JUMP - bearing and speed

[Icosahedron]

Overall streets are pretty empty as well. But jumping into the heart of some systems would be like trying to land a Gulfstream on the streets of Midtown Manhattan during rush hour wearing a blindfold.

Evidently we have VASTLY different ideas of the in-system 'traffic density' of even an A-class starport. I'd say the worst case would be like dropping a Cessna somewhere in a 100 mile wide corridor covering the Darwin/Alice Springs highway! Altitude aside, the blindfold won't make much difference.
And that's assuming no traffic regulation.

I don't think we're gonna see eye to eye on this one.

Actually I was thinking of jumping into Glisten with a target of the Class A Starport. (Or a similar system) Since there is no main world and the Starport is in the middle of a busy asteroid belt, things could get a bit bumpy, especially if you are off in your calculations by hours and a couple of thousand km. In all fairness that is likely to get extremely messy. A typical Class A starport, you are talking about a slight detour, unless you get very unlucky.

In real astronomical terms, when entering the Sol system, to simulate coming out of Jump in the middle of the asteroid belt, roll 100D6.

If you roll 105 or less, then you are too close to an asteroid to avoid impact.

Except that Glisten is supposedly a very dense pair of belts with lots of traffic. Since you are attempting to intentionally jump into the belt, being off by an hour is likely to have unfortunate consequences. Now I am not saying this will happen everywhere. But this and other circumstances could make for some very hairy jump emergence points. (Especially if it takes your sensors a little time to come online.)

Hi !

Well, asteroid belts in one system might look completely different as those in another system. So the situation in Glisten is ... well I really don't know
Anyway the starport in the Glisten system should be expected to be at a location, which supports interstellar trade, allowing safe arrival and departure even at "high" traffic amounts, even with the unpredictable jump time variations ...
Otherwise it should perhaps be declared as somehow unsafe travel zone ...

You might want to look at the GURPS Planetary Survey book for Glisten (the small supplement).

It goes into a great bit of detail explaining how they've got one of the more sophisticated "tracking systems" out there (tracking belt movement and ships). That's on p10.

IMTU I usually use a G-threshold to pull ships out of jump when they reach near a gravity well (the 100-D mark or so). Assuming navigation was correct, at Jump+X hours you should be near a g-well and be able to detect it.

I'm not sure asteroid belts provide the same g-well or not (I'm mean in real life). And whether leaving one would require the "move beyond the 100-D limit" to jump out. If there's no appreciable gravity... My guess is that traffic control would relegate "jumps out" to be X miles below the ecliptic and "jumps in" be relegated to above the ecliptic. But that's just me. I'm sure some whiz-bang, astrophysics professor has much better ideas.

A safe distance above or below the ecliptic could be about the same as a 100-D mark for a "normal" planet.

So for MTU a jump to/from Glisten would involve a "timed-jump" at a point above or below the ecliptic of the belt, or if masked, near the star.
