EDUSAT had a multiple spot beam antenna with 1.2m reflector to direct precisely the Ku band spot beams towards their intended regions of India, a dual core bent heat pipe for thermal control, high efficiency multi-junction solar cells and an improved thruster configuration for optimized propellant use for orbit and orientation maintenance. The satellite used radiatively cooled Ku band Travelling Wave Tube Amplifiers (TWTAs) and dielectrically loaded C-band DE-Multiplexer for its communication payloads.

Missile Man of India, Dr.APJ Abdul Kalam inaugurated India’s first Broadband network on EDUSAT for School Students on 28 July 2005 in Thiruvananthapuram. And Kerala demonstrated how this Satellite could Successfully used to empower Teachers. In this way EDUSAT provided connectivity to schools, colleges and higher levels of education and also supported non-formal education including development communication.
