Which of the following is correct regarding medium earth orbit?
I. Satellites in MEO do not need to follow specific paths around Earth.
II. MEO is very commonly used by navigation satellites.
Show answer & explanation
Correct answer: C
Explanation
- Medium Earth orbit is located between approximately 2000 and 35,000 km above Earth.
- Satellites in this orbit orbit the Earth in fixed paths.
- Therefore, the first statement, that satellites do not have to follow a specific path, is incorrect.
- In fact, every satellite has to follow its fixed orbit.
- The second statement is correct because MEO is widely used by navigation satellites.
- Systems like GPS, GLONASS, and Galileo operate in this orbit.
- Therefore, the correct answer is both I and II.
