Q1. With reference to Earth-observation satellites, which one of the following best explains the significance of placing EOS-05 in a higher geosynchronous orbit?

A. It enables the satellite to remain permanently above the same point on Earth and thereby provide continuous observation of a large region.

B. It allows the satellite to orbit much closer to Earth, thereby producing higher-resolution images of small areas.

C. It eliminates the need for repeated imaging because a geosynchronous satellite can observe the entire Earth simultaneously.

D. It enables the satellite to avoid atmospheric drag completely and therefore remain in orbit indefinitely.

Answer: A

Explanation: A geosynchronous orbit has a much longer orbital period than LEO and can provide frequent observation of a broad region. A geostationary orbit is the special case in which the satellite appears fixed over one point on the equator. The question tests the distinction between LEO-based Earth observation and higher geosynchronous-orbit applications.
