Agni-I
Agni-I (Agni ''"Fire"'') is a medium-range ballistic missile that was developed by DRDO of India in the Integrated Guided Missile Development Program. It is a single-stage missile that was developed after the Kargil War to fill the gap between the range of the Prithvi (missile)#Prithvi II, Prithvi-II missile and the range of the Agni-II. It was first launched from a road mobile launcher at Integrated Test Range (ITR), Wheeler Island, India, Wheeler Island, on 25 January 2002. Less than 75 launchers are deployed. History and development Agni-I was first tested at the Interim Test Range in Chandipur, Orissa, Chandipur at 7:17AM on 22 May 1989, and is capable of carrying a conventional payload of 1,000 kg (2,200 lb) or a nuclear weapon, nuclear warhead. Agni missiles consist of one (short range) or two multistage rocket, stages (intermediate range). These are rail and road mobile and powered by solid rocket fuel, propellants. The Agni I has a range of 700–1,200 km ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agni-II
Agni-II ( IAST: Agni, ), is the second strategic ballistic missile of Agni (missile) family envisaged to be the mainstay of the Indian missile-based strategic nuclear deterrence. The Agni-II is a medium-range ballistic missile (MRBM) with two solid fuel stages and a Post Boost Vehicle (PBV) integrated into the missile's Re-entry Vehicle (RV). The Agni's manoeuvring RV is made of a carbon-carbon composite material that is light and able to sustain high thermal stresses of re-entry, in a variety of trajectories. The Agni-IIA is a more advanced version of Agni-II, albeit with more sophisticated and lighter materials, yielding a better range and operating regime. Agni-IIA was later renamed as Agni-IV plugging the gap between Agni-II and Agni-III. While the first test of Agni-IV in December 2010 was a failure, the second test flight in November 2011 was a success Agni-II, developed as part of medium- and long-range Agni series of missile systems, has already been inducted into the Ar ...

Ring Laser Gyro
A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation. Interference between the counter-propagating beams, observed externally, results in motion of the standing wave pattern, and thus indicates rotation. Description The first experimental ring laser gyroscope was demonstrated in the US by Macek and Davis in 1963. Various organizations worldwide subsequently developed ring-laser technology further. Many tens of thousands of RLGs are operating in inertial navigation systems and have established high accuracy, with better than 0.01°/hour bias uncertainty, and mean time between failures in excess of 60,000 hours. Ring laser gyroscopes can be used as the stable elements (for one degree of freedom each) in an ine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheeler Island, India
__NOTOC__ Dr. Abdul Kalam Island, formerly known as Wheeler Island, is an island off the coast of Odisha, India, approximately east of the state capital Bhubaneswar.

Circular Error Probable
In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability) is a measure of a weapon system's precision. It is defined as the radius of a circle, centered on the mean, whose perimeter is expected to include the landing points of 50% of the rounds; said otherwise, it is the median error radius. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, 50 will fall within a circle with a radius of 100 m around their average impact point. (The distance between the target point and the average impact point is referred to as bias.) There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, and R95, which is the radius of the circle where 95% of the values would fall in. The concept of CEP also plays a role when measuring the accuracy of a position obtained by a navigati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transporter Erector Launcher
A transporter erector launcher (TEL) is a missile vehicle with an integrated tractor unit that can carry, elevate to firing position and launch one or more missiles. History Such vehicles exist for both surface-to-air missiles and surface-to-surface missiles. Early on, such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack, since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site. Usually a number of TELs and TELARs are linked to one command post vehicle (CP or CPV). They may use target information from target acquisition, designation and guidance radar (TADAGR or TAR). Transporter erector launcher and radar A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firing the surface-to-air missil ...

Agni
Agni (English: , sa, अग्नि, translit=Agni) is a Sanskrit word meaning fire and connotes the Vedic fire deity of Hinduism. He is also the guardian deity of the southeast direction and is typically found in southeast corners of Hindu temples. In the classical cosmology of the Indian religions, Agni as fire is one of the five inert impermanent elements ('' pañcabhūtá'') along with space (''ākāśa''), water (''ap''), air (''vāyu'') and earth (''pṛthvī''), the five combining to form the empirically perceived material existence (''Prakṛti''). In Vedic literature, Agni is a major and oft-invoked god along with Indra and Soma. Agni is considered the mouth of the gods and goddesses and the medium that conveys offerings to them in a ''homa'' (votive ritual). He is conceptualized in ancient Hindu texts to exist at three levels, on earth as fire, in the atmosphere as lightning, and in the sky as the sun. This triple presence accords him as the messenger between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
