During its apogee, Molniya 1/21 remained relatively stationary with respect to the earth below for nearly 8 of every 12 hr. By placing three or more Molniya 1 satellites in this type of orbit, spacing them suitably, and shifting their orbital planes relative to each other by 120 deg, a 24-hr/day communication system could be obtained.
