A navigation computer was a computer used to make the necessary calculations to navigate at faster-than-light speeds known as hyperspace. It was also sometimes known as a navicomputer or nav computer.
Although navicomputers were used in most of the known galaxy, they functioned poorly in the Unknown Regions. As a result, the peoples of the Unknown Regions used Force-sensitive navigators with the power of precognition instead of navicomputers. In particular, the Chiss Ascendancy used Force-sensitive children known as ozyly-esehembo as navigators.
