What are geostationary satellites used for.

This orbit is a popular choice for communication satellites operators and their users because when looking from the. The geostationary satellites geostationary operational environmental satellites goes and low earth orbit satellites. While the geostationary orbit is widely used for many satellite applications it is not suitable for all situations. This allows them to collect a continuous stream of data for one location so that movies of the data can be made.

This particular orbit is. 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 delay is the reason why many long distance links use cables rather than satellites as the delays incurred are far less. 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 satellites orbit around the earth at the same rate as the earth rotates so that the satellites are over the same spot on earth all the time. 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. Due to this the position of earth and satellite is always fixed. 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.

This enables the satellite to take a picture of the earth at the same location every 30 minutes. The satellite is always present over a particular region on. 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. 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.

The national oceanic and atmospheric administration noaa operates two sets of satellites to monitor the weather. 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. 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. Computer processing of this data creates movie loops of the data that forecasters use as their.

Advantages and disadvantages of geostationary orbit satellites. Geostationary orbit is that particular orbit where the orbital period of a satellite is equal to that of earth 24 hrs.
