How do you find the height of a geostationary satellite?

1 Answer

1. A geostationary satellite is a satellite which revolves around the Earth with exact same angular speed and direction as the Earth.
2. T = 24 × 3600 s = 8.64 × 104s.
3. Let h be the height of orbit.
4. ≅ (4.24 × 107 ) – (6.4 × 106)m.
5. ≈ 3.6 × 107 m or 36,000 km from the surface of Earth.

Can we calculate height of satellite from the Earth?

The centripetal acceleration of the satellite in orbit is balanced by the gravitational force acting between the earth and the satellite. If we apply this concept, we can find the height at which the satellite is rotating about the earth. Also, we can assume that the communication satellite is in a geostationary orbit.

What is the height of geostationary satellite from the Earth?

1.2. 1 Geostationary Satellites. A geostationary satellite is in a geostationary orbit, which can only be achieved at an altitude very close to 35,786 km (22,236 m) and keeps the satellite fixed over one longitude at the equator. The satellite appears motionless at a fixed position in the sky to ground observers.

What is the height of satellite?

The height of geostationary satellite from the surface of the earth is 36000 km.

What is the height of Polar satellite?

Polar is a cylindrical satellite of 2.4 meters in diameter and 1.8 meters in height built by the “Astro Space” division of Martin Marietta.

What is the height of remote sensing satellite?

Satellites orbiting at 35,786 km are at an altitude at which their orbital speed matches the planet’s rotation, and are in what is called geosynchronous orbit (GSO).

What is the height of a synchronous satellite?

A satellite in a Sun-synchronous orbit would usually be at an altitude of between 600 to 800 km.

How does a satellite measure height?

The surface height is measured by a radar altimeter which is attached to a satellite. It emits microwaves and measures the time it takes for the waves to be reflected from the ground to return to the altimeter. For the measurement it is crucial to determine the exact position of the satellite.

What is the height of near polar orbiting remote sensing satellite Mcq?

Explanation: Polar satellites orbit close to the earth at distances of about 500 – 800 km above the surface and have time periods of about 90 – 100 minutes.

What is the height of the satellite orbiting the Earth?

Since the earth’s surface is 6.37 x 10 6 m from its center (that’s the radius of the earth), the satellite must be a height of above the surface of the earth. So the height of the satellite is 3.59 x 107 m. Investigate! There are hundreds of artificial satellites orbiting the Earth.

How do you find the height of the earth above the surface?

The radius of the Earth is 6.37*10 6 m. We can calculate the height h above the Earth’s surface by subtracting the radius of the Earth from the radius of the orbit. h = 4.22*10 7 – 6.37*10 6 = 3.583*10 7 m.

How do you find the radius of a satellite’s orbit?

Note that the radius of a satellite’s orbit can be found from the knowledge of the earth’s radius and the height of the satellite above the earth. As shown in the diagram at the right, the radius of orbit for a satellite is equal to the sum of the earth’s radius and the height above the earth.

What is a geo-stationary satellite?

A satellite placed at a definite height directly above the Earth’s equator and revolves in the same direction as the Earth rotates; so that its orbital time period is same as the Earth’s rotation period ( 24 hours), is called a Geo-stationary satellite.
