Both PSLV (Polar Satellite Launch Vehicle) and GSLV are (Geosynchronous Satellite Launch Vehicle) are launch Indian vehicles used to launch satellites into polar orbit and geosyncronous orbits respectively. The PSLV can launch satellites into sun synchronous orbits i. e. in such a way that an object on that orbit passes over any given point of the Earth's surface at the same local solar time. The GSLV launch satellites into geostationary orbit. Geostationary orbits cause a satellite to appear stationary with respect to a fixed point on the rotating Earth. That is, if you were standing directly below a geosyncronous satellite it would always be directly above you. The PSLV is a four-stage launch vehicle with the first stage being solid-propelled, the second liquid-propelled and third solid and the final stage cryogenic liquid. It required parts obtained from Russia. The GSLV is a three-stage launch vehicle with the first stage being solid-propelled, the second liquid-propelled and the final stage being cryogenically propelled. It was developed by India partly to free itself from dependence on Russia.

Explain how the remote sensing satellites examined the earth from the space?
Lots of ways. For example, the momentum of satellite + meteor before the impact, is the same after the impact.
Rockets primarily are used to launch satellites into space. Alternatively, the space shuttle is used for very large satellites, but that option will no longer be available when the fleet is retired at the end of 2010.

satellite launch vehicle ( ROCKET)
India has two space rockets capable of launching satellites and space probes. The Polar Satellite Launch Vehicle (PSLV) and the Geosynchrounous Satellite Launch Vehicle (GSLV). Given the Payload mass of 1,308 kilograms of Chandrayaan-1, the PSLV was adequate to launch the Chandrayaan-1 into Earth orbit prior to commencing it's journey to the Moon. The Geosynchronous Satellite Launch Vehicle (GSLV) is a newer generation satellite launch vehicle capable of putting into Geostationary Earth orbit much heavier payloads up to 2500 kg.

For the Indian rocket, see Satellite Launch VehicleA Saturn V launch vehicle sends Apollo 15 on its way to the moon.In spaceflight, a launch vehicle or carrier rocketis a rocket used to carry a payload from the Earth's surface into outer space. A launch system includes the launch vehicle, the launch pad and other infrastructure.[1] Usually the payload is an artificial satellite placed into orbit, but some spaceflights are sub-orbital while others enable spacecraft to escape Earth orbit entirely. A launch vehicle which carries its payload on a suborbital trajectory is often called a sounding rocket
The full form of GSLV is Geosynchronous Satellite Launch Vehicle. It is an expendable launch vehicle used by the Indian Space Research Organization (ISRO) to launch satellites into geosynchronous transfer orbit.
Rockets are used as engines to accelerate the satellite to a speed fast enough to get it in orbit.

The cost varies depending on the size of the satellite, which determines which launch vehicle (rocket) can be used, the orbit the satellite is to put into (polar, low Earth orbit, geosynchronous, etc.) Costs start at about $50 million which does not include the cost of developing and building the satellite.
A trajectory is the path a rocket takes, it is not a thing that can be dropped. Further rockets are used to "launch" a satellite into orbit, not drop it (so that it falls back to Earth).
Generally space shuttles are not used to launch satellites as it is very costly to launch a space shuttle. Rockets with automated systems place satellites in orbit as opposed to a manned shuttle.
Normally satellites are placed on top of rockets and carried into space, then they are released/pushed out of the rocket once it reaches space. It is first pushed out (injected) into an orbit close to earth called a "transfer orbit," meaning an orbit used to move it from the release location to the primary/intended orbit. Sometimes a booster motor is used to move it into the transfer orbit. After the transfer orbit moves it to the correct location another motor changes it's direction/motion into the final/primary orbit. Sometimes a satellite is carried into space by the Space Shuttle, and then released. After that it moves into a transfer orbit that carries it to the final orbit like other satellites.
