海中観測実装工学研究センター発表のポイント：
◆ 従来、船舶の活用
- 海中・海底観測機器を現地まで運び、
- 機器と情報を通信する海面基地として、
- これまで船舶が活用されてきた。
しかし、コストが大きく機動性が低いという課題があった。
◆今回、ドローンの活用
ドローンによる観測機器支援を行った。
- 船舶に比べ、コストと時間が大幅に低減し、
- 海面の位置決定の精度も高く、
- 海中音響ノイズも低減することが判明した。
海中・海底AUVと通信：
本研究では、AUVなど海中・海底観測機器との通信や、
母船としての作業試験を行いました。
UAV同士の通信：
海面基地型UAV同士を沿岸域で通信させ、
200mの通信が実現されていることを、確認しました。
- その機体を保持する精度や、
- 海中音響ノイズの少なさの面でも、
- 船舶による機器運用よりも、優れていることが判明。

Remote Sensing | Free Full-Text | Underwater Communication Using UAVs to Realize High-Speed AUV Deployment
Abstract
To monitor ocean and seafloor properties in detail, sensors are generally installed on autonomous underwater vehicles (AUVs).
An AUV cannot accurately determine its absolute position and needs to communicate with a sea-surface vehicle.
However, sea-surface vehicles
cannot perform high-speed observations with high efficiency due to their low mobility and high labor and equipment costs, e.g., vessel charter charges, operator restraint time on the sea surface during observations, etc.
From this perspective,
unmanned aerial vehicles (UAVs) have potential as the next-generation communication platform.In this study,
we conducted a demonstration experiment to use UAV as a sea-surface base for underwater communication with an AUV.We investigated the capability of a UAV to land on the sea surface,
drift like a buoy to receive underwater data, and finally lift off to return to its base.
The experimental results suggest that
UAVs provide suitable communication performance for research near the shore in terms of robust hovering control, stability against sway, and operation speed.
To carry out more complicated work (such as transportation) of UAVs, further research in areas such as weight reduction is required.

Can communication-linked UAVs become AUVs’ BFFs?
Researchers in Japan are testing
whether the deployment of autonomous underwater vehicles (AUV) for research
can be significantly enhanced by pairing them with communication-linked UAVs hovering overhead to relay data to human monitors on the ground.
The recent tests determined that
UAVs hovering above the submarines provide similar communications capacities as surface-floating vessels, but with far greater speed, stability, and agility capacities.
Our results suggest that
because of their robust hovering control, stability against sea-surface sway, and operation speed,
UAVs may be a suitable communication platform with AUVs in ocean surveys
up to a distance of approximately one kilometer from the shore
