    Yes, and I quote:
    
    "The release of OI-27 flight software (FSW) will begin the process of
    replacing the orbiter tactical air navigation (TACAN) system with a
    global positioning system (GPS)."
    
    This is from a very large PDF file - the complete Space Shuttle manual
    listing everything you want to know about the Shuttle and its systems.
    I downloaded it from NASA a few years ago.  It is about 20 MB in size.
