IIT,Kanpur,India to Develop Nanosatellite-Jugnu

IIT-Kanpur with its nano satellite — `Jugnu’ is ready to set new highs in space research. A team of students, working under the guidance of faculty members of the institute and scientists of Indian Space Research Organisation (ISRO) are set to launch India’s first nano satellite.

Designed life span of the satellite is proposed to be one year. Jugnu`s design will have to overcome many challenges as it will have to face high vibrations even before its ejection. The satellite will also have to survive high doses of radiation that can cause damage to the system’s memory. There are many other functionality constraints on the satellite hardware due to the limited power availability.

The aim of the making and launching of `Jugnu’ is to develop a long term infrastructure and human resources in the IIT-K for future space research programmes in the institute in collaboration with ISRO.

Scientists have used indigenous technology to develop ‘Jugnu’, whose weight and length are 3kg and 34cm respectively, he said, adding an estimated amount of Rs 2.5 crore has been spent to develop the satellite.

The hi-tech cameras fitted in the satellite will send photographs regarding agriculture, weather and soil to the base station.The satellite can also be used to link other big satellites in the space.

Don’t judge States on Wealth and Emissions: Singapore’s climate Envoy

Judging small, rich island nations purely on their wealth and emissions is unfair in climate change negotiations, Singapore’s climate envoy said on Saturday, as pressure builds on more countries to curb carbon pollution. Under the Kyoto Protocol, the U.N.’s main weapon to fight climate change, only 37 industrialized nations are committed to curbs on greenhouse gas pollution between 2008-2012. But the U.N. list in Kyoto’s parent pact that defines rich and developing nations dates from 1992 and wealthy nations such as Argentina, Singapore, South Korea and Malta are still deemed to be developing states under the U.N.’s climate treaties. Under Kyoto, developing nations are exempt from any binding emissions curbs but recent studies show poorer states now contribute more than half of mankind’s greenhouse gas emissions. ore’s chief climate change negotiator, Chew Tai Soo, said Singapore was responsible for 0.3 percent of global greenhouse emissions but faced pressure to curb its emissions because it was rich and had high per-capita carbon pollution. “This approach is flawed as it does not take into account the unique considerations and capabilities of different countries. “It penalizes small countries with small populations without taking into account their limitations,” he told a sustainability conference in Singapore. The city state is one of the world’s wealthiest nations with 2007 per-capita GDP of S$52,994 (US$35,163), according to government figures. Its greenhouse gas emissions are the same as many European countries at about 11 tonnes per person, compared with 20 tonnes for the United States and 4 for China. In a submission to the United Nations last November, Australia said the 1992 U.N. Framework Convention on Climate Change, Kyoto’s parent pact, let many advanced economies off the hook on carbon reduction obligations. “Since the Convention was adopted in 1992 no work has been done to better differentiate the responsibilities of Parties,” the submission said, adding the two annex lists of countries in the Kyoto Protocol were now out of date. Chew said Singapore covered an area a fifth the size of Long Island in New York, was densely populated, lacked natural resources and its agricultural sector was virtually non-existent. “With such economic restraints, we have no food security and are heavily dependent on trade and commerce for survival.” He also said the country was investing in research and development of solar and other clean-energy areas and that a decision to use natural gas in its power stations had slashed carbon emissions.

ISRO,India to launch RISAT, ANUSAT

ANUSAT

ANUSAT

RISAT

RISAT

Bangalore, India: After the successful Chandrayaan-I moon mission, Indian Space Research Organisation is now getting ready for a twin launch – a “breakthrough” Radar Imaging Satellite (RISAT) and ANUSAT, a 35-kg micro-satellite designed by Chennai-based Anna University. Bangalore-headquartered ISRO is targeting a March last week date for launching them on board the indigenously built Polar Satellite Launch Vehicle from the Sriharikota spaceport.

Indian space scientists see the 1,780-kg RISAT as a major milestone for the country as far as remote sensing satellites are concerned. RISAT mission would have a C-band Synthetic Aperture Radar (SAR) payload, operating in a multi-polarisation and multi-resolution mode.

SAR, being an active sensor, operating in the microwave range of electromagnetic spectrum, provides the target parameters such as dielectric constant, roughness, and geometry, and has the unique capability for day-night imaging, and imaging in all weather conditions including fog and haze, and also provide information on soil moisture.

RISAT is capable of taking pictures during night as well and even in cloud-covered conditions, an expertise Indian remote sensing satellites did not have previously.

ANUSAT mission’s main objective is to involve universities in building micro satellites as a means to promote and encourage intra-disciplinary technologies with ISRO’s help. ANUSAT carries a digital store and forward payload for amateur communication.
