Systems research for unmanned autonomous underwater vehicles

Unmanned autonomous underwater vehicles (AUVs) hold considerable promise as a major new tool for gathering data in the deep ocean. However, developments are needed in a range of key technologies before reliable and cost-effective deep-diving vehicles (6000 metres depth) can be fully realised. The paper describes progress being made in a European collaborative research project (supported under Alliance and EC MAST II programmes) in three generic areas fundamental to AUV design: the application of carbon fibre composites in pressure hull design, sub-surface navigation, and the implications of sensor payload for vehicle design and control. Initial analysis of some representative science missions is helping to guide the work
