Integrated Space Cell
The Integrated Space Cell was the nodal agency within the Government of India which oversees the security of its space based military and civilian hardware systems. It was to be jointly operated by all the three services of the Indian Armed Forces, the civilian Defence Research and Development Organisation and the Indian Space Research Organisation (ISRO). This agency was Superseded by Defence Space Agency. Description The Integrated Space Cell had been set up to utilise more effectively the country's space-based assets for military purposes and to look into threats to these assets. It functioned under the Integrated Defense Services headquarters of the Indian Ministry of Defense. This command leveraged space technology including satellites. Unlike an aerospace command, where the air force controls most of its activities, the Integrated Space Cell envisaged cooperation and coordination between the three services as well as civilian agencies dealing with space. The armed forces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HySIS
HySIS (Hyperspectral Imaging Satellite) is an Earth observation satellite which will provide hyperspectral imaging services to India for a range of applications in agriculture, forestry and in the assessment of geography such as coastal zones and inland waterways The data will also be accessible to India's defence forces.

Government Of India
The Government of India (ISO: ; often abbreviated as GoI), known as the Union Government or Central Government but often simply as the Centre, is the national government of the Republic of India, a federal democracy located in South Asia, consisting of 28 union states and eight union territories. Under the Constitution, there are three primary branches of government: the legislative, the executive and the judiciary, whose powers are vested in a bicameral Parliament, President, aided by the Council of Ministers, and the Supreme Court respectively. Through judicial evolution, the Parliament has lost its sovereignty as its amendments to the Constitution are subject to judicial intervention. Judicial appointments in India are unique in that the executive or legislature have negligible say. Etymology and history The Government of India Act 1833, passed by the British parliament, is the first such act of law with the epithet "Government of India". Basic structure The gover ...

Military Satellite
A military satellite is an artificial satellite used for a military purpose. The most common missions are intelligence gathering, navigation and military communications. The first military satellites were photographic reconnaissance missions. Some attempts were made to develop satellite based weapons but this work was halted in 1967 following the ratification of international treaties banning the deployment of weapons of mass destruction in orbit. As of 2013, there are 950 satellites of all types in Earth orbit. It is not possible to identify the exact number of these that are military satellites partly due to secrecy and partly due to dual purpose missions such as GPS satellites that serve both civilian and military purposes. As of December 2018 there are 320 known military or dual-use satellites in the sky, half of which are owned by the US, followed by Russia, China and India (13).

RISAT-2
RISAT-2, or Radar Imaging Satellite-2 was an Indian radar imaging reconnaissance satellite that was part of India's RISAT programme. It was built by Indian Space Research Organisation (ISRO) and successfully launched aboard a PSLV-CA launch vehicle at 01:15:00 UTC on 20 April 2009 from the Second Launch Pad at the Satish Dhawan Space Centre. The principal sensor of RISAT-2 was an X-band synthetic-aperture radar (SAR) from Israel Aerospace Industries (IAI). It is designed to monitor India's borders and as part of anti-infiltration and anti-terrorist operations. The satellite has a mass of . History RISAT-2 was built at an accelerated pace following the 2008 Mumbai attacks, due to delay with the indigenously developed C-band for RISAT-1. It is India's first dedicated reconnaissance satellite. The X-band SAR used by RISAT-2 was obtained from Israel in return for launch services for the Israeli TecSAR-1 satellite. The SAR sensor enables RISAT-2 to return images at any time o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panchromatic
Panchromatic emulsion is a type of black-and-white photographic emulsion that is sensitive to all wavelengths of visible light. Description A panchromatic emulsion renders a realistic reproduction of a scene as it appears to the human eye, although with no colors. Almost all modern photographic film is panchromatic. Some older types of film were orthochromatic and were not sensitive to certain wavelengths of light. As naturally prepared, a silver halide photographic emulsion is much more sensitive to blue and UV light than to green and red wavelengths. The German chemist Hermann W. Vogel found out how to extend the sensitivity into the green, and later the orange, by adding sensitising dyes to the emulsion. By the addition of erythrosine the emulsion could be made orthochromatic while some cyanine derivatives confer sensitivity to the whole visible spectrum making it panchromatic. However, his technique was not extended to achieve a fully panchromatic film until the early 190 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology Experiment Satellite
Technology Experiment Satellite (TES) is an Indian remote sensing and photo-reconnaissance satellite. Launch TES was launched by the PSLV-C3 rocket from the Sriharikota High Altitude Range (SHAR) at Sriharikota in the south-east Indian coast at 04:53 UT on 22 October 2001. This is the fifth consecutive successful launch of the 294-tonne Polar Satellite Launch Vehicle (PSLV) rocket and the second launch with multiple satellites. The 1108 kg satellite carries a one-meter resolution panchromatic camera is an experimental satellite to demonstrate and validate, in orbit, technologies that could be used in the future satellites of Indian Space Research Organisation (ISRO). It was successfully placed in 572 km Sun-synchronous orbit on 22 October 2001 using the PSLV-C3. The PSLV-C3 also injected two more satellites: PROBA, a Belgian satellite and BIRD, a German satellite. Mission The technologies demonstrated in TES are attitude and orbit control system, high torque reacti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-satellite Weapon
Anti-satellite weapons (ASAT) are space weapons designed to incapacitate or destroy satellites for strategic or tactical purposes. Several nations possess operational ASAT systems. Although no ASAT system has been utilised in warfare, a few countries (China, India, Russia, United Kingdom and the United States) have successfully shot down their own satellites to demonstrate their ASAT capabilities in a show of force. ASATs have also been used to remove decommissioned satellites. ASAT roles include: defensive measures against an adversary's space-based and nuclear weapons, a force multiplier for a nuclear first strike, a countermeasure against an adversary's anti-ballistic missile defence (ABM), an asymmetric counter to a technologically superior adversary, and a counter-value weapon. Use of ASATs generates space debris, which can collide with other satellites and generate more space debris. A cascading multiplication of space debris could cause Earth to suffer from Ke ...

GSAT-6A
GSAT-6A was a communication satellite launched by the Indian Space Research Organisation (ISRO) It featured a unfurlable S-band antenna similar to the one used on GSAT-6. Around 17 minutes after lift-off, the three stage GSLV Mk.II rocket flying on GSLV F08 mission successfully injected the satellite into a geosynchronous transfer orbit. Due to power failure during its orbit raising burns the communication was lost with GSAT-6A before it could reach its final circular geostationary orbit (GSO). History GSAT-6A was launched to complement GSAT-6 satellite which was launched in August 2015 by ISRO. The cost of building GSAT-6A was around ₹270 crore. GSAT-6A was to provide mobile communication services to the Indian Armed Forces. Launch GSLV-F08 carrying GSAT-6A spacecraft was launched from Second Launch Pad of Satish Dhawan Space Centre on 29 March 2018, 11:26 UTC and after flight of 17 minutes 45 seconds, placed GSAT-6A into its planned geostationary transfer orbit with apog ...
