Vman just a quick run down on Molniya orbits.

Here's the best picture I could find: pentriad.com
of a Molniya Orbit
A Molniya orbit is a specific form of a highly elliptical, semi­synchronous orbit. It has a 64 inclination, 0.7 eccentricity, and perigee over the southern hemisphere. A satellite in a Molniya orbit spends 11.7 hours of its 12 hour period in the northern hemisphere. This makes the Molniya orbit well suited for communications satellites intended to provide coverage in the extreme north where access to geostationary satellite is generally not feasible.
(From fas.org

and another explaination at fas.org

Molniya is also a class of satellites and launch vehicles (basically a 4 stage Soyuz) all from the design bureau of the same name!
