What determines the orbit of the satellite?

What determines the orbit of the satellite?

The height of the orbit, or distance between the satellite and Earth’s surface, determines how quickly the satellite moves around the Earth. An Earth-orbiting satellite’s motion is mostly controlled by Earth’s gravity. Changing a satellite’s height will also change its orbital speed.

What two things determine the orbit of a satellite explain?

So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits.

What are the main features of a satellite?

The main components of a satellite consist of the communications system, which includes the antennas and transponders that receive and retransmit signals, the power system, which includes the solar panels that provide power, and the propulsion system, which includes the rockets that propel the satellite.

What is the purpose of launching satellite?

Satellites are used for many purposes. Among several other applications, they can be used to make star maps and maps of planetary surfaces, and also take pictures of planets they are launched into.

On what factors orbital speed of a satellite depends?

The orbital speed of the satellite depends on its altitude above the Earth. To maintain an orbit that is 35,786 km above the Earth, a satellite must orbit at the speed of about 11,300 km per hour. That orbital speed and distance permit the satellite to make one revolution in exactly 24 hours.

What determines a planet’s orbital period?

A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.

What do you know about orbit?

An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Most of the objects orbiting the sun move along or close to an imaginary flat surface.

What is the principle of launching an artificial satellite?

Answer: The principle is two-fold: >> First, a rocket launches the satellite to an altitude where it will operate. >> Second, the rocket gives the satellite enough speed where, instead of falling back to Earth, it falls around Earth.

What are three functions of satellites?

What Are Satellites Used For?

  • Television. Satellites send television signals directly to homes, but they also are the backbone of cable and network TV.
  • Telephones.
  • Navigation.
  • Business & finance.
  • Weather.
  • Climate & environmental monitoring.
  • Safety.
  • Land stewardship.

What do you know about satellites?

A satellite is a moon, planet or machine that orbits a planet or star. Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space. Earth and the moon are examples of natural satellites. Thousands of artificial, or man-made, satellites orbit Earth.

How does orbital velocity of a satellite depends on the mass of the satellite?

Yes, the speed of a satellite does depend on the mass of the Earth. The total amount of (net) work done by gravity as a satellite makes a complete orbit is zero. The gravitational force has a component in the direction of the satellite’s motion as the satellite moves toward the Sun (or Earth, or whatever).

What are the factors affecting the orbital velocity of a satellite?

Factors affecting the orbital velocity of a satellite. The planet mass : The orbital velocity of a satellite is directly proportional to square root of the mass of the planet at constant radius of the orbit . The orbit radius : Orbital velocity of a satellite is inversely proportional to the square root of the orbit radius .

What is the process of launching a satellite?

The process of placing the satellite in a proper orbit is known as launching process. During this process, from earth stations we can control the operation of satellite. Mainly, there are four stages in launching a satellite.

Why do satellites need a rocket to orbit the Earth?

As the mass of the satellite increases , a rocket of greater thrust is required to launch it into space and acquire the required velocity to orbit the Earth .

What is the difference between low Earth orbit and Geosynchronous satellites?

Low earth orbit (LEO) satellites are closest to users (300-1200 miles) but require 40-70 satellites for full coverage. Low latency (10 ms). Geosynchronous (GSO) satellite orbit (22,236 miles) rotates at the same speed as the Earth’s rotation.
