What are geostationary satellites used for.

A large geostationary satellite can provide a large amount of capacity across up to a third of the earth s surface and a network can cover the earth with only three satellites. A worldwide network of operational geostationary meteorological satellites is used to provide visible and infrared images of earth s surface and atmosphere for weather observation oceanography and atmospheric tracking as of 2019 there are 19 satellites in either operation or stand by. Geostationary orbit is that particular orbit where the orbital period of a satellite is equal to that of earth 24 hrs. The national oceanic and atmospheric administration noaa operates two sets of satellites to monitor the weather.

The satellites are positioned 22 300 miles above the earth s surface in. Geostationary satellites are in a geostationary orbit around the planet s equator at an altitude of approximately 22 236 miles above sea level and they travel at 1 91 miles per second in the same direction the earth is turning. This delay is the reason why many long distance links use cables rather than satellites as the delays incurred are far less. Due to this the position of earth and satellite is always fixed.

A spacecraft in this orbit appears to an observer on earth to be stationary in the sky. The united states goes series operated by noaa. This particular orbit is. While the geostationary orbit is widely used for many satellite applications it is not suitable for all situations.

Geostationary orbit a circular orbit 35 785 km 22 236 miles above earth s equator in which a satellite s orbital period is equal to earth s rotation period of 23 hours and 56 minutes. Geostationary satellites are in orbit 22 000 miles above the equator spin at the same rate of the earth and constantly focus on the same area. These satellite systems include. In inmarsat s case this is enhanced because we have more than three satellites for each of our l band and global xpress ka band networks allowing us to layer this.

A geostationary satellite is an earth orbiting satellite placed at an altitude of approximately 35 800 kilometers 22 300 miles directly over the equator that revolves in the same direction the earth rotates west to east at this altitude one orbit takes 24 hours the same length of time as the earth requires to rotate once on its axis. The goes satellites circle the earth in a geostationary orbit above the equator which means that they hover continuously over one place on the earth s surface. This orbit is a popular choice for communication satellites operators and their users because when looking from the. This allows them to collect a continuous stream of data for one location so that movies of the data can be made.

This enables the satellite to take a picture of the earth at the same location every 30 minutes. Advantages and disadvantages of geostationary orbit satellites.
