Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is true about non-geostationary satellites?
A
Its orbital period around the earth is one day.
B
It is at a height of (35000-36000) km above the equator of surface of the earth.
C
Example of the satellites are GPS.
D
It can be in an orbit of which is very close to the surface of the earther or very further away from the surface of the earth.
E
Example of the satellites are communication satellites.
Explanation: 

Detailed explanation-1: -It pretends to be stationary with respect to the Earth but if we talk about the Angular Speeds of both the Earth and the Geostationary satellite, they are different. Hence, the correct option is B. Hope that this answer helps you.

Detailed explanation-2: -The satellite which appears stationary relative to earth is called the geostationary satellite . it revolves around the earth in the west-east direction with the same angular velocity as done by the earth about its own axis in the west-east direction .

Detailed explanation-3: -Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales.

Detailed explanation-4: -Non-geostationary (NGSO) satellites occupy a range of orbital positions (LEO satellites are located between 700km-1, 500km from the Earth, MEO satellites are located at 10, 000km from the Earth), and do not maintain a stationary position, but instead move in relation to the Earth’s surface.

Detailed explanation-5: -Geostationary orbit (GEO) This makes satellites in GEO appear to be ‘stationary’ over a fixed position. In order to perfectly match Earth’s rotation, the speed of GEO satellites should be about 3 km per second at an altitude of 35 786 km. This is much farther from Earth’s surface compared to many satellites.
