Orbit design

A satellite on a ‘Repeat Ground Track Orbit’ are obviously Repeat Orbit but others can be too if they are timed just right. If an orbit took 24 hours then a polar orbit would be a Repeat Orbit. Satellites can be characterized by the intervals within their orbital period during which they are in line-of-sight communication with at least some ground station. Those intervals will not generally cover the whole orbital period, because some ground station may be out of order or because the satellite is flying over an area without ground stations. The orbit designer can specify that satellites are placed in orbit at certain time differences between them, such as, satellite A may be m1 minutes before satellite B in the orbit and B may be m2 minutes before C, and so forth.
