"Ah, Herr Doktor Schrecklich." Eileen chuckles softly at von Braun's suspicious look. "I assumed I'd put myself in the nerve center of the operation, as it were - I can do little at our other sites, but here at least I can coordinate."
She nods to Captian Morgan with a 'carry on' gesture, sipping her coffee and listening to the ongoing discussion without comment - being smart enough to know when the discussions go over her head at suborbital level.
She finally speaks up after a moment's thought. "You're close, Captain. Of course, I'm used to a traditional nine-chevron Gate, but in that you have six coordinates for spatial location in three dimensions, then the seventh chevron establishes the point-of-orgin, which finalises the dialing program's determination of the destination and the route to be taken. The eighth chevron, when used, establishes a different 'area code' - Ida or Pegasus instead of the Milky Way."
Pausing to sip her coffee again, she frowns, then continues. "The function of the ninth chevron hasn't been determined yet. I know Dr. Rush was up to his elbows in researching it but they had yet to come up with any firm answers last I heard. My money in the SGC pool is 'alternate universe dialing'," she admits, chucklinh a lttle before turning serious again. "Of course, with this Gate that could all be out the window and they might well be using something like your system. After all it's entirely feasible that each Gate could have used its own, randomised code instead of a spatial-location code while the system was being developed."
