High-end & low-end Nav Computers

[Ning Leihrec]

Here's a breakdown of nav computers I'll be using in my upcoming campaign...
Thanks for everyone's input. I found Crmc's solution highly applicable.

A nav-computer, rather than being capable of unlimited jumps, will have a base difficulty modifier which is applied to the difficulty of any jump it makes. It will also have a modifier that increases the difficulty based on the number of jumps made since the last time the ship downloaded a chart update. Larger capital ships will have lower difficulty levels and modifiers, and can make dozens or hundreds of jumps without difficulty, but smaller craft (starfighters and space transports) have more limited and less capable nav-computers, with higher base difficulty and a modifier that ramps up more rapidly.

by those rules I separated Nav Computers into 5 classes. Still tweaking the price points, but this is the general idea.

Class I Nav Comp
diff: +10 (+5/jump)
cost: 1,000

Class II Nav Comp
diff: +5 (+1/jump)
cost: 2,000

Class III Nav Comp
diff: +0 (+1/jump)
cost: 5,000

Class IV Nav Comp
diff: -5 (+1/5 jumps)
cost: 15,000

Class V Nav Comp
diff: -10 (+1/10 jumps)
cost: 60,000 (black market)

So say a ship has a class 2. It adds +5 to the TN for any jump it makes base, +1 per additional jump made since it's last nav update.
So a ship operating 5 jumps for a rebel mission, and has had NO update prior, would be a base 6 for jump 1, 7 for jump 2, 8 for jump 3 and so on?

No. The base is a modifier to the difficulty of the jump according to the RAW, which then scales up with the number of jumps.

I just watched the Rebels episode "droids in distress" where our heroes took the star tours ride (not joking that really is the ride at disenyland) from Lothal to Garrell. That navigation computer probably only has two jumps there and back and travels that route twice in a twelve hour period. That navicomputer would give a bonus to that route and be next to useless to any other giving a high penalty for going off course.

Should it be considered that a successful astrogation roll for a jump not need to be rolled again within a short time frame unless the player wants to try to get a higher roll to shorten trip time?

That makes sense to me. Do you think the recently traveled route should be granted an automatic success or just a bonus? And if the latter, how much of a bonus?

When you said base 6 above, I read it as you saying the base difficulty for the jump, not the base difficulty for the modifier.

Sith happens. I've got my share of confusing posts too.

Ammending my stats for Nav Computers. The Class I is too underpowered and dangerous to make sense. It's almost as bad as no Nav Comp at all. Had to fix the list a bit...

Class I Nav Comp
diff: +5 (+5/jump)
cost: 1,000

Class II Nav Comp
diff: +0 (+3/jump)
cost: 2,000

Class III Nav Comp
diff: +0 (+1/jump)
cost: 5,000

Class IV Nav Comp
diff: -5 (+1/5 jumps)
cost: 15,000

Class V Nav Comp
diff: -10 (+1/10 jumps)
cost: 60,000 (black market)

[CRMcNeill]

Easily done..

Class I Nav Comp
diff: +5 (+5/jump)
cost: 1,000
Weight: 1 Ton

Class II Nav Comp
diff: +0 (+3/jump)
cost: 2,000
Weight: 2 Tons

Class III Nav Comp
diff: +0 (+1/jump)
cost: 5,000
Weight: 5 Tons

Class IV Nav Comp
diff: -5 (+1/5 jumps)
cost: 15,000
Weight: 15 tons

Class V Nav Comp
diff: -10 (+1/10 jumps)
cost: 60,000 (black market)
Weight: 50 tons

That works. The Class I & II are small enough to explain how a navcomputer could be shoe-horned into something like the back seat of a Y-Wing, which is what WEG did to make the Y-Wing Longprobe.

And why the top end ones are generally NOT On small freighters, but larger cap ships.

What should be the cost of a chart update? Would it be included in the ship service and replenishment fee from GG6?
