After the successful launch of Pratham, Advitiy was the second satellite under the Student Satellite Programme of IIT Bombay. The name Advitiy means 'Unparalleled' or 'Unprecedented'. The aim was to make it a robust, reliable and repeatable satellite bus. Advitiy would be transmitting pre-loaded and uplinked images through Slow Scan Television (SSTV) protocol which can be intercepted by a low-cost receiver (~5000 INR) that can be built even by a layperson. Thus, along with robustness and reliability, increasing space awareness and enthusiasm among India's youth and school children was another aim of Advitiy. After the announcement of opportunity for ISRO's PSLV Stage 4 Orbital Platform, the team decided to pause work on Advitiy and carry forward the work on Antenna Deployment System along with other suitable CubeSat subsystems whose indigenous development will be of relevance.
