ST9CombinedDemo:
% Demonstrate combined simulation for a sail in ST9 orbit.
This is a dawn-dusk sun-synchronous orbit that keeps the sail illuminated at
all times. The sail is initialized along the LVLH frame.
Shows the torque produced when sail is pointed along velocity vector.
This can be avoided by aligning the sail along LVLH with a small
loss in orbit change produced per orbit. You can also test
sun-pointing and edge-on attitudes.
The gravity model includes J2 for sun-synch orbit precession.
The integration takes about 20 seconds/simulated day on a MacBook.
Since version 7.
