Unmanned Surface Vehicle Grethe

USV Grethe has multiple research purposes within the lab. The autonomous boat can serve as a relay between air and water communications. It is built out of tough plastic to account for rough behandling and weather. It is a platform for sensors, both over and under the surface. Its quite electric engine makes it highly efficient and it has been kept running trials exceeding 24hr. 

There are three moonpools in the vehicle that can suit a large variety of instruments. These devices can operate independently but they can also be cable to the boats power supply and to a computer on board. The user will find an A-frame in the aft were sensors can be placed having a direct look into the sky. 

The vehicle can be deployed with a crane and its launch and recovery system safely from a dock or a boat. Alternatively, you can release it with a trailer from a ramp.
