I know this may be asking a lot, but my Google searching so far leads
me to believe this might be out there somewhere but I haven't found
the right place yet.
I'm looking for some IDL routines that will take a two-line element
(TLE) set for an earth-orbiting satellite and create the nadir
position or track. Extreme precision in the orbit propagation is not
necessary - we will probably be using times within a couple weeks of
the TLE epoch. This will be used somewhat interactively to determine
when a satellite has passed or will pass over a user-identified point
on the earth.
These satellites will typically be outside the range where atmospheric
drag is a factor (normally, earth-observing polar orbiters).
I'd rather not do DLLs because we'd like the same GUI available on
Windows, Solaris, and maybe AIX but we might have to take what we can
find.
