DRDO develops Indigenous Unmanned Ground Vehicle

The Indian Army has received its first homemade unmanned ground vehicle, which will be used for surveillance, and to detect nuclear, biological and chemical weapons and mines.The prototype of the vehicle, which has been developed and handed to the Indian Army for trials, is based on an infantry fighting vehicle, the BMP-II, and has been developed by the state-owned Combat Vehicles Research & Development Establishment. It is operating under India's Defence Research and Development Organisation (DRDO).The prototype consists of a drive-by-wire system, which includes electromechanical actuators and drives for the driver interfaces, such as acceleration, brake, gear shifting, steering, clutch, parking brake, etc., said a DRDO scientist. The signals from the engine are acquired by a data acquisition card and displayed in the graphical user interface. The vehicle would be a precursor to the development of a future unmanned battle tank.

ISRO launches beta version of 3D mapping tool - Bhuvan

The common man can now view sharper pictures of any part of the world on their personal computer using satellite images with ISRO today unveiling 'Bhuvan', its version of Google Earth.
Minister of State in the PMO Prithviraj Chavan launched the beta version of the geoportal www.bhuvan.nrsc.gov.in at a day-long workshop of the Astronautical Society of India on "21st Century Challenges in Space -- Indian Context."
The new web-based tool allows users to have a closer look at any part of the subcontinent barring sensitive locations such as military and nuclear installations.
The degree of resolution showcased is based on points of interest and popularity, but most of the Indian terrain is covered upto at least six meters of resolution with the least spatial resolution being 55 meters, an ISRO official said.

ISRO developing 7-satellite constellation to guard the country

The Indian Space Research Organisation (ISRO) is developing a constellation of seven satellites to give a boost to the country's  security apparatus, a top scientist said here Sunday. ISRO chief G. Madhavan Nair said the Indian Regional Navigational Satellite System (IRNSS) was being developed "considering security related issues". Speaking at the Indian Institute of Technology-Delhi, Nair said: "The proposed system would consist of a constellation of seven satellites and a ground support segment. Three of the satellites will be placed in the geostationary orbit and four near the geostationary orbit. "Such an arrangement would mean all seven satellites would have continuous radio visibility with the Indian control stations. The satellite payloads will consist of atomic clocks and electronic equipment to generate the navigational signals," he said. "The system is intended to provide an absolute position accuracy of more than 20 meters throughout India …

BrahMos close to final testing of air-launched version

A top Russian defence official said a new takeoff engine for launching of the missile in air and at extreme high altitudes had been developed.
Alexander Leonov, Director of the Russian Machine Building Research and Production Center, said: "we are ready for test launches."
Leonov was quoted as saying by the Itar-Tass news agency that the initial test firing of the missile would be undertaken from the Sukhoi-30 MKI, but did not specify the exact dates.
After testing, the IAF would be launch customers for the air launched BrahMos cruise missile, which will make the Indian Air Force, the only force in Asia to have such a capability.
The BrahMos is already inducted in its ship to shore role and land-to-land versions in the Indian Navy and Army.
Leonov for the first time disclosed that Moscow and New Delhi were also "very close" to  designing and testing of the submarine launched version of the BrahMos missile.

India’s growing military muscle

The recent launch of an indigenously produced nuclear powered submarine once again brought to fore India’s expanding military capabilities and its ambitions to be a global player. Clearly, when the 6,000-ton Arihant along with the other additional two (or four) of its class are commissioned around 2020 it would be a quantum jump in its strategic posture and assets. Acquisition of a nuclear powered submarines forms part of India’s nuclear doctrine that is based on the concept of triad i.e. developing land, air and sea strike capability and adherence to “No First Use” (NFU). Major nuclear powers consider submersible launched nuclear-tipped missiles critical in terms of providing second-strike capability. Submarines are autonomous under water platforms for launching nuclear-tipped missiles and are relatively safe from enemy action as these are practically noiseless and stealth makes it hard to detect by sonar and radar. Thus they are able to achieve both mobility and surprise. And by esc…

India developing reactor for making hydrogen as tech demonstrator

India has joined the league of countries like South Africa, China, US and Germany which are trying to develop a high temperaturereactor for generating hydrogen on a large scale. Hydrogen can be used as fuel for vehicles, besides other scientific applications in the future.
The technology demonstrator reactor would be ready by 2015 and work is currently in progress on the project, Anil Kakodkar, Atomic Energy Commission chairman told reporters here on Sunday.
Srikumar Banerjee, director, Bhabha Atomic Research Centre (BARC), said the reactor would generate hydrogen by splitting water. The reactor's operational efficiency would be very much enhanced. Already efforts are on in countries to develop such a reactor, he said.
"The programme is on course. Technology development is on, we are developing the reactor design, materials, material processing capabilities. The actual construction of the reactor will take some time," he said.
Kakodkar said India would have su…

India built N-sub in Kalpakkam under codename 'PRP'

The secrecy attached to the development of the indigenous nuclear submarine project is almost legendary.
What’s little known is the extent to which the Indian N-establishment went to conceal the research not only from the public but also large sections of the scientific community within the Department of Atomic Energy (DAE).
For almost nine years, most staff working at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam believed the Plutonium Recycle Project (PRP) in the complex was used only for that purpose, that is recycling plutonium.
But with the launch of INS Arihant on July 25, top DAE officials have finally begun to lift the veil and reveal that they were actually building the core (nuclear reactor and propulsion systems) of the submarine as well as the land-based version of the hull of the indigenous vessel, which served as the technology demonstrator of the main vessel, within the PRP unit. For those in the know, even the term ‘PRP’ denoted the N-sub…

BrahMos Block-II Land Attack version ready for induction after test firing

Jaisalmer: The Block-II version of the BrahMos land attack cruise missile successfully completed its fourth and final test firing on Wednesday and has now been declared ready for induction. In a test firing at the Pokhran test range in Rajasthan, the missile went on to score a "bull's eye" hit on a target 25km away on Wednesday.The previous test-firing of the Block-II land attack version took place 29 March 2009."The missile took off successfully and hit the desired target at Ajasar area range situated 25 km away from launching pad, meeting all mission parameters," defence sources said.The missile had failed its first test firing, leading to a second test in short order which was a success."With this launch, the requirement of Army for the land attack version with Block-II advanced seeker software with target discriminating capabilities has been fully met and this version is ready for induction," defence sources said.The Block-II version with sophisti…

US satellites to use ISRO platform

India's technology safeguards agreement signed with US during the recent state visit of Secretary of State Hillary Clinton in New Delhi will soon yield fruitful results for the space research program of the country. It will enable India to launch smaller satellites for United States at much competitive prices using indigenously developed rockets.Indian Space Research Organization (ISRO) Chairman, Madhavan Nair said, "Space cooperation with the US has been the agenda of the government. The pact will enable US made satellites or with components of US to be launched from India."He said that the space body is already providing satellite launching services to various nations at very economical prices and more countries to avail the service on mutually agreeable terms. Country has been developing heavier rocket GSLV-MKIII that will help to further reduce the cost of sending a satellite to space.Mr. Nair, while launching an indigenous GIS mapping software in Ahmadabad, added, &…
