#1

ISRO is all set to launch the “Pratham” satellite which was designed and built by students of IIT-Bombay. It is among the eight satellites including its weather satellite slated to launch on Monday, an official said. Conceptualized in 2008 with the aim of making IIT-B a centre for space science and technology research, the satellite weighs just 10 kg, is designed to fit within a cube of 30cms, and has a life span of around four months. The project will also kick start a collaboration between IIT-B and other Indian universities keen to contribute in India’s space sector and to share knowledge and facilities. This has led to completion of ground-stations for tracking the satellite in several colleges.

“The objective of Pratham is to empower the students involved with the skill set required to develop a satellite through various stages of design, analysis, fabrication and testing,” said the official. IIT-B has collaborated with some international universities like UCL, London and IPGP, Paris for the project. Pratham will transmit data when it passes over India and any university with a small ground station can detect its signals and measure the total electron counts (TEC) above the ground station as part of the education process to spread awareness among the students.

The student-designed satellite’s mission is four-fold: acquiring knowledge in the field of satellite and space technology, to fully design it by the students of IIT-B, launch it and measure TEC of ionosphere above India and Paris, and involve students from other universities in the satellite project, said the official. Pratham’s payload instrument comprises two monopole antennae transmitting at 145.98MHz and 437.45MHz. Measuring 30.5 cm by 33.4cm by 46.6 cm, it weighs 10.12 kg, is made of aluminum alloy and other space-grade materials, and has an on board computer. It has three monopoles, GPS, magnetometer, sun sensors, magnetorquers and is powered by Li-ion battery and four solar panels.

The satellite will be positioned in a sun-synchronous orbit around 670 km away and will pass over India around 11.30AM. For the project, entirely funded by the IIT-B, the ISRO has provided lot of technical help in terms of testing and guidance and the integration of the flight model of Pratham for which tests have been carried out in ISAC, Bangalore and SHAR, Sriharikota. Each year in September, a rigorous selection test was conducted for all IIT-B students from which they were inducted into the Pratham team and formalized after ascertaining their satisfactory work. The current strength of the team which has completed the project after more than eight years is around 30, the official said.
