    *facepalm* heavensat was one of them... i was thinking that heavensat was an 
    online web based tool :embarrassed:
    stellarium is another one but stellarium is primarily an astronomy program that 
    has had satellite tracking added in later... the current release is ok for 
    things like this but it doesn't remove satellites from the list that are not in 
    the TLE files any longer... it converts the selected TLEs to a JSON file... the 
    next release is reported to automatically remove missing satellites from the 
    JSON file... i have been quietly and unobtrusively trying to get them to forego 
    conversion of the TLEs to their JSON format and just use them directly as every 
    other satellite tracking program does... the size of the JSON is much larger 
    then the raw TLEs... this is especially important when loading TLE files with 
    10000+ satellite entries... they can use their JSON file to store the radio 
    frequencies and other notations and keep them synced by norad number if they 
    want but they really do need to just use the TLEs directly... i don't know why 
    they ever converted the TLEs to JSON in the first place... other than it is a 
    neat new technology :? [/digression]
    there are a few older DOS style ones that i used to use which i can't find on my 
    system right now :/  but it has been a long while since i used them and i may be 
    misremembering their capabilities... i think one was written by mike mccants but 
    i'm not sure... i'm recalling a round visual port with the star field and the 
    track of the satellite plotted across it... it was using one of the older DOS 
    graphics modes to draw in... uncle google might be able to point them out...
