Both rovers move to the closest point on a pre-determined great circle--let's say the equator. One rover travels along the great circle following the rotation of the planet and the other travels against the rotation of the planet.

Nice idea. One possible problem. How do they now they got to some greater circle without having a sort of GPS ? We could assume they can use the information given a priory about the planet and then check the sun/stars to define their positions, although that is really close to say "let's say there is an orbiting module around the planet".
