For successful operation of the autonomous underwater vehicle many techniques have to be met. Computer structures both in the planning console and in the vehicle have to offer maximum flexibility, provide distributed intelligence and offer an object-oriented structure. Mission management systems perform vehicle guidance, assure intelligent behavior in special situations, provide a degradation mode for emergencies and/or plan missions independently with due consideration to the targets set. Mission-specific sensor systems support vehicle guidance, avoid collisions and perform the actual measuring tasks. The power supply has to deliver sufficient energy with maximum efficiency, while the system should be kept as small as possible. Optimized shaping and drive systems allow operation with minimized energy consumption. Additionally, control and maneuvering devices allow the desired movement properties. In the event of any defects, the system should be capable of diagnosing and eliminating these without external assistance. The development of the DeepC AUV system has set new standards in the technology for underwater vehicles, e.g. the use of carbon composites for a high-strength yet light-weight pressure hull - a solution that is unique for such applications - the use of a compact PEM fuel cell system with hydrogen and oxygen as an efficient power generation system, the application of a new type of electrical drive motors with adapted propulsion systems which can be used as pressure-neutral structures, the innovative power distribution and safety process on power-bus basis, the vehicle guidance system using CORBA (Common Object Request Broker Architecture) and distributed redundant processor nodes (distributed intelligence), the autonomous situation-adaptive vehicle guidance and control, the vehicle integrated autonomous operational monitoring/status control with derived fault strategy as well as the extremely precise underwater long-term navigation on the basis of stochastically drifting measurement values. The paper describes the current development status, deals with the applications and gives an outlook into the future.
