A Rebel astrogation officer.

Astrogation was the science of navigating spacecraft through realspace and hyperspace.

Two tasks defined astrogation: (1) determining present location, and (2) planning a safe and reliable means of reaching a destination. The former was performed by those skilled in astrocartography familiar with star patterns or automata. Astronav charts were used to map areas of space and could be used to plot courses through hyperspace. The plotting of a course was generally handled exclusively by astromech droids or navigation computers.

The knowledge of ones whereabouts in space and other celestial objects were vital to navigating hyperspace, as incorrectly calculated jumps could mean a ship could collide with a planet, star, or other body.

Behind the scenesEdit

Astrogation is an original sci-fi exclusive word which means "star navigation." Since etymologically and historically the part "navi-" refers to terrestrial ships, it has been replaced by the prefix "astro-".
