If a person sets up a GPS base and a couple rovers, he gets a few baselines.

If he sets them up in the morning, picks them up at noon an re-sets them in the afternoon, he gets repeat vectors. Everyone wants repeat vectors when they can get them.

If the GPS units are setup all day long, there are longer observations, but no repeat vectors.
