Research Involves

Analysis, dynamics, and control of miniature satellites including pico-satellites (0.1-1 kg) and femto-satellites (<0.1 kg).

Research Relevance

The findings of the research will lead to the development of the required concepts and technological bases for the systems engineering and formation flying of miniature satellites.

Developing Miniature Satellites

The dynamics and control of miniature satellites based on micro-electro-mechanical systems, nano-technologies, intelligent and autonomous systems, and formation flying concepts represent a challenging and leading-edge research theme for future low-cost space missions. Dr. Kumar will undertake this highly ambitious research leading to the development of the required technologies for miniature satellites.

Dr. Kumar’s research focuses on satellite orbital manoeuvring, satellite formation flying, and satellite attitude stabilization ie control for optimal antenna direction and manoeuvre ie changing the orientation of the satellite.

He has made significant contributions in each of these areas including dynamics and control of tethered satellite systems ie two satellites connected by wire, and the application of non-equatorial geosynchronous orbits for satellite communications.

As Canada Research Chair in Space Systems Engineering, Dr. Kumar will address three primary research objectives: defining the engineering domain of pico- (0.1-1 kg) and femto satellites (<0.1 kg) ; improving mission analysis and design methodologies; and the techniques for miniaturizing hardware. The research will strongly contribute to systems engineering and formation flying research in Canada and help pave the way for innovative Canadian and international pico- and femto-satellite missions. One can expect potential spin-off benefits from this research program as it relates to hardware miniaturization and control software to other high-technology sectors in Canada.
