What is Satellite Communication

Satellite communication involves using artificial satellites to transmit data, voice, or video signals between two or more points on Earth.

Types of Satellite Communication

1. Geostationary Satellites: Orbit at 36,000 km above the equator, providing continuous coverage of a specific region.
2. Medium Earth Orbit (MEO) Satellites: Orbit at 2,000-36,000 km above the equator, providing wider coverage and faster data transfer.
3. Low Earth Orbit (LEO) Satellites: Orbit at 160-2,000 km above the equator, providing high-speed data transfer and low latency.
4. Polar-Orbiting Satellites: Orbit at 800-1,000 km above the Earth's surface, providing coverage of polar regions.

Satellite Communication Process

• Uplinking: Transmitting data from a ground station to a satellite.
• Transponding: Receiving data by the satellite and retransmitting it to another location.
• Downlinking: Receiving data by a ground station from a satellite.

Application of Satellite Communication

• Telecommunications: Voice and data transmission, mobile networks.
• Broadcasting: Television, radio, and multimedia services.
• Navigation: GPS, location-based services.
• Remote Sensing: Earth observation, weather forecasting, environmental monitoring.
• Emergency Response: Search and rescue, disaster relief.
