Satellite systems are essential components of modern communication and navigation. They consist of a network of satellites that orbit the Earth, providing services such as GPS, television broadcasting, and internet connectivity. These systems enable global communication and data transfer, making them vital for both personal and commercial use. In addition to communication, satellite systems play a crucial role in monitoring the Earth's environment. Earth observation satellites collect data on weather patterns, natural disasters, and climate change, helping scientists and policymakers make informed decisions. Overall, satellite systems enhance our understanding of the planet and improve our daily lives.
