It is possible there was an orbit change thrust performed after the shuttle docked. When the Shuttle docks with ISS, the ISS autopilot is turned OFF. The Shuttles autopilot takes over for the duration of the flight.

My keps are up to date via the Satpc32 software, is there a error due to the large amount of mass now docked on the ISS? or have the keps not be uploaded in a timely fashion to the server I get my keps from?...
Run down of my operation conditions here are as follows...
Radio - Kenwood TS2000 Software SATPC32 + Satpc32 ISS PC - Dell P4 2.4Ghz CPU with internet connection
Is there another method of getting my keps to show more accurate tracking of this big bird?...
