PICTURE: MiG-29K gets on board Indian aircraft carrier

ith work on the Indian navy's future aircraft carrier the INS Vikramaditya now 90% complete, an RSK MiG-29K fighter has been placed aboard the vessel for the first time.
Pictured on the carrier's deck at the Sevmash dockyard in Severodvinsk, northern Russia during November, aircraft Side 311 was deployed using a crane to serve as a mock-up only.
According to Sevmash, the Vikramaditya will start sea trials in May 2012, with these to involve take-offs and landings using two industry-owned aircraft. One is a purpose-built MiG-29K, while the other is a MiG-35D two-seat demonstrator now being modified after the crash of a MiG-29KUB trainer during trials in 2011.

Originally introduced to service with the Russian navy in 1987 as the Baku, but deactivated in 1992, the modified Vikramaditya now features a "ski-jump" ramp and three arrestor wires to support fighter operations. New Delhi's total investment in the ship is worth around $2 billion, with Sevmash expecting it to be commissioned into service on 4 December 2012 - Indian navy day.
Russia has so far delivered 11 of the 16 MiG-29K/KUBs ordered for the Indian navy under a 2003 deal worth $530 million, with the remainder due to be shipped to Goa before the end of 2011.
India also this year firmed up an option for 29 more navalised MiG-29s to equip its future homegrown aircraft carriers.

India to ferry heaviest foreign satellite in August

ndia will ferry two foreign satellites - French and Japanese - on board its Polar Satellite Launch Vehicle (PSLV-C21) rocket in August this year for a price, said a senior official. 

"The next rocket launch will be in August. We will be sending our PSLV rocket with French satellite SPOT 6 (800 kg) and a small Japanese satellite weighing around 15 kg. Though the rocket is called PSLV-C21 it will go before PSLV-C20," P.S. Veeraraghavan, director, Vikram Sarabhai Space Centre (VSSC), told IANS. 

The Thiruvananthapuram based VSCC is part of India's space agency Indian Space Research Organisation (ISRO). 

ISRO's commercial arm Antrix Corporation Limited (Antrix) has entered into a commercial Launch Services Agreement with Astrium SAS, a company under EADS, France for launching SPOT-6, an advanced remote sensing satellite. 

What is interesting is that the 800 kg SPOT-6 built by Astrium SAS will be the heaviest third party payload thatISRO will be carrying after the 350 kg Italian satellite Agile it carried in 2007, officials said. 

As the total luggage will be around 815 kg, ISRO will be using its Core Alone variant of PSLV (rocket without its six strap on motors). 

The mission will take ISRO's total tally of ferrying foreign satellites to 29. 

ISRO has been carrying foreign satellites since 1999 initially as an add-on luggage to its own satellite. 

It was with Agile satellite that ISRO started flying a full commercial rocket. 

According to Veeraraghavan, the space agency would launch SARAL satellite - an Indo-French initiative - using PSLV-C20 rocket after the August launch.

India-New ISRO system to cut your flying time

 Domestic air passengers in the country will soon be able to reach their destinations in shorter time. The Space Applications Centre (SAC) of Indian Space Research Organisation (ISRO) in Ahmedabad has developed payloads for a project called GPS-Aided Geo Augmented Navigation (Gagan) which will enable better Navigation of flight routes to cut down the distance and time between two places in the country. 

Gagan is a joint project of ISRO and Airports Authority of India (AAI) to manage flights in a better and more reliable way. Until now, the management of flights in the country has been based on GPS data obtained from US. 

With the help of Gagan, pilots and the Air Traffic Control (ATC) at airports will be able to locate the exact positioning of an aeroplane, regardless of wherever it is, with the help of satellites. "At present, aeroplanes can communicate their locations and positions directly with the airports only when they are within a certain range. Hence aeroplanes do not take a linear path but fly such that they are always within the range of one airport after another," said AS Kiran Kumar, director of SAC. 

