A simple (solid state) gyrocompass is all that's needed for that, no clear view of the sky/stars and no magnetic field are required. Depending on the size of the planet and on it's morphology that could take very long or be impossible (like on our planet untless the rovers can swim).

how does the gytocompass knows where is the pole? Shouldn't it be calibrated first?
