    • An autonomous underwater vehicle "Maya", for monitoring coastal waters, estuaries, rivers and dams 

      Mascarenhas, A.A.M.Q.; Navelkar, G.S.; Madhan, R.; Dabholkar, N.A.; Prabhudesai, S.P.; Maurya, P.; Desa, E.; Afzulpurkar, S.; Suresh, T.; Matondkar, S.G.P.; Mahalunkar, A. (Indian National Centre for Ocean Information Services (INCOIS), 2012)
      This article demonstrates the use of Maya, Autonomous Underwater Vehicle (AUV) for monitoring coastal waters, estuaries, rivers and dams. Maya is a mono hull structure with detachable nose and tail cones. The nose cone is ...
    • Development of an autonomous vertical profiler for oceanographic studies 

      Dabholkar, N.; Desa, E.; Afzulpurkar, S.; Madhan, R.; Mascarenhas, A.A.M.Q.; Navelkar, G.S.; Maurya, P.; Prabhudesai, S.P.; Nagvekar, S.; Martins, H.; Sawkar, G.; Fernandes, P.; Manoj, K.K. (Allied, 2007)
      The variations in oceanic variables that influence global climate, hypoxia in freshwater reservoirs and in coastal waters as in the west coast of India, the rise of harmful algal blooms are amongst current problems that ...
    • Field evaluation of navigational sensors using DGPS/GPS for a small AUV 

      Mehra, P.; Desai, R.G.P.; Mascarenhas, A.A.M.Q.; Sukerkar, A.; Desa, E.S.; Navelkar, G.S.; Madhan, R.; Desa, E.; Prabhudesai, S.P.; Afzulpurkar, S.; Chakraborty, B.; Maurya, P. (Allied, India, 2003)
      This paper presents the preliminary results of a field experiment for low-cost strap down IMU/GPS combination for the estimation of 2-D components of vehicle position (Trajectory). In present approach the effects of earth ...
    • Four-quadrant propeller modeling: A low-order harmonic approximation 

      Haeusler, A.J.; Saccon, A.; Hauser, J.; Pascoal, A.M.; Aguiar, A.P. (International Federation of Automatic Control, 2013)
      We propose a four-quadrant propeller model suitable for energy-efficient motion planning of autonomous marine vehicles. The model can be used to capturethe main features of experimental thrust and torque curves by using a ...
    • Investigation of a method for predicting AUV derivatives 

      Barros, E.A. de; Pascoal, A.; Desa, E.S. (Elsevier, 2008)
      The paper addresses the problem of autonomous underwater vehicle (AUV) modelling and parameter estimation as a means to predict the dynamic performance of underwater vehicles and thus provide solid guidelines during their ...
    • Miniature sonar for obstacle detection on samll AUV Maya 

      Afzulpurkar, S.; Desa, E.; Navelkar, G.S.; Mascarenhas, A.A.M.Q.; Maurya, P.; Martins, H.; Madhan, R.; Prabhudesai, S.P.; Pinto, R.; Marchon, N. (Allied, 2007)
      Autonomous platforms are increasingly able to collect in-situ data with least disturbance to the parameters under measurements. To attain high level of autonomy they need to posses capabilities to detect and avoid obstacles ...
    • Safety aspects for underwater vehicles 

      Madhan, R.; Navelkar, G.S.; Desa, E.S.; Afzulpurkar, S.; Prabhudesai, S.P.; Dabholkar, N.; Mascarenhas, A.A.M.Q.; Maurya, P. (Springer, 2010)
