The galactic coordinate system is an astronomical coordinate system in which measurements are based on the galactic equator.

Hence a point on the celestial sphere is located by means of $2$ angular measurements:

the galactic longitude $l$, which is the angular distance measured eastwards along the galactic equator from the galactic center
the galactic latitude $b$, which is the angular distance measured north or south of the galactic equator.
