Just installed a 12 x dedicated GPS network at 1588kms staggered at 15 degree intervals. While setting up, my orbiting station was happily receiving a signal that gradually improved as more sats went up. I did some IRL work, came back an hour later and fit a receiver to a rover to test surface accuracy and went to launch. Fps dropped to less than 1 (on a 670gtx) and bogged everything down. Tried turning off receiver and it clicked off then back on again. Reverted to VAB, removed receiver, fps came back to 60+. I tested the station (at 100km) and it bogged as well. Did your suggestion of "GNSSacronym = GPS" (all my sats have GPS prefix), restarted, loaded receiver and sitting at launch with GPS signals, visible sats 4, accuracy 0.2m with 60 fps again. Hope this helps solve this little issue. Time tested would be *after* the aforementioned update. Mod was d/l'd from Spaceport about 4 hours prior to post time.
