The Universal World Profile (UWP) is a set of codes describing the qualities and characteristics of a world.

  • In some older, early Imperial circles, it has been known as the UPP or Universal Planetary Profile.

Please see the following AAB Library Data articles for more information:

Description (Specifications)

UWP Typical Format under T5SS
Name Hex Physical Stats Base Code/s Trade Classifications Extended Stats Allegiance Code
Roup 0407 C77A9A9-6 S Hi In Wa A323 Im or ImDa (2 or 4 digit)

Thus the planet Roup is located in hex 0407 in the sector, it has physical stats of C77A9A9-6, a base code of S(cout) and has trade classification of "Hi In Wa", the extended data is A323, and has allegiance to the Im(perium).

The extended stats include:

Basic UWP Stats

Physical Stats (...the entire sequence):

SAH Sequence (planetology):

PGL Sequence (socioeconomics):

TL (technology):

UWP Format Dictionary
# Category Explanation Remarks
1. Starport A Starport is an establishment for the landing, servicing, refueling, launching, and control of starships.
  • Starports range in quality from A (the best and most extensive) to E (the worst, little more than a spot of cleared ground), and X.
  • A secondary set of spaceport ratings includes F, G, H, and Y.
Stand-alone qualifier.
2. Size Worlds are classified according to their physical size (Planetary Size).
  • Only Mainworlds (worlds or planets) of interest are recorded.
  • Planetary size and density are the two strongest indicators of surface gravity parameters.
  • e.g. Gas Giants are simply classified as Small (SGG) or Large (LGG).
Part of SAH sequence.
3. Atmosphere The Atmosphere code is a UWP code to represent the breathing environment encountered on the world.
  • It represents the mixture of gases and other elements that may be present on a world (planet).
  • Atmosphere greatly affects the habitability of a world.
Part of SAH sequence.
4. Hydrographics The Hydrosphere represents (Hydrographics) or the liquid content of a world, usually water on a conventional life-supporting world (planet). Part of SAH sequence.
5. Population The Population UWP code is an indicator of the world's population of Sophonts.
  • This figure represents the exponent (number of zeros) which follow the first population digit (this digit is outlined in the extended data).
  • High Population worlds are generally shown in all caps (e.g. ROUP) on sector/subsector maps.
Part of PGL sequence.
6. Government Government is the method by which a subplanetary (...smaller than a world), planetary (world), or interstellar (multi-system) state or community, leads (governs) itself.
  • Standard UWP codes exist to explain most of the most common government types.
  • The study of governments, governance, and other related subjects is known as political science, a type of social science.
Part of PGL sequence.
7. Law level Law Level is an indication of the relative oppressiveness of the world (planet) of whom the law serves more: the inhabitants (...and visitors) [distributed power] or the government and politicians of a planet (...or polity) [centralized power].
  • The more centralized or autocratic a government (polity) is, the more likely the higher laws codes will be more oppressive.
  • The less centralized or more distributed a government (polity) is, the more likely the lower laws codes will be more democratic.
Part of PGL sequence.
8. Tech level Technology Level or Tech Level, commonly abbreviated TL, is a measure of technological capability. Stand-alone qualifier.

Extended UWP Stats

The Expanded UWP Stats for a system may include:

COG Sequence (habitability):

Other System Data

History & Background (Dossier)

Systems information is also available as full astrographic charts (holocrystal), or the summarized Extended System Profile which does not have projected orbital postions, navigational and approach codes and frequencies.


Stars are literally the center of any stellar system and while not directly noted in the UWP, they are listed in a standard T5SS planetary description as indicated on all star charts for millennia.

  • Stars are notated with a type and intensity: e.g. M5 V
    • M5 is a red giant star
    • V is the intensity or brightness.

Gas Giants

Gas Giants are very important to starfarers because they are one of the best sources of fuel if present within a Star System.

  • Systems without gas giants may become important defensive positions for interstellar navies.
  • Two codes, SGG and LGG, are in common use by everyday starfarers, although scientists and astrographers often use far more complex codes.
UWP System Format Non-Mainworld
Code Expanded Remarks
LGG Large Gas Giant Not for mainworlds.
SGG Small Gas Giant Not for mainworlds.
