Pratham Satellite

ABOUT PRATHAM SATELLITE:

     The IIT Bombay Student Satellite Project is a landmark project taken up by IIT Bombay Students. The Objective of this project is to make IIT Bombay a respected centre for advancement in satellite and space technology that is being developed in the institute and also a method for space qualification.

Pratham is the first satellite under this project. The plan was to build a fully functional microsatellite which would then be launched by the Indian Space Research Organisation (ISRO). This is entirely a student initiative with mentorship provided by ISRO scientists and IIT Bombay Faculty.  The satellite will fit in a 30.5cmx33.5cmx46.6cmx46.6cm cube and will weigh 10.15kg excluding FE Ring.

    For the revelance of our satellite to the student community, we will be transmitting satellite data when the satellite passes over India so that any interested university with a small ground station will not only be able to detect the beacon signal fromour satellite but will also be able to measure TEC above their ground station. This is proposed to spread awareness among the student community about this exciting field. The Pratham Project presents a wonderful learning experience to the students of working on a real life multi-disciplinary complex system. A lot of importance is attached to learning, this is evident from the success criterion.
