Q. Which of the following statements with respect to Sun-synchronous is/are correct?
Select the correct answer using the code below:
The correct option is B 2 only
Explanation:
Statement 1 is incorrect: Satellites in geostationary orbit (GEO) circle Earth above the equator from west to east following Earth’s rotation by travelling at exactly the same rate as Earth. This makes satellites in GEO appear to be ‘stationary’ over a fixed position.
Statement 2 is correct: A satellite in a sun-synchronous orbit would usually be at an altitude of 600 to 800 km. When a satellite has a sun-synchronous orbit, it means that it has a constant sun illumination through inclination and altitude. For sun-synchronous orbits, it passes over any given point on Earth’s surface at the same local solar time. Because of the consistent lighting in sun-synchronous orbits, scientists leverage this in various remote sensing applications.
