1. Communication Satellites: These satellites relay signals for television, telephone, radio, and internet services. They are placed in geostationary orbit, approximately 35,786 kilometers above the Earth's equator, to provide continuous coverage of a specific area.
2. Navigation Satellites: These satellites are used for positioning and timing services. The Global Positioning System (GPS) is a well-known example, consisting of a constellation of satellites that provide location and time information to users worldwide.
3. Earth Observation Satellites: These satellites capture images and data about the Earth's surface, atmosphere, and oceans. They are used for weather forecasting, environmental monitoring, and mapping.
4. Scientific Satellites: These satellites are used to conduct scientific experiments and research in various fields, such as astronomy, astrophysics, and Earth science.
5. Military Satellites: These satellites are used for military purposes, including reconnaissance, communication, and navigation. They are often placed in highly secure orbits to prevent interference or interception.
1. Low Earth Orbit (LEO): Satellites in LEO are typically between 160 and 2,000 kilometers above the Earth's surface. They are used for communication, Earth observation, and scientific research.
2. Medium Earth Orbit (MEO): Satellites in MEO are located between 2,000 and 35,786 kilometers above the Earth's surface. They are used for navigation and communication.
3. Geostationary Orbit (GEO): Satellites in GEO are located approximately 35,786 kilometers above the Earth's equator. They are used for communication and weather forecasting.
