An unmanned drone-hydrographer named "Kalan" has been developed on Sakhalin, which can be used for autonomous monitoring of water resources and hydrographic work.
The floating drone was developed in Korsakov by the pupils of the Technical Creativity Center "Technosphere" under the guidance of the director Alexander Pyrkov.
It can be useful for studying the geological structure of a site in water transitions, constructing depth maps of a body of water, sampling soil or water for chemical analysis, surveying underwater pipeline routes.
This is not just a toy, but a big project that we are creating together with the children. We hope that our "Kalan" will be in demand in the future by clients who carry out hydrographic work.

But, as the Telegram channel "Unpiloted" notes, there is also a second marine unmanned hydrograph in Russia with the same name.
It can work for up to 8 hours without recharging, swim up to 5 km away, and operate in autopilot mode up to 35 km from the operator. Various equipment can be attached to it: multibeam echosounder, sonar, circular hydrolocator or laser scanning system.
It was developed in 2022, and in 2023 it already worked during the expedition of the Northern Fleet and the Russian Geographical Society. The Moscow "Kalan" made a relief survey of the bottom in the Kola Bay. He was looking for airplanes of the "Boston" type, which crashed during the Great Patriotic War, and possible magnetic mines.
