Two basic questions about satellite communication

In summary, satellite communication is the use of orbiting satellites to transmit information without the need for physical connections. It involves ground stations, satellites, and receivers, and offers benefits such as global coverage, high bandwidth, and accessibility to remote areas. The two basic questions about satellite communication are "What is satellite communication?" and "How does satellite communication work?". Challenges include high costs, vulnerability to space debris and weather, signal delays, and regulatory issues.

Hi,

1. Is it correct that gateway stations (or teleports?) must be used for spot beam satellite systems? That means, two user terminals cannot communicate directly with each other.

2. Are satellite beacons widely used?

I'm not aware of operational systems where user terminals can communicate directly with each other via satellite, but the upcoming satellite internet constellations (here is a thread) plan this.
 

FAQ: Two basic questions about satellite communication

What is satellite communication?

Satellite communication is a method of transmitting information from one location to another using satellites orbiting the Earth. This type of communication allows for long-distance and global communication without the need for physical infrastructure, such as cables or wires.

How does satellite communication work?

Satellite communication works by using a network of satellites orbiting the Earth to receive and transmit signals. The process involves the transmission of a signal from a ground station to a satellite, which then amplifies and retransmits the signal to another ground station. This allows for the signal to travel long distances and reach areas where traditional communication methods may not be available.

What are the advantages of satellite communication?

There are several advantages of satellite communication, including its ability to provide global coverage, its reliability, and its flexibility. Satellite communication can also transmit large amounts of data quickly and is not affected by natural disasters or physical obstacles on the ground.

What are the two basic questions about satellite communication?

The two basic questions about satellite communication are: "What is satellite communication?" and "How does satellite communication work?" These questions cover the fundamental concepts and processes of satellite communication.

What are the applications of satellite communication?

Satellite communication has a wide range of applications, including television and radio broadcasting, internet connectivity, navigation systems, weather forecasting, and military and government communication. It is also used in remote sensing for environmental monitoring, disaster management, and scientific research.
