This article details the sector-based system that is the common standard of the Intergalactic Navigation Consortium. For the 3-dimensional polar system used by Helics, see Basilicus Prime Coordinate System
The Galactic Coordinates system in the Basilicus Prime galaxy utilises a set of numbers to describe a position in terms of sector. It was developed by the Intergalactic Navigation Consortium to become the standard between races, mainly for common and categorisation purposes. Trans-galactic routing and scientific study typically use the more versatile but harder to interpret 3-dimensional polar coordinates of the Basilicus Prime Coordinate System. Despite being a cooperative effort between species, the system still uses the Galactic Meridian between Inatus and Helis for convenience.
The coordinates are given in two parts separated by "::", with one or both included depending on scope, to the following form:
[Rim Number . Radial Number :: X // Y // Z]
The first part is called the Galactic element. The Rim number denotes which concentric zone the sector belongs in. For example, Black Hole Inatus resides in Rim 01, while the Dejenna System is in Rim zone 19. The Radial number is that of the preceding galactic radial (a line from core to rim) when read in a clockwise direction; for example, both Aega and Hollowstar reside in Radial zone 56.
In the case of Basilicus, the galactic meridian is a line drawn outward from Black Hole Inatus to Helis. All Rims have 64 sectors except for the following; 03, which has sixteen; 02, which has eight and 01 which has just one. Some sectors are named, while the less notable may be referred to simply by galactic co-ordinate.
The second part, often used separately, is called the Sector element. It consists of three numbers that describe a position further in terms of dly from the sectors origin (the point where the Rim line and Radial line meet). Of these, the X value reads in an arc parallel to the galactic circumference, while the Y is the distance from the Rim line. The Z can be either plus or minus and resides on a line perpendicular to the galactic plane.
