[Star Trek TNG] What is meant of "full stop" on the Enterprise?

The Enterprise is in space and velocity, by definition, must be in reference to something. On Earth, the reference point is typically the ground. What is the reference point the Enterprise uses? "Full stop" can't simply mean acceleration=0, there are several incidents in the series where they are "stopped" in front of an object.

It means stopped relative to the local spatial context.  Absent all reference points, it just means engines to zero.  In the case that there are local references to be used, it means stopped relative to them.
