The spaceship seemed to be there as a kind of Headquarters for the Predator aliens. Other than to hunt, no explanation is given as to their presence. Viewers have suggested that (1) each Predator was sent out to hunt. They all go hunting in various places at the same time or in close time frames in order to minimize the chance of being discovered. Once their hunt is complete, they return to the headquarters and head back into space. The predator in this film was simply the last to complete his hunt. (2) The ship was there to collect the Predator before his hunt was complete because he wasn't following the ritual and was being too high-profile.
