Astrogation Rules in Star Wars: New Republic | World Anvil

Astrogation Rules

When you want to travel between two systems you have two options:
  1. You may travel along existent, safe routes.
    • This method takes less time to calculate and is much safer.
  2. You may chart a new direct route between the two systems.
    • This method tends to shorten travel time and is very unlikely to be guarded.

Charting Your Own Route

 

1. Open NavComputer Website

Use http://www.swcombine.com/navcomp/

2. Create Route

Click on the starting planet and the end planet. The names may not be canon and not all locations are on the NavComp website so you may need to use the closest planet.

3. Roll Astrogation check

Roll your Astrogation skill check based on the rules above.

4. Input Results

Advantages or Threats will affect the Piloting Skill number, this represents how skillfully you can find the shortest route.
  Piloting Skill Input:
Result Input
3 Threat 0
2 Threat 1
1 Threat 2
No Result 3
1 Advantage 4
2 Advantages 5
The speed of the ship is a major factor, look at the Hyperdrive class of your ship and input a number into Hyper speed based on this chart:
  Hyper Speed:
Class Input
Class 15 1
Class 12 1.25
Class 10 1.5
Class 3 5
Class 2 7.5
Class 1 15
The formula is Class * Speed = 15 or 15/Class = Speed   The Travel Time listed at the top of the page will be the time it will take to reach your destination.
