A starbase is a facility that offers various services to starships such as maintenance, resupply, medical facilities as well as rest and relaxation for the crew. A starbase is often military in nature although research and trade bases are fairly common. The term "starbase" is almost exclusively used by the United Federation of Planets to denote Starfleet installations although the term is applied to nearly any space station.
Starbases can be located in deep space, within a system, in planetary orbit or on a planetary surface. Some facilites have combinations of these, such as a ground base with an orbital waypoint.
