    I'm looking for pointers to good example code/descriptions of
    algorithms for handling TLEs and converting between multiple epochs
    and orbit propagation models.
    
    The aim is to improve the existing TLE-handling Tcl code in SaVi
    (http://savi.sourceforge.net/), which is really only good for
    satellites whose TLEs use the same epoch right now. SaVi has
    reasonably fair visualisation display capabilities (for a free
    package), but it's all a bit abstract and idealised, and not yet
    useful for the kind of real-time simulation needed for tracking
    or observation.
    
    thanks,
    
    L.
