UWP stands for "Universal World Profile", which is a standard format for the Traveller system. A UWP looks like this:-

Example 0102 A123456-7 Na Lo R 890

InterpretationEdit

"Example" is the name of the principal planet or asteroid belt in the system. This usually means the most inhabited world. Note that the system is not named after the star (so on a star map, our own system would appear as "Terra", not "Sol").

"0102" is the location of the system on the subsector map. The first two numbers are its location as a column, the second its location as a row, so "0102" would be in the first column in the second hex down.

A123456-7 is the system's basic stats, explained in more detail below.

Na Lo are the system's trade classifications, explained in more detail below.

R is the system's Travel Zone. "R" means "Red" -- the system is dangerous or forbidden for some reason and travellers are advised not to go there. "A" means "Amber" -- caution is advised. If there is no entry then the travel zone is "Green" and the system is safe to visit.

890 is the system's PBG code, explained in more detail below.

Basic statsEdit

The eight basic stats consist of individual digits. In general, the numbers 0-9 mean that number, A means 10, B means 11, C means 12, D means 13, E means 14 and F means 15, but other codes are possible and have specific meanings.

They should be read, in order, as follows:-

  • Starport or Spaceport. "Starport" means the starship facilities on the principal planet. "Spaceport" means the starship facilities on other planets in the system. Possible values are as follows:-
Starport codes
Code Quality Shipyards Repairs Refuel
Starport A Excellent Starships Overhaul Refined
Starport B Good Spaceships Overhaul Refined
Starport C Routine None Major Unrefined
Starport D Poor None Minor Unrefined
Starport E Frontier None None None
Spaceport F Good None Minor Unrefined
Spaceport G Poor None Superficial Unrefined
Spaceport H Primitive None None None
Starport X None None None None
Spaceport Y None None None None
  • Planetary size. Possible values are as follows:-

9 Large 13,600 - 15,199
A Large > 15,200
