Born on 20 April 1947 in Rajasthan, Prem Shanker Goel graduated in Engineering from the University of Jodhpur, secured a post graduate degree in Applied Electronics and Servomechanism from the Indian Institute of Science, Bangalore and continued at Bengaluru to complete his PhD from the Bangalore University. He started his career by joining the Indian Space Research Organization at their centre in Thiruvananthapuram in the project for Satellite Attitude Control System for spinning RS-1 satellite but later shifted to the Bengaluru centre to join the Aryabhata team. Over the years, Goel has served as the chairman of the Spacecraft System Advisory Board for IRS-1, the project engineer of the Attitude and Orbitalal Control Subsystem of the Ariane Passenger Payload Experiment, associate project director of INSAT-2, head of the control system, group director of Attitude and Orbitalal Control Subsystem, deputy director of Mission and Control Area, associate director and later, the director of ISRO satellite system. On his retirement from ISRO in 2005, he was appointed as the Secretary of the Department of Ocean Development, a post he held till 2008. During his tenure there, the department was developed into a full-fledged ministry, Ministry of Earth Sciences, by combining the departments of ocean, atmosphere, geoscience and atmosphere. The next move was as the Chairman of Recruitment and Assessment Centre of the Defence Research and Development Organisation. He is the incumbent Honorary Distinguished Professor at ISRO and holds the Professor M. G. K. Menon DRDO Chair. Goel is credited with the development of the spin axis orientation system for Bhaskara I and Bhaskara II satellites and the magnetic control for spinning satellites. His contributions are also reported in the Ariane Passenger Payload Experiment project in the development of momentum based III-axis control system, in the IRS-V project in the development of zero momentum biased III-axis control system and in the INSAT-II project in the development of configuration momentum biased attitude control system. He has also been involved in the development of TES, SRE missions and other communication and scientific missions. The first chairman of the Earth Commission, a global forum of scientists. and a member of several professional organizations such as the International Academy of Astronautics, Paris and the Indian National Academy of Engineering, Goel has over 100 scientific papers to his credit, published in peer reviewed national and international journals.
