Geostationary satellites are primarily used for:

Geostationary satellites mainly find application in communication because it is stationary from a particular spot on Earth. Such a static position makes the satellite suitable for the transmission of television signals and internet services along with long distance communication. Orbits are fixed to place them so that continuously the same place is covered for unbroken lines of communication. While geostationary satellites are used for weather forecasting and, to a lesser extent, navigation, the core role of geostationary satellites is for communication. They are not mainly used for space exploratory purposes due to their fixed position and function, which are optimized for Earth-based applications in lieu of interplanetary or deep-space missions.
