BEGIN_DESC
Molniya orbits are highly eccentric Earth orbits with periods of approximately 12 hours (2 revolutions per day).
The orbital inclination is chosen so the rate of change of perigee is zero, thus both apogee and perigee can be maintained over fixed latitudes.
This condition occurs at inclinations of 63.4 degrees and 116.6 degrees.
For these orbits the argument of perigee is typically placed in the southern hemisphere, so the satellite remains above the northern hemisphere near apogee for approximately 11 hours per orbit.
This orientation can provide good ground coverage at high northern latitudes.
(from: Orbital, Mechanics, http://www.braeunig.us/space/orbmech.htm)


The orbit in this example places a Dragonfly once a day alternatingly above North America and above central Asia.
