A Guide to VSAT Connectivity Across the Mediterranean: Exploring Maritime, Urban, and Remote Applications

1/9/23 | 6 minute read

Communication technologies like VSAT (Very Small Aperture Terminal) have become vital for connecting diverse regions and cultures. Within the Mediterranean, the role of VSAT has particularly evolved, serving bustling urban centres and remote islands alike.

VSAT Definition and Core Components

VSAT stands for Very Small Aperture Terminal, referring to a type of satellite communication system that uses small satellite dishes to send and receive data. A typical VSAT network consists of a central hub, satellites in geostationary orbit, and various small terminals or dishes. Here is some further information on the various components of a VSAT network:

1. Central Hub (or Ground Station)

The central hub, also known as the ground station, is the core of the VSAT network. It is responsible for managing and controlling the entire network, including handling the communication between the various small terminals or dishes and the satellite.

Functions of the Central Hub:

Coordinating Communication: It directs the flow of information, deciding how and when each terminal communicates with the satellite.

Monitoring and Control: It ensures the proper functioning of the entire network, monitoring the performance, and making necessary adjustments to optimise the signal.

Data Processing: The hub may also handle the processing and redistribution of data, linking to terrestrial networks when needed.

2. Satellites in Geostationary Orbit

Satellites in geostationary orbit (approximately 36,000 kilometres above the Earth) are positioned to remain above a fixed point on the Earth's surface. This stationary position is what allows the VSAT network to provide constant and reliable communication.

Functions of the Satellites:

Receiving Signals: The satellites receive signals from the ground station or individual terminals, amplifying them, and sending them back to Earth.

Linking Terminals: They act as a relay point, enabling communication between terminals that may not have direct line-of-sight with each other.

Covering Specific Regions: Different satellites may cover different geographic areas, providing network coverage across vast regions, including the entire Mediterranean in some cases.

3. Small Terminals or Dishes

These are the individual user points within the network. They could be located on ships, in remote villages, at business locations, or anywhere that requires communication connectivity.

Functions of the Small Terminals:

Sending and Receiving Data: They communicate with the satellites to send and receive data. This can include voice, video, internet, or other data types.

User Interface: They act as the end-user's access point to the VSAT network, often connecting to regular communication devices like telephones, computers, or television sets.

Overall Operation

In simple terms, the VSAT network operates by:

Sending Data: A small terminal sends a data request to the satellite, which relays it to the central hub.

Processing Data: The central hub processes the request and sends the required data back to the satellite.

Receiving Data: The satellite then sends this data back to the requesting terminal.

VSAT's Importance in the Mediterranean
