Traffic control for jammed orbit

Space is unimaginably huge, but the stationary satellite orbit is becoming more crowded due to the communication satellite’s technological developments and because the number of satellite keeps increasing. There is only one orbit for the geostationary satellite in nature's scheme, so the demand for a totally new technology to control the satellite jam has increased. Our group is trying to determine the exact location of each satellite through the use of radio and optical techniques to plot the movement of each satellite in order to control those satellites already in the crowded orbit.


When you hear about geostationary satellites, you might imagine that they don’t move; however, they are actually in a state of constant movement in space. The reason they are called geostationary satellites is because they look like they remain in the same place in the sky since they travel around the earth at the same speed as the earth’s rotation. In reality, satellite movement is affected in various ways by the sun and moon.