Talking about other ways in which AAI will be able to benefit from Gagan, Kumar said, "It will also help in monitoring the speed of the wind blowing from the opposite direction along the path of the flight. As wind speeds can significantly reduce the speed of the aeroplane and increase the travel time, the route could be modified accordingly to divert such winds." 

The first Gagan navigation payload slated on GSAT-8, was launched on May 21, 2011. The second Gagan payload is scheduled to be launched on GSAT-10 around August 2012. "Gagan can become functional after the second payload is launched," said Kumar. 

The main payload for Radar Imaging Satellite (RISAT-1) which was launched on Thursday was built in SAC. RISAT-1 uses microwaves which can penetrate clouds and take images if the earth surface bit during day and night and provide critical data inputs for a range of applications. Apart from building the payload, a film to explain the details and function of RISAT-1 was also made by senior producer at development and educational communication unit at SAC campus.

Indian rocket successfully launches Risat-1 satellite

SRIHARIKOTA : On an early Thursday morning, an Indian rocket successfully launched into orbit a microwave Radar Imaging Satellite (Risat-1) from the spaceport here inAndhra Pradesh, around 80 km from Chennai.

The indigenous Risat-1, with a life span of five years, would be used for disaster prediction and agriculture forestry and the high resolutionpictures and microwave imaging could also be used for defence purposes as it can look through the clouds and fog.

At exactly 5.47 a.m., the rocket - Polar Satellite Launch Vehicle C19 (PSLV-C19) - standing 44.5 metres tall and weighing 321 tons and with a one-way ticket, hurtled towards the skies ferrying the 1,858 kg Risat-1 after unshackling itself from launch pad No.1.

With a rich orange flame at its tail and a plume of white smoke, the rocket ascended towards the blue sky amidst the resounding cheers of Isro scientists and media team assembled at the launch centre.

People perched atop nearby buildings too happily clapped as PSLV-C19 went up.

Space scientists at the new rocket mission control room of the Indian Space Research Organisation (Isro) were glued to their computer screens watching the rocket escaping the earth's gravitational pull.

The Isro-made Risat-1 is the heaviest luggage so far ferried by a PSLV since 1993.

At around 17 minutes into the flight, PSLV-C19 delivered Risat-1 into a polar circular orbit at an altitude of 480 km and an orbital inclination of 97.552 degrees.

Isro, with its network of ground stations, monitored its health.

"PSLV-C19 mission is a grand success. This is the 20th successive successful flight of PSLV. India's (indigenously built) first radar imaging satellite was injected precisely into orbit," Isro chairman K. Radhakrishnan said after the launch.

For Isro, this is the first launch this fiscal as well as in the calendar year.

Remote sensing satellites send back pictures and other data for use. India has the largest constellation of remote sensing satellites in the world providing imagery in a variety of spatial resolutions, from more than a metre ranging up to 500 metres, and is a major player in vending such data in the global market.

With 11 remote sensing/earth observation satellites orbiting in the space, India is a world leader in the remote sensing data market. The 11 satellites are TES, Resourcesat-1, Cartosat-1, 2, 2A and 2B, IMS-1, Risat-2, Oceansat-2, Resourcesat-2 and Megha-Tropiques.

Risat-1's synthetic aperture radar (SAR) can acquire data in C-band and would orbit the earth 14 times a day.

In 2009, Isro had launched 300 kg Risat-2 with an Israeli built SAR enabling earth observation in all weather, day and night conditions.

With Thursday's launch the PSLV rocket has launched successfully 53 satellites out of 54 it carried - majorly remote sensing/earth observation satellites both Indian and foreign - and has been a major revenue earner for Isro.

The one failure happened in 1993 when the satellite was not able reach the orbit.

The rocket that delivered Risat-1 in the space is Isro's four stage PSLV's upgraded variant called PSLV-XL.

The letters XL stand for extra large as the six strap-on motors hugging the rocket at the bottom can carry 12 tonnes of solid fuel as against the base version that has a fuel capacity of nine tonnes.

The PSLV's four stages are fuelled with solid and liquid propellants. The first and third stages are fuelled by solid fuel while the second and fourth stages are powered by liquid fuel.

