Geostationarysatellites are a boon in the field of communication. Explain

Satellites in circular orbits around the earth in the equatorial plane with time period 23 hrs 56 min 4.1 sec are called geostationary satellites. Since the earth rotates with same period, the satellite appears fixed from any point on the earth and so these satellites are used for communication and weather info report.
