what is the principal of launching of satellite |
| Answer» The fundamental\xa0principle\xa0to be understood concerning\xa0satellites\xa0is that a\xa0satellite\xa0is a projectile. That is to say, a\xa0satellite\xa0is an object upon which the only force is gravity. Once\xa0launched\xa0into orbit, the only force governing the motion of a\xa0satellite\xa0is the force of gravity.\xa0Satellites are launched by taking them outside atmosphere, where atmospheric drag is negligible and giving them required velocity. This is usually done by rockets. Once in space, outside atmosphere, the spacecraft’s fuel is used to position the satellite in correct orbit and location. | |