Isro had used the PSLV-XL variant for its Chandrayaan-1 moon mission in 2008 and for launching the GSAT-12 communications satellite in 2011.

India-Boeing to help set up transonic tunnel facility


Global aircraft major Boeing is setting up a transonic wind tunnel facility in Hyderabad.
The facility, the first of its kind in the country and under ‘Defence offsets', could involve an expenditure of Rs 400-450 crore.
The Defence Research and Development Organisation (DRDO) will use the facility for its research studies. It is expected to come up in 3-4 years, according to Mr K.V.R. Murthy, Integrated Financial Advisor, DRDO.
A wind tunnel is an enclosure that is equipped to test the aerodynamic features of various aircraft shapes. It can also test space vehicles.
A transonic tunnel is a high-speed tunnel that can generate speeds up to Mach 1.4 (Mach is the speed of sound).

OFFSET COMMITMENTS

The Defence Ministry's offset policy stipulates that a minimum of 30 per cent of the value of a large contract bagged by a foreign company or a consortium in Defence projects has to be sourced from lndia.
Boeing has the largest offset commitment in the country, according to Mr Dinesh S. Keskar, Senior Vice-President, Asia-Pacific & India sales for Boeing Commercial Airplanes.
In a recent interaction with Business Line in Hyderabad, Mr Keskar said the company was active in the Defence and aerospace sectors and has collaborations with HAL, BEL, and the Tata group.
It is also looking at opportunities with companies that possess engineering expertise, such as Mahindras and L&T.
In the last five years Boeing has won a major contract to supply 68 aircraft to Air India. In 2009, the Government of India purchased eight Boeing P-81 long-range maritime reconnaissance and anti-submarine aircraft.
In June 2011, the Defence Ministry signed an agreement with the US Government to acquire 10 Boeing C17 Globemaster III airlifters. Some of these deals carry Defence offsets.

HYPERSONIC TUNNEL

The DRDO is also in the process of setting up its own Rs 350-crore Hypersonic Wind Tunnel facility, also in Hyderabad.
At present the country has only one wind tunnel facility at the National Aerospace Laboratory, Bangalore, which is 40 years old. This will also be upgraded, Mr Murthy said.

India all set to develop reusable rockets: DRDO


After the successful launch of Agni-V Inter-Continental Ballistic Missile (ICBM), India is all set to develop reusable rockets which will combine the technologies of both ballistic and cruise missiles.
As part of plans to develop reusable ballistic missiles, Defence Research and Development Organisation will test indigenously developed scram jet engine next year, DRDO Chief VK Saraswat said in an interview to Doordarshan.
“We have propulsion technology, we have re-entry technologies, we have the technology which can take a re-entry system which will deliver a payload and have yet another re-entry system which will bring the missile back when it re-enters the atmosphere on its return journey,” he said.
“We have demonstrated the performance of a scram jet engine operating at Mach six speed (six times the speed of sound),” he said.
On the range of Agni-V missile which was successfully test-fired recently off Odisha coast, the DRDO chief said with moderate modifications, “it can be extended to any range which is of our interest.”
On technological capability available with the agency, he said, “DRDO has built the necessary technologies, production infrastructure and design capability for developing a booster or a sustainer… We have the capability to develop a re-entry nose cone which can withstand higher temperature and velocity.”
Reacting to reports that India does not possess sufficient indigenous technology for missile guidance systems, Saraswat said Agni-V has used a completely indigenous and high precision missile guidance system with “0.001 degrees of per hour accuracy.”
On criticism that DRDO sometimes does not live up to expectations, he said the agency was as good as its counterparts in advanced countries.
“Light Combat Aircraft (LCA), F-18 and Eurofighter took similar number of years and cost wise they were three times more than what we have put in our LCA,” he said.
On development of Kaveri engine, Saraswat said it too has performed well and was, “flown an IL-76 aircraft in Russia, 55 hours of successful flight… We are going to upgrade it so that it can be used in India’s LCA Mark-II and future systems.”

