What is the satellite orbiting?

A satellite orbits Earth when its speed is balanced by the pull of Earth’s gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. Satellites orbit Earth at different heights, different speeds and along different paths.

What are the four types of satellite orbits?

Types of orbit

• Geostationary orbit (GEO)
• Low Earth orbit (LEO)
• Medium Earth orbit (MEO)
• Polar orbit and Sun-synchronous orbit (SSO)
• Transfer orbits and geostationary transfer orbit (GTO)
• Lagrange points (L-points)

What is satellite slide share?

SATELLITE A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Inclined orbit The path along which satellite moves in the space around earth are called orbits.

What is the shape of orbit of satellite?

Satellites undergo an elliptical orbit around the Earth. The shape and size of ellipse can be defined by i) eccentricity ( ): degree of perturbation from the perfect circle, and ii) the semi-major angle ( ): the half distance between the perigee and apogee in the ellipse.

What is the highest orbiting satellite?

The Sun-Earth L1 point is about 1,500,000 km from Earth, making this the highest orbit.

What is a satellite technology?

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.

What is the highest satellite orbiting Earth?

At present, that is probably the Chinese Queqiao lunar relay satellite, stationed at the Earth-Moon Lagrange 2 point.

• SOHO catches the Moon crossing in front of the Earth.
• The Sun-Earth L1 point is about 1,500,000 km from Earth, making this the highest orbit.
• Gaia.
• Spektr-RG.

What are the type of orbit?

According to the height of satellites from the earth, the orbits can be classified as High Earth orbit, Medium Earth orbit, and Low Earth orbit. High Earth orbit begins about one-tenth of the way to the moon.

What are the uses of satellite?

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 causes orbit?

Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.

What are the characteristics of the orbit of a satellite?

5. • Perigee: Nearest point on the orbit of a satellite from earth. • Inclination: It is determined by the angle it makes with the equator. Characteristics of orbit are • Apogee: Farthest point on the orbit of a satellite from earth.

What are the different types of satellite orbits?

Satellite Orbits a. Synchronous orbit It lies in the equatorial plane of the earth. This orbit is most useful orbit for communication purposes. b. Polar orbit c. Inclined orbit The path along which satellite moves in the space around earth are called orbits. A Satellite can move in three types of orbits namely:- a.. b.. c.. 5.

Which is the most useful orbit for communication purposes?

Synchronous orbit It lies in the equatorial plane of the earth. This orbit is most useful orbit for communication purposes. b. Polar orbit c. Inclined orbit The path along which satellite moves in the space around earth are called orbits. A Satellite can move in three types of orbits namely:- a.. b.. c..

What is the period of a satellite’s orbit?

The period of the satellite’s orbit is E 3 EGm r 2 Gm r 2 r v 2 r T = π = π π = . Again, this is only dependent on the altitude, increasing as the orbit’s altitude increases.
