Consider the following statements regarding Geostationary orbit:
Statement I: A spacecraft in the Geostationary orbit appears to an observer on Earth to be stationary in the sky.
Statement II: Satellites in geostationary orbit (GEO) fly above Earth’s equator, moving from west to east.

Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-1
(c) Statement-I is correct but Statement-II is not correct
(d) Statement-I is not correct but Statement-II is correct

Question

Consider the following statements regarding Geostationary orbit:
Statement I: A spacecraft in the Geostationary orbit appears to an observer on Earth to be stationary in the sky.
Statement II: Satellites in geostationary orbit (GEO) fly above Earth&rsquo;s equator, moving from west to east.

Which one of the following is correct in respect of the above statements?
(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-1
(c) Statement-I is correct but Statement-II is not correct
(d) Statement-I is not correct but Statement-II is correct

ONLiNE UPSC · Accepted Answer

Statement I is correct: A satellite in geostationary orbit (GEO) has an orbital period equal to Earth's rotation (about 24 hours), making it appear fixed relative to an observer on Earth.

Statement II is correct: Geostationary satellites orbit directly above the equator in the same direction as Earth's rotation (west to east) to maintain a fixed position relative to the surface.

Statement II correctly explains Statement I, because the satellite appears stationary due to its position above the equator and movement matching Earth&rsquo;s rotation.
