Anwar Ali was born in 1981. He received his M.S. degree in Electronic Engineering and Ph.D. degree in Electronic and Communication Engineering fromPolitecnico di Torino, Italy in 2010 and 2014, respectively. During PhD, he worked on AraMiS (Italian acronym stands for modular architecture of small
satellites) project which is a joint venture between Politecnico di Torino, MIT (Boston, USA), Spin Electronics and NeOhm.
Since March 2019, he is working as Associate Professor at the School of Information Science and Technology, Zhejiang Sci-Tech University, Hangzhou,
China.He has published 35 research papers in renowned journals and conferences around the globe and has completed 5 research projects as Principle Investigator. His research interests include design and development of aerospace systems, power electronics, analog circuits and thermal analysis &
thermal modeling of aerospace systems.
Innovative Embedded Magnetorquer for the Attitude Control of a Small SpaceCraft
The nanosatellite market is rapidly growing for scientific and commercial applications. The main reason is the availability of low-cost commercial off-the-shelf components and already-developed subsystems in the market. This evolution also enabled many universities and small and medium-sized
enterprises (SMEs) to develop their own satellites. The problem with small satellites is the available space and weight constraints for housing a large
number of required subsystems, such as power, attitude determination and control, telecommunication, and payload. The ultimate solution is to make
all subsystems smaller and lighter. Attitude control system orientate the satellite in space to rotate solar panels towards Sun and antennas towards
ground station. Normally permanent magnets, reaction wheels, and magnetic rods are used for this purpose, but their price, weight, and size make
them incompatible with small satellites. In this conference, we are going to discuss an innovative embedded attitude actuator called embedded
magnetorquer coil, which is inserted in the internal layers of the power management PCB (printed circuit board) of a small satellite. The resultant
system is very light, reconfigurable and occupies no extra space on the spacecraft.
