Orbit, or OR-Bit in the official GTA III website, is a business in Grand Theft Auto III. The headquarters is located in west Belleville Park, Staunton Island. Its advertisements are displayed in Torrington and other parts of the city. It is unknown what is the purpose of this business but, based on the building's in-game model name
Hotel3.dff, it could be a hotel. Orbit seemed to have importance during the development of GTA III because its headquarters is featured on the official website and in the game manual.
