← Q3 Q5 →

What is the primary advantage of placing a satellite in a geosynchronous orbit, such as EOS-05?

A It provides high-resolution images with very short revisit times due to fast movement relative to Earth.
B It allows persistent real-time monitoring of a fixed region by matching Earth's rotational period.
C It eliminates all atmospheric drag and space debris risks completely.
D It enables direct underwater communication without acoustic transponders.

Correct answer: (b) It allows persistent real-time monitoring of a fixed region by matching Earth's rotational period.

Explanation

Option B is correct because a geosynchronous orbit matches Earth's rotational period, allowing the satellite to remain fixed above a specific longitude for persistent real-time monitoring. Option A describes LEO characteristics.
