Dr. Ranganath Navalgund obtained his Ph D in Physics from the Tata Institute of Fundamental Research, Mumbai and joined the Space Applications Centre (ISRO) in 1977. Since then he has worked in ISRO till today in different capacities. His scientific contributions are in the broad area of earth observation systems, science and applications. As Director of National Remote Sensing Centre (2001-2005) and the Space Applications Centre (2005-2012), the two major centres of ISRO, he has over seen the formulation and execution of national level  RS application programmes, establishment of EO data reception systems, Decision Support Centre for disaster monitoring and mitigation, development of electro-optical and microwave sensors for Indian earth observation and planetary science missions, communication and navigation payloads onboard Indian satellites and has interfaced with several space agencies of different countries in a leadership role. He was the President of the International Society for Photogrammetry and Remote Sensing Technical Commission VII (2000-2004). He is a Fellow of the Indian Academy of Sciences, an Academician of the International Academy of Astronautics and a fellow of many other professional societies. He has been a recipient of many awards including the Bhaskara award of the Indian Society of Remote Sensing and the Outstanding Achievement award of ISRO besides many others. He is also in the Editorial Board of Current Science, a professional Indian journal. He is currently Honorary Distinguished Professor at ISRO Headquarters, Bengaluru. Dr. A. Senthil Kumar received Ph.D. from the Indian Institute of Science, Bangalore in the field of image processing in 1990. He joined ISRO in 1991 and has been serving in Indian satellite programs in various capacities. His research includes sensor characterization, radiometric data processing, image restoration, data fusion, and soft computing. He is currently the Director of Indian Institute of Remote Sensing, Dehradun and also the Director of UN affiliated Center for Space Science and Technology Education in Asia and the Pacific. He is the President of ISPRS Technical Commission V on Education and Outreach, and also as Chair of CEOS Working Group on Capacity Building and Data Democracy.
