SONG

SONG is an acronym for the Sensory Observation & Navigation Grid, a sophisticated network of beacons, buoys, outposts, and satellites affixed at various points at the frontier of the CDU's territorial space as well as throughout the interior. In and of itself, SONG isn't intended to be a defense system, with no integrated weaponry or shielding installed. It acts much more in a passive role, detecting and recording any vessels in the area. A SONG installation also transmits travel coordinates automatically, as well as coordinates of known hazards to avoid or navigate through.

Several SONG posts are garrisoned by either small units of Provincial Army or Marines, with some of the larger ones, at strategic locations, hosting a warship or two. These posts have been given informal names by their inhabitants, certainly more illustrative than the alpha-numeric designation each post normally is cast with.