Javelin missile, R&D coop to feature in US-India talks


As New Delhi looks to translate its relationship with the US into badly needed high technology, the government is readying for meetings tomorrow with America’s key gatekeeper of military technology, the visiting assistant secretary of state for political military affairs, Andrew Shapiro.
High on New Delhi’s technology agenda is Washington’s reluctance to transfer military knowhow, of the kind needed for building the FGM-148 Javelin anti-tank missile in India. The Army wants the Javelin for its ground forces, to enable two-man infantry teams to fire $40,000 missiles at $10 million enemy tanks 2,500 metres away and destroy them 95 per cent of the time. The Javelin sale, potentially a billion-dollar (Rs 5,000 crore) contract for US companies, Raytheon and Lockheed Martin, has been blocked by Shapiro’s office, the department of political military affairs. The technology, it has been deemed, is too sensitive to transfer.
Shapiro’s 10-person team will be discussing this issue with India’s defence and foreign ministries (MoD and MEA), which regard overly-strict US licensing and export controls as key obstacles in “operationalising”, or obtaining tangible benefits from the growing strategic convergence between the US and India.
In clearing any transfer of high technology like the Javelin, Shapiro’s primary consideration is strategic: would technologically enabling India enhance long-term US strategic interests, without threatening America’s lead in military technology. Growing pressure from American senators and representatives complicates Shapiro’s decision-making. Fearing the declining US defence budget will cause job losses in their constituencies, American legislators are willing to back technology transfer to India, if that is what it takes to get orders from the world’s biggest buyer of foreign weaponry.
A likely example of this is the Global Hawk Block 30, a high-altitude, long-endurance (HALE) unmanned aerial vehicle (UAV), which flies 36-hour unmanned missions to watch over vast expanses of territory or water. After the latest US defence budget cuts, the US Air Force has cancelled orders for Global Hawks, 13 of which have already been built or are close to completion by Northrop Grumman. The politically influential company, aided by US Congressmen in whose constituencies the UAV is built, are pressuring the US government to find alternative buyers. There are 13 Block 30 Global Hawks almost ready, which will now be mothballed.
Savvy bargaining by India could get it the Block 30 Global Hawk and perhaps even the technologies that go into it, believes Manohar Thyagaraj, an expert on US-India military relations.
“If India were to express interest, US Congressmen would mount pressure on Shapiro to share the technology. But India tends to engage only the US administration; it has put very little effort into building relationships on Capitol Hill. When Congress gets onto something, it acquires real momentum. New Delhi has not yet understood that engaging Congress is as important as engaging the administration,” says Thyagaraj.
India’s key technology player, the Defence R&D Organisation (DRDO), has figured out the opportunity that lies in declining Western defence budgets. DRDO chief V K Saraswat declared during the Defexpo India 2012 defence exhibition on March 31, “Global economic recession is leading to capacities and capabilities in the international market that we can exploit. So, it will be an era of US and European agencies coming and trying to work with us and we will exploit this.”
Shapiro’s department of political military relations must okay all such joint ventures. US defence giant Raytheon is learnt to be keen on working with DRDO for developing technologies that can detect improvised explosive devices (IEDs), the roadside bombs that took a heavy toll of US lives in Iraq and Afghanistan, and that are now being used to deadly effect by Maoist insurgents in India. With US government funding, Raytheon has already developed a technology called SAVI (Seismic Accoustic Vibration Imaging), which uses acoustic reflections to detect buried IEDs. But budgetary cuts have dried up Raytheon’s funding, and it is looking towards India for partnership in developing SAVI into a deployable military system.
“The DRDO’s funding and scientific base is ideal for reviving such a project; and both sides would profit from selling the SAVI system to the Indian military and abroad. If India comes to the table with money, it would be well placed to negotiate access,” says a top DRDO official.
The dialogue on Monday will be followed by a succession of others. The US-India-Japan trilateral is scheduled for April 22 in Tokyo, followed by the US-India Strategic Dialogue in Washington in May and the US-India Homeland Security dialogue in June.
