  • Bayat, M.; Crasta, N.; Aguiar, A.P.; Pascoal, A.M. (IEEE Transactions on Control Systems Technology, vol.24(1); 2016; 122-139)
    This paper addresses the problem of range-based autonomous underwater vehicle (AUV) localization in the presence of unknown ocean currents. In the setup adopted, the AUV is equipped with an attitude and heading reference ...
  • Maurya, P.; Curado, T.F.; António, P. (Navigation, Guidance and Control of Underwater Vehicles, vol.3(1); 2015; 76-83)
    This paper describes work done towards the development of advanced geophysical-based navigation systems for autonomous underwater vehicles (AUVs). The specific problem that we tackle is that of combining terrain-aided ...
  • Chodnekar, Y.P.; Mandal, S.; Rao, K.B. (International Journal of Research in Engineering and Technology, vol.4(5); 2015; 211-218)
    Ever increasing population of India demands high production of electrical energy which puts immense pressure on our limited stock of non-renewable sources of energy and makes us dependent over imports from foreign countries. ...
  • Afzulpurkar, S.; Maurya, P.; Navelkar, G.S.; Desa, E.S.; Mascarenhas, A.A.M.Q.; Dabholkar, N.A.; Madhan, R.; Prabhudesai, S.P. (Proceedings of the International Symposium on Underwater Technology (UT-2015), 23-25 February 2015. ; National Institute of Ocean Technology, Chennai; India; 2015; UT15-202)
    Autonomous underwater vehicles (AUV) traverse considerable distances underwater without any intervention. Very often the operations are in coastal waters with small depth, large horizontal distances, seabed obstacles, ...
  • Maurya, P.K.; Pascoal, A.; Gaur, A. (Recent Researches on Indus Civilization & Maritime Archaeology in India. ed by: Gaur, A.S.; Sundaresh,; Agam Kala Prakashan.New Delhi; 2015; 226-229)
    This article explains how underwater robots have the potential to become companions (buddies) to divers, effectively assisting them by carrying tools and instrumentation and taking high resolution images under the commands ...
  • Chakraborty, B.; Menezes, A.A.A.; Dandapath, S.; Fernandes, W.A.; Karisiddaiah, S.M.; Haris, K.; Gokul, G.S. (IEEE Journal of Oceanic Engineering, vol.40(1); 3-14)
    In this paper, a seafloor characterization technique to unravel the number of data classes using multibeam echo-sounding backscatter data has been demonstrated. An application of self-organizing maps (SOMs) to backscatter ...
  • Hassani, V.; Sorensen, A.J.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems CAMS 2013, Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 203-208)
    This paper addresses a filtering problem that arises in the design of dynamic positioning systems for ships and offshore rigs subjected to the influence of sea waves. The dynamic model of the vessel captures explicitly the ...
  • David, M-S; Pascoal, A.M.; Joaquin, A. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems CAMS 2013, Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 233-238)
    The availability of reliable underwater positioning systems to localize one or more vehicles simultaneously based on information received on-board a support ship or an autonomous surface vessel is key to the operation of ...
  • Teixeira, F.C.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems CAMS 2013, Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 239-244)
    This paper proposes novel methods with the potential to improve the performance of navigation and tracking systems in underwater environments. The work relies on well-established methods of potential field inversion and ...
  • Glotzbach, T.; Moreno-Salinas, D.; Aranda, J.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems, Osaka, Japan, September 17-20. vol.9; 2013; 215-220)
    This paper addresses the problem of optimal sensor placement for acoustic range-based underwater target positioning. In particular, we focus on the experimental set-up whereby target positioning is ...
