Ground station

A ground station is a special place on Earth where people use radio waves to talk to spacecraft and satellites in space. These stations can be on the ground or high up in the air. They send and receive messages using radio waves.

One of the key parts of a ground station is a large round antenna that looks like a big dish. This antenna helps send and receive the radio waves clearly. Ground stations can stay in one spot or move around, depending on what they need to do.

Some ground stations talk mostly to communication satellites, while others work with space stations or robots exploring space. When a spacecraft is close enough for a ground station to see it, the station can send and receive data. Sometimes, two ground stations can both talk to the same spacecraft at the same time. This helps scientists and engineers keep track of everything happening in space and make sure satellites stay working properly.

Telecommunications port

A telecommunications port, also called a teleport, is a special ground station. It helps connect satellites in space with networks on Earth, like the Internet. These ports can send and receive many types of information, such as broadcasting shows or computer programs to satellites.

In May 1984, the Dallas/Fort Worth Teleport was the first one in America to start working.

Earth terminal complexes

An Earth terminal complex is a set of tools and buildings used to connect a ground station to talk to spacecraft. This idea started with rules from the United States General Services Administration. Now, these rules are part of a bigger guide made by the Alliance for Telecommunications Industry Solutions, a group that helps businesses with communication technology. The Telecommunications Industry Association also uses this same definition.

Satellite communications standards

The ITU Radiocommunication Sector, part of the International Telecommunication Union, makes rules for how satellites and Earth stations talk to each other. These rules were created by many countries working together.

Big satellite companies also have their own rules. For example, Intelsat has rules called the Intelsat Earth Station Standards. These rules help decide what kind of equipment ground stations need to use. Eutelsat also has its own rules. There are groups that help different space agencies work together smoothly.

Networks

A network of ground stations is a group of stations that help talk to and track spacecraft. These networks support special missions or programs.

Ground station networks include:

• United States Space Force Satellite Control Network (SCN)
• NASA Near Space Network
• NASA Deep Space Network
• Russia tracking network
• European Space Tracking (ESTRACK) network
• ISRO Telemetry, Tracking and Command Network (ISTRAC)
• JAXA Near-Earth Tracking and Control Network
• China Satellite Launch and Tracking Control (CLTC)
• Norway Kongsberg Satellite Services (KSAT)
• Swedish Space Corporation (SSC) CONNECT ground station network
• RBC Signals Global Ground Station Network
• Leaf Space ground station network
• Amazon Web Services Ground Station network
• SatNOGS Network

Other historical networks have included:

• Smithsonian Astrophysical Observatory (SAO) Optical Tracking Network
• US Minitrack
• Applied Physics Laboratory Transit Network (Tranet)
• Interkosmos network
