    Increasingly within gas turbine engine control, there is competitive pressure to provide more and more sophisticated controls, while at the same time reducing costs. Considerable work has been performed at the Sheffield University Control and Systems Engineering Centre analysing current full-authority digital engine controller (FADEC) technology and assessing the potential exploitation of commerci...

    Summary form only given. The demand for long mission duration, associated reliability and availability requirements, operation in unstructured environments, real time operating requirements, and flexibility of use has led to increasing levels of autonomy in underwater vehicles. Aspects of multi-sensor data fusion for vehicle localisation and obstacle detection, together with developments in estima... View full abstract»

    The new generation electronic sector scanning sonars is now allowing practical use of temporal information for signal processing tasks such as object classification and motion estimation. This paper presents an approach to the segmentation, 2D motion estimation and subsequent tracking of multiple objects in sector scan sonar image sequences. Initially, frequency domain filtering is used to disting... View full abstract»

  • The core simulator engine: integrating AUV subsystems with simulations

    Publication Year: 1996, Page(s):3/1 - 3/4

    One means of reducing the overall development time of an autonomous underwater vehicle (AUV) is to develop the sub-systems in parallel with the specification and characterisation of the spine architecture. If the two are developed hand in hand, development risks will be reduced. At the early stages of development, many of the sub-systems will not be available and it is thus necessary to simulate t...

  • GPS and AUVs: a solution to the problem of signal interruption

    Publication Year: 1996, Page(s):7/1 - 7/7

    Autosub, an AUV, called surfaces periodically to communicate with its base and to determine its position. The satellite-based Global Positioning System (GPS) has been chosen as the prime candidate for this latter requirement because of its near-instantaneous global coverage, and because of the challenges inherent in adopting a leading-edge technology as a principal component in the overall design....

  • Underwater acoustic telemetry for AUVs

    Publication Year: 1996, Page(s):4/1 - 4/4

    The paper deals with the development of acoustic telemetry links for autonomous underwater vehicles (AUVs) for which there are two principle communication requirements: a high data rate “up-link” from the AUV to the surface for retrieving sensor data such as video and sonar images; and a substantially lower data rate, but very reliable, bi-directional link for communicating command and...

    Navigation of underwater vehicles is a very demanding task, especially in confined environments. The risk of damage, expense and sometimes danger of recovering a vehicle makes improving the system's awareness of its environment a research priority. We propose here a novel approach for underwater navigation systems that combines data fusion from a variety of conventional on-board sensors (such as h... View full abstract»

    This paper presents a review of the work that is being carried out at the University of Southampton to develop electric thrusters for unmanned underwater vehicles. The work has concentrated mainly on electric thrusters for tethered work-class remotely operated vehicles, which work at fairly low vehicle speeds, as a replacement for existing hydraulic thrusters. It is also relevant to untethered aut... View full abstract»
