Legend

also known as a NavCom Unit, these computers were used to plot trajectories and hyperspace flight plans between the planets contained in the computer's database. It used the spatial coordinates of the ship in order to accurately chart a course. Many military-grade navigation computers maintained continually-updated databases of the coordinates of billions of planets, moons, and stars to several hundred decimal places, which allowed the computers to accurately plot courses through realspace as well as hyperspace. Civilian models did not require this level of accuracy, but nonetheless maintained incredibly accurate information on the locations of spatial bodies. Coordinates were based on the current location of the planet Coruscant, which was denoted by the coordinates (0,0,0), even though it was not at the exact center of the galaxy. This fact was irrelevant to navigation computers, but vexed many astrocartographers, especially those not born in the Core Worlds.
