Republic Spacelane Bureau
From Wookieepedia, the Star Wars wiki.
The Republic Spacelane Bureau was the branch of the Old Republic government formed to process and map the galaxy and its hyperroutes. It gave Coruscant its central hyperspace coordinates, fought to end private control of information regarding hyperlanes, and established a protected set of beacons for major pathways to liberate them from the control of privately held charts.
The Bureau was formed quite early in the history of the Republic, probably during the Unification Wars. It was extant c.4,000 BBY, when it serviced the numerous hyperspace beacons used in the Republic until the Great Sith War.
