![]() Then using L 2=m 2r max 2v 2 at apogee gives v=sqrt#. Now the first issue is whether or not I can use their approximation of R=40000km and so then assume that the elliptical orbit has the correct radial distance, just not the correct speed at apogee.Īssuming I can do that, equating the energy at apogee and perigee using dr/dt=0 and using r=r min at perigee and r=r max at apogee, I can find L 2. Any point on the equator plane revolves about. In the geostationary orbit, I have v=3076ms -1 and R=42000km. A geostationary orbit is a circular orbit directly above the Earths equator approximately 35,786 km above ground. They are the most distant satellites, at. So just what is a geostationary orbit In general terms, it is a special orbit for which any satellite in that orbit will appear to hover stationary over a point on the earths surface. Therefore, the grounds of these satellites is very limited. The orbit distance is in the plane with the equator, thus, these satellites can be sent in only one circle around the world. They reach the greatest Earth surface area. This report aims to describe the design of geostationary satellites in terms of orbital analysis. The first geosynchronous satellite was sent into orbit in 1963, and in the following year, the first geostationary satellite was sent. Where M is the mass of the Earth, m that of the satellite. Geostationary orbits (GEO) are used for tv, and communication satellites. This gives an orbital speed of 11,035 kilometers per hour. Calculate the change in velocity the motor needs to provide.Ĭonservation of angular momentum and of energy. For instance, for a geostationary orbit, the period is 24 hrs and the circumference of the orbit is 264,830 km. When it is at apogee, a brief firing of its rocket motor places it into the circular orbit. Satellites following a geostationary orbit will. The Earth which has a period of 24 hours) and show that its radius is approximatelyĪ satellite is to be inserted in to a geostationary orbit from an elliptical orbit with perigee at a geocentric radius of 8,000 km and apogee at 40,000 km. Geostationary orbit involves a satellite orbiting above the Earth's equator while its orbital period is equal to Earth's rotational period or day. Calculate the orbital velocity in a geostationary orbit (the circular orbit around ![]()
