How does the (real) shuttle prepare to intercept the ISS? After climbing to orbit, I tried following Tex video tutorial for docking and on orbit synchronization stage, doing so many burns at rendezvous point will get me faster to ISS, but I think it's not very fuel consumption-wise. A much fuel conservative approach seems to be having an orbit like 180 km x 350 km. It will take longer to intercept the ISS, but when less burns (no burns at rendezvous point, just wait to catch the ISS). With this orbit, I get around 2-3 days until interception, which is fairly accurate, comparing to a real flight plan. Also, having an orbit lower then 150km will experience atmospheric dragging, which I try to avoid.
Which approach would be the most realistic one? Also, when is the burn for orbit inclination correction made?
