Satellite communication technologies
help to track the ships and cargo through the globe
. VSAT terminals are communication terminals that allow transmitting and receiving text, audio, and video data using satellite broadband Internet services. These terminals operate as geostationary satellites on Ku, Ka, and C bands.
What are the 3 types of satellite communication?
There are three types of communication services that satellites provide:
telecommunications, broadcasting, and data communications
.
What is maritime communication?
Marine communication involves
ship-to-ship and ship-to-shore communication
. … Back in the day, semaphores and flags were a primary form of communication for ships out at sea. Radio brought about drastic changes in marine communication, and greatly improved the safety of everyone involved.
What is satellite communication simple definition?
Satellite communication, in telecommunications,
the use of artificial satellites to provide communication links between various points on Earth
. … A typical satellite link involves the transmission or uplinking of a signal from an Earth station to a satellite.

What are the two main types of communication?
Communication can be categorized into three basic types: (1)
verbal communication
, in which you listen to a person to understand their meaning; (2) written communication, in which you read their meaning; and (3) nonverbal communication, in which you observe a person and infer meaning.
Why is maritime communication important?
With ship traffic increasing around the world, it has become ever more important to improve safety and security and to safeguard our environment. When critical decisions have to be made quickly to protect or enhance any of these factors,
good communication between all involved
in the maritime chain is essential.
How does a satellite communication work?
Satellites communicate
by using radio waves to send signals to the antennas on the Earth
. The antennas then capture those signals and process the information coming from those signals. … the health of the satellite, and. where the satellite is currently located in space.
What are the most common types of satellites?
Common types include
military and civilian Earth observation satellites
, communications satellites, navigation satellites, weather satellites, and space telescopes.
What is the working principle of satellite?
The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object upon which the only force is
gravity
. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity.
