Problem 2. Ground Tracks Revisited The ground tracks for three satellites (1,2,3) are shown in the figure. At time to the positions of the satellites in their orbits are indicated by the black squares and the First Point in Aries is located at 90 W. Assume each orbit is prograde. Orbit 1 has hinge symmetry. Orbit 2 has no symmetries. Orbit 3 has longitudinal symmetry. Answer the following questions about the orbital properties. If there is insufficient information to determine the property, write "insufficient information" In each case, justify your answer. a. What is the period of each orbit b. What is the argument of perigee of each orbit? C. What is the longitude of ascending node of each orbit? 90 N 60 N 30 N 0 30 S 60 S. 90 S-120E 150E 180E 150 W 120 W 90 W 60 W 30 W 0 30E 60E 90 E
