Isro to Launch IIT-Bombay Students' Satellite 'Pratham' on Monday

September 25, 2016

Sep 25: Indian space agency Isro will shoot off the "Pratham" satellite designed and built by students of the IIT-Bombay among the eight satellites including its weather satellite on Monday, an official said in Mumbai.

Conceptualised in 2008 with the aim of making IIT-B a centre for space science and technology research, the satellite weighs just 10kg, is designed to fit within a cube of 30cm, and has a life span of around four months.

"The objective of Pratham is to empower the students involved with the skill set required to develop a statellite through various stages of design, analysis, fabrication and testing," said the official.

The project will also kickstart a collaboration between IIT-B and other Indian universities keen to contribute in the space sector and to share knowledge and facilties.

This has led to completion of ground-stations for tracking the satellite in several college, including the Atharva College of Engineering here.

The 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 uonosphere 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 30.5cm by 33.4cm by 46.6 cm, it weighs 10.12kg, is made of aluminium 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.

It 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.

New Delhi, Jun 18: Vodafone Idea on Thursday told the Supreme Court that it has incurred Rs 1 lakh crore losses as it insisted it is not in a position to furnish bank guarantees.

A bench comprising Justices Arun Mishra, S. Abdul Nazeer, and M.R. Shah, taking up the adjusted gross revenue (AGR) matter through video conferencing, directed the telecom companies to submit their financial documents and books for the last 10 years.

Asking Vodafone if it was a foreign company, the bench said that how can the company say it would not furnish any bank guarantee.

"What if you fly away overnight in future without paying anything?" it asked.

Senior advocate Mukul Rohatgi, representing Vodafone Idea, denied his client is a completely foreign firm and cited before the bench its tie-ups and investments.

Vodafone owes over Rs 58,000 crore as AGR dues and so far, has paid close to Rs 7,000 crore.

Rohatgi contended before the court that the telecom company is in a tough situation, and cannot furnish any fresh bank guarantee, as profits have eluded the company in past many quarters. He submitted before the bench that Rs 15,000 crore bank guarantees are lying with the government, and his client's losses are over Rs 1 lakh crore.

"I cannot offer any more surety," he informed the bench.

Justice Mishra noted that this is public money and these dues should be recovered. "Do not tell us that you will pay if you were to make profits... the money must come," he noted.

Justice Shah observed that the telecom industry is the only industry which earned during the Covid-19 pandemic. "After all, this money will be used for public welfare", he said.

Rohatgi argued that his client would have to fold up if orders were issued to clear dues tomorrow. "11,000 employees will have to go without notice, as we cannot pay them," he added.

Senior advocate Abhishek Manu Singhvi, appearing for Bharti Airtel, contended before the court that out of Rs 21,000 crore AGR dues, the company has already deposited a sum of Rs 18,000 crore.

He argued that his client has given a bank guarantee, in excess of demand, to DoT, and supported the proposal for phased repayment of remaining AGR dues. He insisted that the company needs to sit down with the government and calculate the dues. Airtel owes Rs 25,976 crore after paying Rs 18,000 crore, as per the government.

Senior advocate Arvind Datar, representing Tata Telecom, informed the bench that his client has paid Rs 6,504 crore in AGR dues so far, and furnishing a bank guarantee may adversely impact investments in the sector.

The total AGR dues are close to Rs 1.5 lakh crore.

The top court will now take up the matter in the third week of July.

Citing the current dismal aviation scenario, Air India is terminating the services of trainee cabin crew and cabin crew by withdrawing the offer of employment of those who were under training.

As per sources, the new crew and trainee pilots might reduce contracts from five years to one year. Sources said Air India is terminating 1,200 crew and employees who are more than 55-yr-old including 190 trainee pilots.

In a letter reviewed by IANS, Air India has informed an applicant who had been selected as cabin crew in August 2019 subject to successful completion of training.

"On behalf of Air India we would like to thank you for the interest shown by you in joining our organization. However, in view of the current aviation scenario, it would not be possible for Air India to impart any further training to you for engaging your services," the company said.

"In view of the above reasons, which are beyond the control of the company, it has been decided to discontinue your training arrangements and dispense with the offer of engagement with immediate effect. The bank guarantee furnished by you at the time of joining is returned herewith," Air India told the cabin crew.

"Once again on behalf of Air India we thank you for your cooperation and trust that you will appreciate the circumstances under which we are constrained to discontinue the training arrangements," the carrier said.

Unnao, Feb 26: Ever heard of someone wishing a 'bright future' for the dead? In a bizarre incident in Uttar Pradesh's Unnao district, a village head issued a death certificate with the wish for an elderly man who had died last month.

The incident took place in the Sirwariya village in Asoha block where an elderly person Laxmi Shankar died after a prolonged illness on January 22.

His son went to the village head Babulal and requested him to issue a death certificate that he needed for some financial transactions.

The village head wrote in the death certificate -- "Main inke ujjwal bhavishya ki kaamna karta hoon (I wish him a bright future)."

The letter went viral on the social media on Monday after which the village head apologised for the error and issued a new death certificate.
