How satellites are used in space?

Satellites are used in space for a variety of purposes, including communication, navigation, weather monitoring, and Earth observation. Communication satellites facilitate global telecommunication by transmitting signals for phone, television, and internet services. Navigation satellites, such as those in the GPS constellation, provide precise location and timing information for various applications. Additionally, Earth observation satellites collect data on climate change, natural disasters, and land use, aiding in scientific research and disaster response efforts.
