How satellites work. A satellite is basically a self-contained communications system wi e ability to receive signals from Ear and to retransmit ose signals back wi e use of a transponder—an integrated receiver and transmitter of radio signals. A satellite has to wi stand e shock of being accelerated during launch up to e orbital velocity of 28, 0 km (17,500 miles) an hour. e following statements refer to man-made, artificial satellites in orbit around ear. Which is an accurate statement? A satellite in a large diameter circular orbit will always have a longer period of revolution about e ear an will a satellite in a smaller circular orbit. As of April , ere are 2,666 operational, human-made satellites orbiting Ear. ere are also inoperative satellites, including Vanguard 1, e oldest satellite currently in orbit, and over 16,000 pieces of tracked space debris. Ear 's largest artificial satellite is e International Space Station. 28, · So if we wanted to put a satellite in a circular orbit at 500 km above e surface (what scientists would call a Low Ear Orbit LEO), it would need a speed of ((6.67 x -11 * 6.0 x 24. e altitude of e orbit is inversely related to e orbital period. e higher e satellite, e longer e orbit. Low Ear Orbit satellites, or LEO for short, orbit in about 90 minutes. Satellites. A satellite is any ing at orbits a celestial body (star, planet, moon etc). Bo natural and artificial satellites exist. Natural satellites. e Moon is e Ear ’s natural. At a distance of 36,000 km, e orbiting time is 24 hours, corresponding to e Ear 's rotation time. At is distance, a satellite above e Equator will be stationary in relation to e Ear. e Geostationary Orbit. e geostationary orbit of 36,000 km from e Ear 's Equator is best known for its many satellites which are used for. 06, · Many communications satellites and navigation satellites (GPS) are in ei er an MEO (Medium Ear Orbit = 2000km - 35,700 KM), or GEO (Geostationary Ear . Feb 24, · On e o er hand, e artificial satellites also exist which are man-made and launched from e ear. ese satellite perform certain specific functions. e first artificial satellite was. 06, · In order for geostationary satellites to keep pace wi Ear, ey must orbit at a greater distance from it (an altitude of 22,236 miles (35,786 km) to be exact). And at is increased distance, bo image detail and views of e poles (due to Ear ’s curvature) are lost. 31, · e ratio between e area of e ear and e area of e largest satellites, or 127 million km 2 to 4.09x -5 km 2, is staggeringly large. If we were to compare is ratio to e size of a 5'11/180cm tall person, we'd be asking why we couldn't see e nucleus of an atom placed next to our example human.
