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.

United Nations, May 21: At least 19 million children in parts of Bangladesh and India are at "imminent risk" from flash flooding and heavy rain as Cyclone Amphan makes landfall and the state of West Bengal is expected to take a direct hit from the powerful storm, the UN's children agency has warned.

The extremely severe cyclonic storm Amphan made a landfall at Digha in West Bengal and Bangladesh on Wednesday, leaving a trail of destruction. At least three persons were killed in India and seven in Bangladesh.

The UNICEF said that at least 19 million children in parts of Bangladesh and India are at “imminent risk from flash flooding, storm surges and heavy rain as Cyclone Amphan makes landfall.”

West Bengal, “home to more than 50 million people, including over 16 million children, is expected to take a direct hit from the powerful storm,” the UN agency said in a statement on Wednesday.

The UNICEF said it is also very concerned that the COVID-19 could deepen the humanitarian consequences of Cyclone Amphan in both the countries. Evacuees who have moved to crowded temporary shelters would be especially vulnerable to the spread of respiratory diseases like COVID-19, as well as other infections.

“We continue to monitor the situation closely,” said UNICEF Regional Director for South Asia Jean Gough.

“The safety of children and their families in the areas that will be impacted is a priority and it is good to see that the authorities have planned their urgent response factoring in the on-going COVID-19 pandemic.”

Across the region, the UNICEF is “working closely with the governments of Bangladesh and India and stands ready to support humanitarian operations to reach children and families affected by Cyclone Amphan.”

Based on the storm’s current trajectory, Cox’s Bazar in Bangladesh – now sheltering over 850,000 Rohingya refugees – is likely to experience high winds and heavy rains which may cause damage to homes and shelters in the refugee camps and Bangladeshi communities. This population is already highly vulnerable and cases of COVID-19 have recently been confirmed in the camps and host communities.

The UNICEF said it is working with the Deputy Commissioner’s Office in Cox’s Bazar, the Office of the Refugee Relief and Repatriation Commissioner, and humanitarian partners to help ensure Bangladeshi and Rohingya children and families remain protected.

These efforts include raising awareness among Rohingya and Bangladeshi communities on cyclone preparedness and prepositioning emergency life-saving water, sanitation, hygiene and medical supplies to meet immediate humanitarian needs.

Meanwhile, UN Secretary-General Antonio Guterres’ spokesperson Stephane Dujarric said at the daily press briefing that UN teams on the ground continue to work with the Government of Bangladesh to prepare and support those in need in the wake of the cyclone.

“Given the current pandemic, this support includes distributing personal protective equipment, disinfectants and other materials to evacuation shelters. To reduce the person-to-person contact during the delivery of aid, e-cash distributions will be used,” he said adding that the UN along with its partners is mobilising more than 1,700 mobile health teams and preparing for emergency food deliveries.

“The Super Cyclone is taking a westerly trajectory towards India, but nearly 8 million people in Bangladesh remain at risk,” he said adding that the Bangladesh government has evacuated more than 2 million people in high-risk areas.

Bengaluru, Apr 30: Shares of Glenmark Pharmaceuticals Ltd rose almost 9% on Thursday after the Indian drugmaker got an approval to conduct clinical trials with antiviral drug favipiravir, seen as a potential treatment for COVID-19.

Favipiravir, manufactured under the brand name Avigan by a unit of Japan's Fujifilm Holdings Corp and approved for use as an anti-flu drug in the Asian island country in 2014, has been effective, with no obvious side-effects, in helping coronavirus patients recover, a Chinese official told reporters at a news conference last month.

"After having successfully developed the API and the formulations ... Glenmark is all geared to immediately begin clinical trials on favipiravir on COVID-19 patients in India," Sushrut Kulkarni, executive vice-president for Global R&D, Glenmark Pharmaceuticals, said in a statement. 

The Drug Controller General of India, the country's drug regulator, did not immediately respond to Reuters request for comment.

On Wednesday, another Indian pharmaceutical company, Strides Pharma Science Ltd, said it had developed and commercialized favipiravir antiviral tablets, and had applied to Indian drug authorities to start trials.

Shares of Mumbai-based Glenmark Pharmaceuticals, which rose as much as 8.9% to 359 rupees ($4.78), was trading up 5.9%, as of 0407 GMT.
