Problem 3. J2 Effects. In this problem we consider sun-synchronous orbits, which can be achieved by exploiting the progression of the longitude of nodes. a. Determine the inclination i for a circular sun-synchronous orbit with a 1.5 hour period. b. At the vernal (spring) equinox, the longitude of ascending nodes of the orbit from (a) is given by = 90. What is . at the summer solstice? c. When looking directly down from the satellite to the surface of the earth, what is the approximate local time it will see (noon/midnight, dusk/dawn, afternoon/morning, etc.) at A = 0 and A = 25N. orbit is attractive for solar powered spacecraft. Explain why this type of
