What is geostationary satellite?

A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)

How could the altitude and azimuth be important?

Altitude and azimuth are important for determining the position of celestial objects in the sky. Altitude measures the angle above the horizon, while azimuth measures the direction from north. Astronomers use these coordinates to locate and track stars, planets, and other astronomical objects. Similarly, hikers and navigators use altitude and azimuth to find their way using landmarks and the positions of the sun and stars.
