Cartosat
The Cartosat is a series of Indian optical earth observation satellites built and operated by the Indian Space Research Organisation (ISRO). The Cartosat series is a part of the Indian Remote Sensing Program. They are used for Earth's resource management, defence services and monitoring. History The Department of Space (DoS) had launched and managed the IRS series of remote sensing satellites for Earth's resource management and monitoring. These satellites were very successful in providing data in various scales ranging from 1:1 Million to 1:12,500 scale. Each of the IRS missions ensured data continuity while introducing improvements in the spatial, spectral and radiometric resolutions. Considering increased demand for large scale and topographic mapping data, the DoS launched the expanded Cartosat series of remote sensing satellites. The first satellite of the series, Cartosat-1, was launched in 2005. Satellites Cartosat-1 Cartosat-1 was launched by PSLV-C6 on 5 May ...

Both are linear transponders offering the CW, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satish Dhawan Space Centre Second Launch Pad
Satish Dhawan Space Centre - SDSC (formerly Sriharikota Range - SHAR) is a rocket launch centre (spaceport) operated by Indian Space Research Organisation (ISRO). It is located in Sriharikota, Tirupati district of Andhra Pradesh. Sriharikota Range was renamed in 2002 after ISRO's former chairman Satish Dhawan. History Sriharikota island was chosen in 1969 for a satellite launching station. The centre became operational in 1971 when an RH-125 sounding rocket was launched. The first attempted launch of an orbital satellite, Rohini 1A aboard a Satellite Launch Vehicle, took place on 10 August 1979, but due to a failure in thrust vectoring of the rocket's second stage, the satellite's orbit decayed on 19 August 1979. SHAR was named as 'Satish Dhawan Space Centre SHAR' (SDSC), on 5 September 2002, in memory of Satish Dhawan, former chairman of the ISRO. The SHAR facility now consists of two launch pads, with the second built in 2005. The second launch pad was used for launches ...

PSLV-C5
PSLV-C5 was the fifth operational launch and overall eighth mission of the Polar Satellite Launch Vehicle program. This launch was also the fifty-second launch by the Indian Space Research Organisation (IRSO) since its first mission on 1 January 1962. The vehicle carried and injected India's Earth observation satellite, remote sensing satellite Resourcesat-1 (also known as IRS-P6) into a sun-synchronous orbit; this was the heaviest and most sophisticated satellite built by IRSO through 2003. PSLV-C5 was launched at 04:52 hours Coordinated Universal Time (10:22 hours Indian Standard Time) on 17 October 2003 from Satish Dhawan Space Centre.

Newton (unit)
The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as 1 kg⋅m/s, the force which gives a mass of 1 kilogram an acceleration of 1 metre per second per second. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion. Definition A newton is defined as 1 kg⋅m/s (it is a derived unit which is defined in terms of the SI base units). One newton is therefore the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. The units "metre per second squared" can be understood as measuring a rate of change in velocity per unit of time, i.e. an increase in velocity by 1 metre per second every second. In 1946, Conférence Générale des Poids et Mesures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed to accelerate 1 kilogram of mass at the rate ...

Thrust
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called thrust. Force, and thus thrust, is measured using the International System of Units (SI) in newtons (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 meter per second per second. In mechanical engineering, force orthogonal to the main load (such as in parallel helical gears) is referred to as static thrust. Examples A fixed-wing aircraft propulsion system generates forward thrust when air is pushed in the direction opposite to flight. This can be done by different means such as the spinning blades of a propeller, the propelling jet of a jet engine, or by ejecting hot gases from a rocket ...

Vikas (rocket Engine)
The Vikas (a portmanteau from initials of ''VIK''ram ''A''mbalal ''S''arabhai ) is a family of liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre in the 1970s. The design was based on the licensed version of the Viking engine with the chemical pressurisation system. The early production Vikas engines used some imported French components which were later replaced by domestically produced equivalents. It is used in the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV) series of expendable launch vehicles for space launch use. Vikas engine is used to power the second stage of PSLV, boosters and second stage of GSLV Mark I and II and also the core stage of GSLV Mark III. The propellant loading for Vikas engine in PSLV, GSLV Mark I and II is 40 tons, while in GSLV Mark III is 55 tons. History In 1974, Societe Europeenne de Propulsion agreed to transfer Viking engine technology in return for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propellant Strap On Motor
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which is contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel are two ...
