What is VSAT and how it works?
A very small aperture terminal (VSAT) is a small-sized earth station used in the transmit/receive of data, voice and video signals over a satellite communication network, excluding broadcast television. The satellite sends and receives signals from a ground station computer that acts as a hub for the system.
What is VSAT equipment?
VSAT stands for “Very Small Aperture Terminal” and its purpose is to transmit and receive satellite transmissions. A VSAT comprises a dish antenna, a transceiver (or a combination of BUS and LNB) and a satellite router (modem). Receive-only VSAT terminal may not include a transmitter (BUC).
What are the advantages of VSAT?
➨VSAT provides same quality of service and speed at all the locations across the entire VSAT network. ➨VSAT services are independant of other wired and wireless mediums used as transmission network service provider. Hence it is a great backup system which is available during disaster and emergency situations.
What is VSAT receiver?
VSAT refers to receive or transmit terminals installed at dispersed sites connecting to a central hub via satellite using small diameter antenna dishes (0.6 to 3.8 meter). The majority of VSAT antennas range from 75 cm to 1.2 m. Section V describes VSAT transmitter & receiver part.
What is the difference between satellite and VSAT?
Technically, VSAT refers to any two-way satellite ground mounted or a stabilized maritime VSAT antenna with an antenna (dish) that is smaller than 3 meters; people generally use the term VSAT to refer to any two-way satellite Internet terminal that is not a teleport Earth Station.
Where is VSAT?
VSAT terminals are used in military and naval applications to ensure communication even in remote locations. They are also used in narrowband financial applications like point-of-sale transactions, and broadband data like Voice over Internet Protocol (VoIP), and satellite internet.
What are the types of VSAT?
- Introduction. VSAT (Very Small Aperture Terminal) consists of a terminal with very small dimensions which is able to provide bi-directional communication connectivity.
- Point-to-Point links (SCPC)
- Star Networks (TDMA)
- Point to Multi-Point (Mesh)
- Multi-Point with Multi-Point and Star.
How much does VSAT cost?
Auto-pointing VSAT systems can range in price from $20,000 to $200,000 depending upon the type of system deployed. A trained technician is required for VSAT installations, so you will have additional costs with VSAT for initial fixed site installations.
How long does VSAT last?
45 seconds
The Orbital VSAT will last for 45 seconds after it is called in. When it ends, the arrows stop moving and gradually become red dots again.
Which band is used in VSAT?
VSAT system can operate using various industry frequencies such as C-Band, Ku-Band, Ka-Band and X-Band. However, most commercial VSAT networks use the C-Band and Ku-Band frequencies. C-Band frequency range from 3.6 – 4.2 GHz for receive and 5.8 – 6.4 GHz for transmit.
Who uses a VSAT system?
Which technology is used in VSAT?
The VSAT satellite technology uses a type of antenna that receives and transmits data and that by its acronym in English means Very Small Aperture Terminal.
