How long should it take to plot a micro jump?

How long should it take to plot an insystem micro jump? What kind of difficultiy would it be?

It would depend on several things, like the astrogation skill of the pilot or navigator, if their ship has a navicomp, do they have an astromech, etc. All these will modify the difficulty and the time it takes to plot a course, even a microjump.

[Endwyn]

A microjump is more difficult and take a little longer to calculate. Look up the difficulties for ploting an unknown course; that's a mircojump. Most astrogation journeys are on established routes; with the exceptions being rare (scouts, military surprise, desperate characters, ect).

[Boomer]

Most microjumps I know of are emergency manuvers preformed instantly by hitting the "Jump" button and going to hyperspace for anywhere from .01 seconds to 3 seconds and dropping out to plot a real course.

The chances for disaster are quite high, and can be reflected in game rules as purposefully bombing the atsrogation roll and requiring a D6 roll to determine wether or not this creates a complication.

A non-emergency, in system, microjump should be a bit easier, depending upon how you do it. The sensors have a much smaller course to check over for plot, and you may even be able to see all the way from start to finish by looking out the window (more likely with telescope). The difficulty comes in the fact that Hyperdrives are very, VERY long range boosters that work by accelarting the matter of the vessel and all within to blah blah blah...

The point is, your gauranteed success in plotting the course so long as that wild doesn't say "you forgot about the shoe someone chucked out a window". But is the hyperdrive precise enough to stop in time without taking any stress.

Most likely it is, and you can easily jump around a system in minutes in seconds. But don't push your luck.

As in IIRC. p.116:

Sublight Benchmarks:

Anywhere from 10 to 48 hours to fly from a star to the outer limits of the system, depending upon distance and the presence of any hazards such as asteroid belts or gas clouds. (It takes about 15 hours to reach the outer limits of a "representative" system composed of a single yellow star and less than a dozen significant planetary bodies.) Often, pilots find that it's quicker to travel between planets by making a "micro jump" in hyperspace. While very precise navigation coordinates are necessary for this type of jump, such trips can be completed within an hour, compared
to sublight "intersystem" trips taking many hours.

This quote isnt saying if the trip duration is with calculation, but as it says completed, it could be meant this way.

Imho the microjumps used for scouting are longer than insystem microjumps, so they shouldn´t be used here for guessing. You should be able to get all relevant coordinates of obstacles for a insystem microjump with your sensors.

IIRC, p. 118:

Calculating a route takes one minute if the character is using a well-travelled route or is using precalculated coordinates. (In emergencies, a character can try to jump into hyperspace in one round instead of one minute. The astrogation difficulty is doubled and the character rolls each round until he either beats the difficulty number or suffers an astrogation mishap.) Calculating a route between known systems takes about half an hour.

Taking this quote into account, i would guess calculating duration for a insystem microjump between 1 minute and 30 minutes. It should be more to the lower end, maybe around 10 minutes.

I can see why he's asking for the game mechanics of doing this; it's a technique used in the novels to get to a point in space (basically line of sight, or at least line of sensors...) quickly enough to be of some good in a space battle.

This has given me another idea... mounting small, perhaps one-shot hyperdrives on projectiles for battle. Everything I've ever read says that if there's an object in your way while you're in hyperspace, if the gravity isn't enough to pull you into realspace, you crash into it. Take that a step further: if you could mount hyperdrives on missiles, you could maybe negate or greatly reduce the protection that shields give. This technology might be too far-fetched or too expensive to use, but think of the possibilities. I know it sounds way out there, but I'd be interested in hashing this idea out a little. C'mon, Argamoth and all you other physics and gaming experts out there... Tell me if this idea's too radical to be possible or if it has a kernel of merit, given some more thought...

[Krapou]

If I remember correctly, this was maybe done with the Galaxy Gun (a superweapon near Byss)

However I don't know much about this superweapon, so if someone could explain (maybe in another thread)

[Gry Sarth]

I like the idea, sure it's "out there", but plausible within the universe. Certainly this kind of weapon would be something very expensive and quite unwieldy. Even a one-shot hyperdrive should be very bulky, hindering the missile considerably. But still, this would be a nice strategic weapon, not as efficient as an ordinary missile, but with a great surprise factor. Firing it accurately would be a very hard task.

[Jedi Skyler]

Well, the idea struck me that if we have devices capable of sending communication transmissions through hyperspace, then perhaps such an enabled missile might not be quite so unwieldy. I know most hyperdrives ARE these big, cumbersome devices, but I also figured that their size is determined by A)The size of the ship they're for, and B)How fast they'll propel the ship through hyperspace. My thought is that these missiles would be only capable of microjumps, maybe only in-system, and if it misses, it self-destructs or is destroyed by the ship that fired it. That would prevent it from falling into enemy hands. The self-destruct interval could be pre-programmed into the device to allow the deploying ship time to get away. This could be overridden by a transmission from the ship as well.

[Argamoth]

I could see it used like an anti-capital ship torpedo, with a nulclear warhead or something attached. StarDestroyers and other larger ships probably have plenty of computers to calculate the coordinates for the torpedo. But a weapon like this would probably not be effective vs. rebels, on account that their ships are too small to reliably hit or just don't present a worthwile target. And the rebels themselves probably don't have the resources to to it themselves.

Another way to use this, though, could be to attach a bajillion bombettes onto the the h-drive. H-drive makes a jump, lands in the midst of the enemy fleet, and realeases a bajillinon proton torpedos at ships and fighters. Or a massive EMP/ion pulse.

[Jedi Skyler]

Those are some good ideas. If the hyper-capable unit suddenly drops into the middle of a formation and immediately fires off a volley of missile or torpedo fire, SOMEONE'S going home in an urn. If there's anything left, that is...

[garhkal]

I could see this as a imp planetary use weapon, say it fires from the planet, and 'micro' jumps to the edge of the system to engage any ships incomming...
