ABSTRACT
 CubeSats, miniature satellites, are playing an increasingly larger role in space exploration, technology demonstrations, scientific research and educational investigations. These miniature satellites provide a low-cost platform for various missions, including planetary space exploration; Earth observation; fundamental Earth and space science; and technology demonstrations such as cutting-edge laser communications, energy storage, in-space propulsion and autonomous movement capabilities. They also allow educators an inexpensive means to engage students in all phases of satellite development, operation and exploitation through real-world, hands-on research and development experience. There has been a rising emergence of researchers, universities and professional institutions constituting towards the development and launching of these CubeSats. CubeSat is a generic term for a miniature satellite which is designed using commercial offthe-shelf components for development of its electronics framework [1] which capcitates anyone to build a satellite. A CubeSat has a volume of 1 liter, which translates into a cube having a 10 cm edge. A typical CubeSat weighs approximately 1 kilogram. The most remarkable feature of such satellites is the simplified development cycle; the use of off-the-shelf hardware and easy access to software resources has led to rapid rise in the number of the CubeSats deployed. They provide an economic approach for academia to contribute towards space research. CubeSats are highly modular and can be used to form larger satellites. The electrical system of a CubeSat is driven by the EPS, the powerhouse of the CubeSat. It is responsible for powering the various components of the CubeSat which includes the control unit, servo mechanisms, scientific equipment and communication modules.
