[Star Wars] Astrogation

[Phaelen Bleux]

I'm trying to collect bits a pieces to start a SW campaign at some point. I began looking at Astrogation as it might apply to SW. A few quandries:

(1.) How hard should Astrogation skill be? M/A seems a little generous for the SW universe.

(2.) What Complexity computer would be needed to handle astrogation calculations?

(3.) How large of a database to you need to keep track of 180 billion objects in constant motion with X,Y,Z coordinates and basic planetary descriptions?

Just off the top of my head, I would place Astrogation as a Very Hard skill with no default. Minimum equipment for astrogation would be an astromech droid, which I would say would have you rolling at -2 to skill, unless it was an especially good astromech droid. An on-board astrogation computer (rare on even the biggest fighters, but common on everything bigger) would allow you to roll at full skill. There could conceivably be high-quality computers that might give as much as +2 to skill.

Updating your database frequently is important to keeping everything safe. After a week without updating your computer, you're at -1; after a month, -2; six months, -3; a year or more, -5.

I couldn't say about questions 2 and 3.

I wouldn't bother changing difficulty from whatever Basic Set offers. Instead, I would take a closer look at the range penalties to be employed for the rolls, and what Equipment Modifiers should be.

This is another one of those cases where it is unclear how exactly should Intuitive Mathematician behave.

Do range penalties generally apply to Navigation rolls? I could see using the Long-Distance modifiers for this, though it's not mentioned in the skill description. Of course, while that keeps terrestrial range penalties relatively modest, interplanetary and interstellar distances would still give oppressively heavy penalties.

If Astrogation can be done with just a hyperspace chart and scientific calculator, then Intuitive Mathematics would count as basic equipment. If it's considerably more involved (requiring a computer to model the projected path and all nearby bodies in 4D, for example) then IM isn't sufficient, being Improvised Equipment at best.

Agreed. The hyperspace mishaps that occur in the fiction all seem to come about from external factors, like damaged equipment, inadequate charts, and insufficient plotting time.

Or you can declare that a 2-pc jump is +0, and use the Speed/Range Table, substituting parsecs for yards. Just an example. It's your campaign, some decisions have to be made.

.

Intuitive Mathematician outrates a scicntific calculator by several orders of magnitude. IM is capable of doing engineeering design work rathert hasn jsut simple (or even not quite simple) calculations.

Also, by example of AI characters and descriptions of how to do them, if you have IM, Photogrpahic Memory, Absolute Time sense and possibly Enhanced Time Sense you _are_ a computer either literally or figuartively.

Ah, looks like I got it mixed up with Lightning Calculator. Yeah, if a character is an Intuitive Mathematician, their brain basically is a computer, so that trait combined with accurate navigation charts is all that's needed.

Which does beg the question of why any droid brain capable of sentience might be incapable of Astrogation. Presumably it requires a higher Complexity than does AI - either because it's truly that difficult (in which case IM may still have trouble with it) or because the Complexity necessary for Star Wars AI is lower than the GURPS assumption.

I disagree.
Several fighters can jump into hyperdrive in the movies.
This tells me its not that hard a skill, you dont train that many people to do something like that and failures would be too big a problem so they would have to buy up the skill.

All fighters with hyperspace have Astromechs. At least according to the WEG rules, Astromechs aren't capable of calculating a new hyperjump but can hold preprogrammed settings for several jumps with known entry and exit points.

Sure but the post I replied to was using Astromechs as a -2
