Widely Scalable Mobile Underwater Sonar Technology (WiMUST)

project WiMUST geophysical exploration

Sines'18 WiMUST sea trial

The Sines'18 sea trial took place from 21-28 January, inside and outside the port of Sines on the west coast of Portugal, involving ASVs and UAVs from ISME, GraalTech and IST with the main objective of testing existing and develop new state of the art underwater robotic technology for efficient geo-physical exploration of surficial sediment properties.
