Both satellites are launched in the tangential direction. When the satellite reaches the final altitude the rocket or booster is again fired to retain it in the geostationary orbit with the correct velocity. • Circular Geostationary orbit Figure depicts typical satellite launch procedure followed by space companies such as ISRO. Hence, a minimum two-stage rocket is necessary to launch a … Some satellites are launched to observe various geographical events in a region, others are used as spy satellites, and still more are launched by private organizations to broadcast communication signals all over the globe. Just as different seats in a theater provide different perspectives on a performance, different Earth orbits give satellites varying perspectives, each valuable for different reasons. Maintaining investments in satellite technology, Turkey took its place in space in August 1994 with satellite Turksat 1B. Geostationary satellites are launched via a temporary orbit, and placed in a slot above a particular point on the Earth's surface. The radius of Earth REis 6370 km.
