Sriharikota: India is reading to launch its fifth regional navigation satellite on Wednesday from its spaceport here, a senior space agency official said on Tuesday.

“The countdown (T-48) is going on smoothly since it was started on Monday at 09:30am. The launch authorisation board will take the final call on early morning tomorrow (Thursday) for the final countdown (T-10),” Indian Space Research Organisation’s (ISRO) satellite director M. Annadurai told IANS.

The 320-tonne 44-metre rocket (PSLV-C31) will lift-off from the second launch pad at the Satish Dhawan space centre here at 9.31 a.m. and deploy the 1,425 kg fifth navigation satellite into as sub-geosynchronous orbit 19 minutes and 20 seconds later at an altitude of 503 km from above the earth.

“Besides checking all launch systems and the satellite onboard, the rocket’s tanks are being filled with liquid fuel in all its four stages,” Annadurai said.

As part of the Indian Regional Navigation Satellite System (IRNSS), comprising seven spacecraft, the fifth satellite (IRNSS-1E) will also aid terrestrial, air and maritime transport, besides giving standard positioning services at pat with global positioning system to all users.

The navigation system will also be used for disaster management, vehicle tracking and fleet management, integration with mobile phones, mapping and geodetic data capture, visual and voice navigation for drivers and others.

Till date India has launched four regional navigational satellites (IRNSS-1A, 1B, 1C and ID) as part of a constellation of seven satellites to provide accurate position information service to users across the country and the region, extending up to an area of 1,500 km.

“The system will provide two types of services – standard positioning services to all users and restricted services to authorized users,” Annadurai added.

Each satellite costs about Rs.150 crore and the polar satellite launch vehicle (PSLV-XL) version rocket Rs.130 crore.

The constellation is planned to be completed this year, with the launch of sixth and seventh satellites in February and March.

The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014 and the fourth on March 2015.

The satellite’s payload will transmit navigation service signals to users, operating in L5-band and S-band. An accurate rubidium atomic clock is part of the navigation payload.

The spacecraft is also carrying corner cube retro reflectors for laser ranging.

The satellite has 12-year lifespan. (IANS)

  • Harsh Vardhan, India’s Union Minister, stated that environmental protection, which is a part of the country’s culture, has been fading away
  • The Environment minister blames the modern lifestyle behind this problem
  • He also stressed that the issue of global warming is taken seriously and attempts are underway in all organizations

July 08, 2017: During a plantation drive at a District Park in Paschim Vihar that marked the beginning of ‘Van Mahotsav’ celebrations, the Union Minister Harsh Vardhan stated that Environmental protection is a significant part of the Indian culture.

Blaming the present and modern day lifestyle habits, he notes that we are forgetting our culture and letting the environment concerns eliminate from it.

Stressing the importance of scientific research, the Environment Minister urged science to solve the basic problems such as water and sanitation. He suggests the scientists to “start from the grassroots level”

He also claimed that India could have set up a big example for the whole world had it stuck and continued with environmental protection in accordance with its culture. He reminded us that water, forests, air, and land are a matter of serious concern.

Dr. Vardhan also expanded that the issue of climate change and global warming is a burning issue and that all organizations of the government are making sincere efforts to take effective actions.

In times of potential danger to humanity, the minister said that ‘environmental soldiers’ are necessary for the country.

ISRO is working in the field of carbon emissions. The International Solar Alliance (ISA), with the cooperation of France, is a Prime Minister’s initiative to address climate change.

On this special occasion, the efforts of Anil Madhav Dave, a former environmental minister were also acknowledged.

Indian Space Programme deserves kudos for sending a record 104 Satellites into the Orbit at one go

According to a chinese daily, even though the recent record-breaking accomplishment of Indian space program was marvelous, it still has a long way to go

Beijing, Feb 16, 2017: India deserves kudos for sending a record 104 satellites into the orbit at one go but it was way behind than China in space technology, a Chinese newspaper said on Thursday.

