Prof. Prof. Sheral Crescent Tissera
Bio(Dr. Sheral Crescent Tissera)
Dr. Sheral Crescent Tissera is an Assistant Professor in the Department of Electrical and Computer Engineering, College of Design and Engineering, National University of Singapore (NUS). Concurrently, he is also the Deputy Director of Satellite Technology and Research Centre (STAR). Before his present employment, he was a Research Engineer at Satellite Research Centre (SaRC), Nanyang Technological University (NTU), Singapore from Jul 2013 to Jan 2017.
Dr. Tissera received a B.Eng. degree in Aerospace Engineering and a M.Eng. degree in Electrical and Electronics Engineering from NTU in 2013 and 2017, respectively. In 2023, he earned a Ph.D. degree in Electrical and Computer Engineering from NUS, focusing on satellite attitude determination and control.
He has over a decade of experience in building eight satellites out of which four satellites: VELOX-I, VELOX-II, VELOX-C1, and LUMELITE-4 have been successfully launched into space. His research interests include spacecraft attitude determination and control, formation flying satellites, space robotics and mechanisms.
Abstract
Lumelite is a modular and scalable satellite platform designed by the Satellite Technology and Research Centre (STAR) of National University of Singapore (STAR@NUS). The research focus of STAR@NUS is on the study and development of distributed space systems whereby several small satellites will be flying together in formation or constellation to perform collaborative sensing. One such effort is the Formation Flying Satellite Program, the flagship program of STAR@NUS in collaboration with DSO National Laboratories. As part of this program, three satellites: Lumelite 1-3 will be launched onto a Low Earth Orbit in Q1 2024 to indigenously build up Singapore’s capability for the first time with multiple satellites flying in tight formation.
In this seminar, an overview of Lumelite 1-3 satellites and development philosophy will be presented. The satellites are equipped with propulsion systems to demonstrate formation flying and are controlled by the on-board attitude determination and control system (ADCS). The development of the Lumelite ADCS will be discussed in detail.
