While autonomous underwater vehicles (AUVs) are generally used for scientific studies, they can also be used in areas such as surveillance and reconnaissance.
The companies that collect your data the most have emerged
Although some AUVs can travel deep underwater for days at a time, they must rise to the surface when it comes time to transmit the collected data to their users, as radio waves do not propagate well in water.
Autonomous underwater vehicles may not need to surface, thanks to the newly developed micro-AUV
The micro-AUV was developed by Cellula and ecoSUB, by Australian defense company Trusted Autonomous Systems. The developed micro-AUV is based on the hydrogen fuel cell Solus-LR AUV. Thanks to the micro-AUV, the Solus-LR was able to transmit data without surfacing.
The micro-AUV can independently move underwater up to several kilometers from the Solus-LR before resurfacing. Even if the micro-AUV is visible, which is unlikely to be noticed because it is much smaller than its main vehicle, its surface location does not reveal Solus-LR’s current underwater location. It also sinks to the seafloor after transmitting.
Thanks to this micro-AUV, autonomous underwater vehicles will now be able to transmit data without surfacing and the vehicle’s location will not be revealed. Due to the underwater vehicle’s location not being revealed, this technology could be used in future covert missions.