An editorial in the state-run Global Times said by smashing the previous Russian record of putting 37 satellites into the orbit in 2014, India’s frugal space exploration offered “food for thought for other countries”.

 NewsGram brings to you current foreign news from all over the world.

India did a good job but has a long way to go as there still was no Indian astronaut in space and the plan to establish a space station was yet to take off, the paper said.

“This is perhaps the first widely followed world record India has made in the field of space technology. The Indians have reason to be proud,” the daily said.

NewsGram brings to you top news around the world today.

“However, the space technology race is not mainly about the number of satellites at one go. It’s fair to say the significance of this achievement is limited. In this regard, Indian scientists know more than the Indian public, who are encouraged by media reports.

“It’s a hard-won achievement for India to reach current space technology level with a relatively small investment. It offers food for thought for other countries. India launched a lunar probe in 2008 and ranked first among Asian countries by having an unmanned rocket orbit Mars in 2013.

“Nonetheless, the development of a country’s space technology is determined by the size of its input.

“The US space budget in 2013 was $39.3 billion, China $6.1 billion, Russia $5.3 billion, Japan $3.6 billion and India $1.2 billion.

“As India’s GDP is about one-fifth to one-fourth that of China’s, the share of investment in space technology in India’s GDP is similar to that of China’s.

Check out NewsGram for latest international news updates.

“There is another figure that deserves attention. India’s defence budget is about one-third of China’s, a higher percentage of GDP than that of China.”

It said the Indian space programme was based on certain considerations, including an ambition to make New Delhi a great power.

Also, India felt it should remain present in space technology development, given its close links with military, the daily said.

“On the whole, India’s space technology still lags behind the US’ and China’s. It has not yet formed a complete system.

“There is no Indian astronaut in space and the country’s plan to establish a space station has not started.” (IANS)

Chennai, October 28, 2016: Indian space agency ISRO is aiming for a world record by putting into orbit 83 satellites — two Indian and 81 foreign — on a single rocket in early 2017, a top official of Antrix Corporation said.

He said the company’s order book stands at Rs 500 crore while negotiations are on for launch order for another Rs 500 crore.

NewsGram brings to you latest new stories in India.

“During the first quarter of 2017 we plan to launch a single rocket carrying 83 satellites. Most foreign satellites are nano satellites,” Rakesh Sasibhushan, Chairman-cum-Managing Director of Antrix Corporation told IANS.

Antrix Corporation is the commercial arm of Indian Space Research Organisation (ISRO).

He said all the 83 satellites will be put in a single orbit and hence there will not be any switching off and on of the rocket.

The major challenge for the proposed mission is to hold the rocket in the same orbit till all the satellites are ejected.

He said ISRO will use its Polar Satellite Launch Vehicle XL (PSLV-XL) rocket variant for the record launch.

For ISRO, launch of multiple satellites at one go is not a new thing as it has done it several times in the past.

Go to NewsGram and check out news related to political current issues.

According to Sasibhushan, the total payload/weight carried off into space by the PSLV-XL rocket will be around 1,600 kg.

Citing non-disclosure agreements, Sasibhushan declined to name the clients whose satellites ISRO will put into orbit.

He said some satellites belong to clients whose satellites ISRO put into orbit in the past.

Meanwhile, ISRO is conducting high-altitude tests with its own cryogenic engine that is expected to power the heavier rocket Geosynchronous Satellite Launch Vehicle-Mk III (GSLV Mk III).

Look for latest news from India in NewsGram.

The GSLV Mk III has a capacity to carry around four tonnes of load.

The rocket is scheduled to be flown in January 2017.

The GSLV Mk III rocket is expected to save precious foreign exchange for India as it pays to launch heavier satellites through foreign space agencies.

In an interaction, ISRO Chairman A.S. Kiran Kumar said the agency is looking forward to develop four-tonne communication satellites that will give the same output as a six-tonner. (IANS)
