Indian Space Organization has made tremendous development satellite launch vehicles and services and attained the capability of designing and executing satellite missions of high complexity and capability in all the areas of remote sensing, communication and space exploration. As the global technology advances have been progressing for the past three decades in the development of miniaturized devices and systems with high capability the satellites also could be designed with low mass and volume. This small satellites have been initially designed and used for educational and experimental purposes leading to related technology developments all over the globe.
Commensurate with global changes small satellites design and development was initiated in India for experimental, operational and educational purpose, the small satellites are generally categorized as follow:
Less than 1000kg in general are called small satellites
1000kg - 500kg are small satellites
500kg - 100kg are mini satellites
100kg - kg10 are micro satellites
10kg – 1kg are nano satellites
1kg –, 100grams are pico satellites
100grams – 10grams are femco satellites
India also has developed small satellites versions, in mini and micro categories and proven the missions. The small satellites in the category of Nano and Pico where also made by the Institutions for educational purposes under the guidance of ISRO. As the miniaturization technology is maturing globally the small satellites upto the nano category are entering into experimental and operational missions and with the increase of demands for satellite applications, with higher temporal frequency the requirement of number of satellites is increasing and missions with constellation of satellites are becoming feasible as well as necessary options for the space infrastructure. With this growth, it has became necessary to increase the capacity in the areas of designing development and production of small satellites, with qualified manpower in this area. For this, capacity building has to be done, in all the areas of research, academia and industries as an enabling effect. Also for capacity building it was necessary to bring all the stake holders on to a single forum and thus the Society for Small Satellite Systems (SSSS) was established on 15th February 2017.It was a historic day for India on which a record 104 satellites were launched by PSLV ,SSSS was established with around 22 founder members and it is growing significantly with experts in satellite technology mission ground segment applications of satellite technology area and academicians from educational institutions and industrial executives.
