Prepping for the Table: Star Tracks 2025-? (fourth page)

 Travel Speed- 1 through various higher numbers depending on technology aboard the starfaring ship. Often called "Warp," the number following the mode is how many light-years are traversed in ten hours. "Travel 1" equals one light-year in ten hours, and so on. 
An Astronomical Unit, or just "Subspace"- Around 93 million miles traveled in the course of ten hours.
Half Subspace- A unit of Subspace traveled in twenty hours. This is known as "Patrol Speed," when vessels are scanning the areas around them.
Orbit- The spacecraft slows down enough to maintain what is colloquially called a "stationary orbit" around a larger object.
Fall- Speeds where the spaceship is effected by the gravitational forces of the masses around them. Also called "Pond Speed."

Hawaii Zero
   Earth's interstellar maps are considered some of the better maps that aren't kept secret by their makers of known space. Earth Central is the starting point of the official United Star Systems Alliance maps. Coordinates are in order of the X,Y, and Z axes. and those integers are where locations are in comparison to "Hawaii." The Sol Star System the center, if not actually at its center, of the USSA and home of the U5S military and governmental ministries. 

Space Routes
   Most of the time straight lines just aren't helpful. There's a lot of stuff that just is in the way. On top of that the stars and whatnot that are visible to planet's night sky just aren't where they appear to be anymore. Now that Faster-than-Light travel is actually a thing, finding out where the objects are in real time (so to speak) takes a lot of exploration. So because of this, starship exploration of the galaxy tends to resemble the Age of Sail, where gravitational masses moving along varied vectors replace currents and environmental conditions.
