How do ground stations communicate with satellites?
Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link.

What is the purpose of VSAT?
What is VSAT and its advantages?
A VSAT (Very Small Aperture Terminal), also known as a micro-terminal, refers to a wide range of remote terminals that are small in size but which nevertheless allow access to a larger data network. A VSAT allows users to access and manage data in real time and comes with many applications in finance.
Why VSAT is used?
A very small aperture terminal (VSAT) is a data transmission technology used for many types of data management and in high-frequency trading. VSAT can be used in place of a large physical network as it bounces the signal from satellites instead of being transported through physical means like an ethernet connection.
