Agni-I
Agni-I () is a short-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-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, 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 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 warhead. Agni missiles consist of one (short range) or two stages (intermediate range). These are rail and road mobile and powered by solid propellants. The Agni I has a range of 700–1,200 km. They are claimed to be a part of the " Minimum credible deterrence". Agni-I is a single stage, solid fuel, road and rail mobile, ...

Agni-II
Agni-II (), is the second strategic ballistic missile of the Agni 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 Armed Forces.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circular Error Probable
Circular error probable (CEP),Circular Error Probable (CEP), Air Force Operational Test and Evaluation Center Technical Paper 6, Ver 2, July 1987, p. 1 also circular error probability or circle of equal probability, is a measure of a weapon system's Accuracy and precision, precision in the military science of ballistics. It is defined as the radius of a circle, centered on the aimpoint, that is expected to enclose the landing points of 50% of the Round (firearms), rounds; said otherwise, it is the median error radius, which is a 50% confidence interval. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, an average of 50 will fall within a circle with a radius of 100 m about that point. There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, a form of the standard deviation. Another is the R95, which is the radius of the circle ... [...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 transport, elevate to a firing position and launch one or more rockets or 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 (TELAR) A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firi ...

Agni
Agni ( ) is the Deva (Hinduism), Hindu god of fire. As the Guardians of the directions#Aṣṭa-Dikpāla ("Guardians of Eight Directions"), guardian deity of the southeast direction, he is typically found in southeast corners of Hindu temples. In the Hindu cosmology, classical cosmology of Hinduism, fire (''Agni'') is one of the five inert impermanent elements (''Pancha Bhuta, Pañcabhūtá'') along with sky (''Ākāśa''), water (''Apas''), air (''Vāyu'') and earth (''Pṛthvī''), the five combining to form the empirically perceived material existence (''Prakṛti''). In the Vedas, Agni is a major and most invoked god along with Indra and Soma (deity), Soma. Agni is considered the mouth of the gods and goddesses and the medium that conveys offerings to them in a ''homa (ritual), 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 ...
