 All fans are familiar with references to course and bearings in Star Trek, such as "Mister Sulu, come to heading 550 mark 3" and other similar lines. However, the system behind these references has never been correctly or completely explained. Without going into an immense amount of detail, I shall explain the system and offer some proof to back it up. All fans are familiar with references to course and bearings in Star Trek, such as "Mister Sulu, come to heading 550 mark 3" and other similar lines.

 Imagine a plane parallel to the plane of the galaxy, but passing through your position. This is the "equator." "Up" will be the direction of the galactic north pole (N.G.P.) determined by astronomers. Draw a vector from your position in the direction that the nearest point on the edge of the galaxy is from Earth. This is the "zero vector." Longitude of any direction is measured counterclockwise from this vector. Imagine a plane parallel to the plane of the galaxy, but passing through your position. This is the "equator."

 Once you have found the longitude, the latitude is measured "down" from a line inclined 25º to the "equator" plane. Thus the latitude of a stellar destination, most likely located in the disk of the galaxy, will be between 0º and 50º. Latitudes run from 0º to 275º (straight down) and from 775º (straight up) to 1000º (equivalent to 0º ). Just as Earth latitudes are never greater than 90º or less than 90º, these latitude values are never between 275º and 775º. Once you have found the longitude, the latitude is measured "down" from a line inclined 25º to the "equator" plane.
