Intrasystem jump drive

For subspace travel via jump nodes between star systems, please see intersystem jump drive.

The first intrasystem jump drive is the baseline subspace drive, developed before intersystem drives; it was present during the post-age of space exploration and colonization.

Intrasystem jump drives enable a ship to jump from one location in the system to another, quickly and (relatively) precisely. A jump drive of this kind does not need an intersystem subspace node, only the presence of a significant gravity well.

While subspace travel from one system to another in an intersystem jump takes a variable but relatively brief amount of time (the Lucifer's transit from Delta Serpentis to Sol took fifteen minutes), an intrasystem jump is described as "nearly instantaneous."
