Modern Satellites System

 1.Types Of Satellites:

Different Orbits & Real-World Uses Throughout the years, different types of satellites have become indispensable, supporting diverse activities ranging from broadcasting and navigation to remote sensing of the planet. They serve a variety of purposes, so it’s common to classify them depending on their functions. Several types of satellites’ orbits, each with its own unique set of characteristics, are used for different missions. At the same time, all of the different satellite types, no matter what they’re used for, help us learn more about the planet, connect people in far-flung places, mitigate human-caused and natural disasters, and open up new technological possibilities for humanity.

2.    What Was the First Satellite in Space?

Sputnik 1 was the first satellite in space. The Soviet Union launched it in 1957.October1957 - Sputnik Launched Sputnik 1

3. What Is the History of NASA Satellites?

NASA has launched dozens of satellites into space, starting with the Explorer 1 satellite in 1958. Explorer 1 was America’s first man-made satellite. The main instrument aboard was a sensor that measured high-energy particles in space called cosmic rays.

The first satellite picture of Earth came from NASA’s Explorer 6 in 1959. TIROS-1 followed in 1960 with the first TV picture of Earth from space. These pictures did not show much detail. But they did show the potential satellites had to change how people view Earth and space.

4. How Does NASA Use Satellites Today?

NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke .All this information helps scientists predict weather and climate.

 The information also helps public health officials track disease and famine; it helps farmers know what crops to plant; and it helps emergency workers respond to natural disasters.Satellites that face toward space have a variety of jobs. Some watch for dangerous rays coming from the sun. Others explore asteroids and comets, the history of stars, and the origin of planets. Some satellites fly near or orbit other planets. These spacecraft may look for evidence of water on Mars or capture close-up pictures of Saturn’s rings.

5.How satellites work

A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder—an integrated receiver and transmitter of radio signals. A satellite has to withstand the shock of being accelerated during launch up to the orbital velocity of 28,100 km (17,500 miles) an hour and a hostile space environment where it can be subject to radiation and extreme temperatures for its projected operational life, which can last up to 20 years.

In addition, satellites have to be light, as the cost of launching a satellite is quite expensive and based on weight. To meet these challenges, satellites must be small and made of lightweight and durable materials. They must operate at a very high reliability of more than 99.9 percent in the vacuum of space with no prospect of maintenance or repair.Communication satellites range from microsatellites weighing less than 1 kg (2.2 pounds) to large satellites weighing over 6,500 kg (14,000 pounds). Advances in miniaturization and digitalization have substantially increased the capacity of satellites over the years. Early Bird had just one transponder capable of sending just one TV channel. The Boeing 702 series of satellites, in contrast, can have more than 100 transponders, and with the use of digital compression technology each transponder can have up to 16 channels, providing more than 1,600 TV channels through one satellite

.Satellites operate in three different orbits: low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary or geosynchronous orbit (GEO). LEO satellites are positioned at an altitude between 160 km and 1,600 km (100 and 1,000 miles) above Earth. MEO satellites operate from 10,000 to 20,000 km (6,300 to 12,500 miles) from Earth. (Satellites do not operate between LEO and MEO because of the inhospitable environment for electronic components in that area, which is caused by the Van Allen radiation belt.) GEO satellites are positioned 35,786 km (22,236 miles) above Earth, where they complete one orbit in 24 hours and thus remain fixed over one spot. As mentioned above, it only takes three GEO satellites to provide global coverage, while it takes 20 or more satellites to cover the entire Earth from LEO and 10 or more in MEO. In addition, communicating with satellites in LEO and MEO requires tracking antennas on the ground to ensure seamless connection between satellites.

6. Communications Act of 1934

Communications Act of 1934, U.S. federal law that provided the foundation for contemporary U.S. telecommunications policy. The Communication Act of 1934 established the Federal Communications Commission (FCC), an independent U.S. agency responsible for the regulation of interstate and foreign communications by radio, television, wire, and, later, satellite.

 The 1934 act built upon the Radio Act of 1927, which was a temporary measure when it was passed, intended to stabilize the burgeoning but chaotic radio industry of the mid-1920s. The 1934 act added communications via common carrier and television

8.  Who controls the Internet?

While the Internet is theoretically decentralized and thus controlled by no single entity, many argue that tech companies such as Amazon, Facebook, and Google represent a small concentration of organizations that have unprecedented influence over the information and money on the Internet. In some countries, certain parts of the Internet are blocked via censorship.

9.   Why Are Satellites Important?

The bird’s-eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground.Satellites also can see into space better than telescopes at Earth’s surface. That’s because satellites fly above the clouds, dust and molecules in the atmosphere that can block the view from ground level.Before satellites, TV signals didn’t go very far. TV signals only travel in straight lines. So they would quickly trail off into space instead of following Earth’s curve.

 Sometimes mountains or tall buildings would block them. Phone calls to faraway places were also a problem. Setting up telephone wires over long distances or underwater is difficult and costs a lot.With satellites, TV signals and phone calls are sent upward to a satellite. Then, almost instantly, the satellite can send them back down to different locations on Earth.

10. How Konnect Improves Satellite Internet Speeds?

The technicians at Konnect know how to boost your satellite Internet signal for optimal service. There are some technicalities to this, but the theory is very simple to understand. Your satellite dish will work best if it is pointing directly towards the satellite that's providing the service.

 Therefore, when it is installed for you, careful checks are made to ensure it is correctly lined up and the signal is strong.Your satellite dish should not just point directly at the satellite serving it. It should also have an uninterrupted line of sight. So, if you have put a ladder in the way of it or a shrub has grown in front of it, then it will be a good idea to remove them. Sometimes snow may settle on a satellite dish, too. If this is the case, then the signal levels may drop so it’s best to brush off accumulated snow, being careful not to knock the dish out of its alignment.
