Polar Satellite Launch Vehicle commonly known by its abbreviation PSLV‚ is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun synchronous orbits‚ a service that was‚ until the advent of the PSLV‚ commercially viable only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO). The PSLV has launched 55 satellites / spacecrafts

How do cable and satellite TV signals get to my television? Cable TV: Cable TV companies lay wiring throughout the areas they service‚ including amplifiers to make sure signal strength is good throughout. Cable can then be easily brought into your home and connected to a cable box or directly into your TV. Satellite TV: Satellite TV companies send their signal to a satellite in space‚ which then sends it down to the dish on your roof. The dish then needs to connect to a receiver box‚ which connects
