for my 2 credits.
a few observations on Star wars Hyperspace:
* it is not a place you can "Hang out" in. (Compare to Babylon 5 where a taskforce can wait in hyperspace for a signal the jump in.)
* entry points need to be individually calculated. fleets are seen jumping ship by ship. Notable exception the Katana-fleet. but that was a plot point. it could as easily be achieved by linking computers and pre-calculated solutions dispensed through said computers.
* small craft with hyperdrive can jump with the help of an astromech or precalculated coordinates they requite a lot of power/fuel to reach hyperspace. I am not sure, but I believe <PERSON> makes a remark about not using fuel in hyperspace.(X-wing series)
* there seems to be no way of changing direction once in hyperspace. or velocity.
* gravitational hazards. captain solo's boast about the Millennium falcon and the "Kessel run", a route that has the Maw a black hole along it's path with an endpoint of moving tradeships, implies that the trick of efficient hyperspace travel is about avoiding gravity wells. and their massive counterparts in real space. ie the higher the ships speed the closer they can travel to the center of the well. which in turn shortens the distance traveled.
* The technical manual puts the falcon on 0.5 past lightspeed and attributes her success on her power maneuverability and speed. 947
and a suped-up hyperdrive and tricked out nav-system.
it would seem that the angle and direction and speed of entry into hyperspace is key for successful travel. if it is true that corrections cannot be made in hyperspace then a relative straight line needs to be plotted. and in the case of trying to escape a chasing star destroyer you will have to dodge and weave to avoid getting hit. constantly changing the variables.
On a side note:
<PERSON> is implying that that jump to the Katana-fleet was more an act of calculated despair then a tried and true tactic. especially since hyperdrives come equipped with a safety cut-out that drops you out of hyperspace when to close to a gravity well. the risk would be minimal. and a short distance was all they needed.
In Knight of the old republic a reference is made to a powergrab by a sith lord. where Republic hyperspace explorers were used as proof of imminent Republic invasion. there is however no saying whether they calculated the jump or just took a stab.
In regard to the space around Coruscant. The moon of Borleias lies in a system close to Coruscant. and used to be a stopover before the last leg to Coruscant. but had been ignored because of more powerful hyperdrives. it was used as staging ground for the invasion of Coruscant near the end of the galactic civil war and the later Yuuzang Vong invasion. 963
