In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit.These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon.. On 4 October 1957 the Soviet Union launched the world's first artificial satellite, Sputnik 1.Since then, about 8,900 satellites from more than 40 countries have been launched. As we described in the previous section, an object with negative total energy is gravitationally bound and therefore is in orbit. It can be shown that a more general expression for the velocity of an orbiting satellite is = − a 1 r 2 v GmE where the mass of the satellite is negligible relative to the mass of Earth. 1:32. If a satellite's orbit is perturbed, it simply goes into a slightly different orbit, possibly more or less circular than its original. derivation of orbital velocity . Finally, the eclipse intervals of satellites’ orbit are calculated. The answer is 5600 m/s but i'm not sure how to get it. If a satellite deviates significantly from its desired orbit, whether that's circular or not, they have thrusters to compensate. Using a one-tangent burn, it is to be transferred to geosynchronous altitude using a transfer ellipse with a semi-major axis of 30,000 km. Start by determining the radius of a geosynchronous orbit.
