India's first defence satellite GSAT-7 launched successfully

August 30, 2013

GSAT-7Bangalore, Aug 30: India's first exclusive defence satellite GSAT-7 was successfully launched by European space consortium Arianespace's Ariane 5 rocket from Kourou spaceport in French Guiana today, giving a major push to the country's maritime security.

Indian Navy would be the user of the multi-band home-built communication spacecraft, expected to be operational by September end.

The Rs 185-crore GSAT-7, the country's maiden dedicated spacecraft for Defence applications, was launched during a 50-minute launch window which started at 2 am, and it was telecast live by Doordarshan.

After a flight of almost 34 minutes, the satellite was injected into a Geosynchronous Transfer Orbit (GTO) of 249 km perigee (nearest point to earth), 35,929 km apogee (farthest point to earth) and an inclination of 3.5 degree with respect to the equator.

During August 31-September 4, three orbit-raising operations will be performed by Indian Space Research Organisation (ISRO) to place the satellite into geostationary orbit of 36,000 km above the equator.

By September 14, GSAT-7 is planned to be positioned in its orbital slot of 74 deg East longitude and subsequently the satellite's communication transponders will be switched on.

The frequency bands of GSAT-7 will help space-based marine communications. It has coverage over India landmass as well as surrounding seas.

"It's important from security and surveillance points of view", an ISRO official said.

According to a senior space scientist, so far the Navy had limitation from line of sight and ionospheric effects, among others, as far as space-based communications were concerned.

It was thought essential to have an integrated platform for the Navy's exclusive use.

Earlier, satellite communication in ships was through Inmarsat, a major provider of global mobile satellite communications services.

The state-of-the-art satellite carrying payloads operating in UHF, S, C and Ku bands, had a lift-off mass of 2625 kg and is based on ISRO's 2500 kg satellite bus with some new technological elements, including the antennae.

According to ISRO, GSAT-7 is an advanced communication satellite to provide wide range of service spectrum from low bit rate voice to high bit rate data communication. Its payload is designed to provide communication capabilities to users over a wide oceanic region including the Indian land-mass.

The launch cost for ISRO is around Rs 470 crore, including insurance.

ISRO cannot launch heavy satellites like GSAT-7 as its home-grown GSLV rocket, with indigenous cryogenic stage, is still at works and needs two successful flights before it is declared operational.

In addition to GSAT-7, the Ariane 5 orbited another spacecraft EUTELSAT 25B/Es'hail.

EUTELSAT 25B/Es'hail 1 – which rode in the top position of the Ariane 5 payload "stack" – separated first, some 27 minutes after liftoff.

At approximately 34 minutes into the flight, the lower passenger – GSAT-7 – was deployed, completing the mission.

Indian Ambassador to France, Arun Singh and Director of Bangalore-based ISRO Satellite Centre, S K Shivakumar, were among those who witnessed the launch.

Singh said the launch event is also a reflection of strategic partnership between India and France.

Shivakumar said GSAT-7 would be operational by next month-end.

Apr 11: India has sent back 20,473 foreigners who wanted to return to their countries following the Covid-19 global pandemic, it was revealed on Friday (April 10).

"So far, we have successfully evacuated 20,473 foreign nationals as of yesterday. This is an ongoing process," said Dammu Ravi, Coordinator on Covid-19 issues at the Ministry of External Affairs, MEA.

"This involves several countries," Ravi said during the daily government briefing on Covid-19, although he could not list the countries offhand. "We are receiving excellent cooperation from governments all over the world for this process."

Many foreigners, especially tourists, were stranded in India when domestic and international flights were abruptly cancelled last month in a bid to curb transmission of the coronavirus.

The Ministry of Tourism has asked stranded foreigners to get in touch with the government through a special portal started for the purpose, through their embassies in India and other sources to facilitate their evacuation if they wished to head home.

As of Friday evening, the Ministry of Health and Family Welfare had confirmed 6,761 Covid-19 cases in India, of whom 515 patients have been cured.

There were 206 deaths reported from across the country.

Two states, Punjab and Orissa, have extended the ongoing lockdown until April 30.

Prime Minister Narendra Modi will consult state chief ministers on Saturday to decide whether to extend the country-wide lockdown, which is due to end at midnight on April 14.

New Delhi, Jun 24: A litre of diesel on Wednesday was more expensive than a litre of petrol after the price of the former was hiked by 48 paise on the 18th successive day of fuel price revisions. While petrol price remained unchanged for the first time since June 7, diesel prices maintained upward trajectory to touch new highs.

It is for the first time in Delhi that diesel has become more expensive than petrol. A litre of the fuel now costs ₹79.88 as against ₹79.76 for a litre of petrol, as per a report in news agency ANI.

While surging fuel prices may generate much-needed revenue for governments, it would also have a detrimental impact on household budgets. The spike in diesel prices also has a wider impact on the transport and agricultural sectors which are largely dependent on the fuel.

The widest gap between the prices of the two fuels was on June 18 of 2012 when a litre of petrol was at ₹71.16 in Delhi while diesel was at ₹40.91. On June 28, the gap between the two fuels was 31.17 per litre in Mumbai. Around that time, there was a spurt in sales of diesel passenger vehicles while demand for such vehicles has come down significantly in current times. This has also led many manufacturers to ditch diesel engines completely.

The current trend of fuel price hikes are unlikely to do demand for petrol vehicles much good either.

Daily price revisions of the two fuel had been temporarily halted for 83 days till it was resumed on June 7.

India's demand for fuel doubled in May and has been steadily rising in June with the easing of restrictions. Indian refineries have already scaled up crude processing with Indian Oil Corp, the country's top refiner, looking to operate its plants at about 90% capacity in June.

The rising fuel prices, however, have resulted in political uproar with Congress leading the charge against the central government and accusing it of penalising consumers by imposing high taxes. A demand for including fuel prices under Goods and Services Tax (GST) has also been renewed by many but it is highly unlikely that it would happen. With oil companies looking to cut back on their previous loses and governments - central as well as states - aiming to generate revenue after tumultous weeks of lockdown, fuel price hikes are likely to stay till at least the end of June.
