had to imported from foreign countries.

After successful research and production, self-operated ships can measure data from a depth of 1 to 1,000 meters and automatically send data via radio signals and GPRS waves.

The ship is self-operated. The hull is made of a mixed plastic and installs data recording software, online cameras, satellite navigation devices, antennas and audio reverberation devices.

A small computer like a phone is also installed inside the ship to store data and send information to the system via radio and GPRS signals. Both hardware and software were developed by the research team.

The vessel has a payload of 60 kg and is equipped with two power batteries, so it can operate 8-10 hours in unsafe or polluted marine areas. Ships can also function as submarines to check and measure data to detect unauthorized discharge of sewage into the sea.
