2. Satellite:
Satellite Internet is the ability to transmit and receive data from a relatively small
satellite dish on Earth and communicate with an orbiting geostationary satellite
22,300 miles above Earth's equator. The orbiting satellite transmits (and receives)
its information to a location on Earth called the Network Operations Center or
NOC. The NOC itself is connected to the Internet, so all communication made
from a satellite dish to the orbiting satellite will flow through the NOC before it
reached the Internet.
Satellite internet work:
Satellite internet works by using radio waves to communicate with satellites
orbiting the Earth. Data is sent and retrieved through a communication network
that starts with your device and travels through your modem and satellite dish, out
to a satellite in space, then back to Earth to ground stations known as network
operations centers (NOC). And then, data travels back through this network—out
to space and then back to your satellite dish on Earth—to deliver data on your
device.

3. Geostationary Satellite:
There is a location in space where you can place a satellite in orbit so that from the
ground, the satellite appears stationary. What is happening is that the satellite is
actually orbiting the Earth at the same speed the Earth is rotating. The satellite
makes a complete orbit around the Earth in 24 hours, or exactly one day.
Geostationary satellites are only located at 22,300 miles directly above the Earth's
equator and nowhere else.
Applications:
Satellite internet uses a five-part relay system:
1. Internet-ready device
2. Modem/router
3. Satellite dish
4. Satellite in space
5. Network Operations Center (NOC)
6. Exploration of the solar system
7. Spacecraft have been sent to explore the space
8. Global positioning system
9. Weather satellites
10.Studying the universe
11.Navigation.
12.Climate & environmental monitoring
13.Safety. ...
14.Land stewardship.
