Re: Question about the age of available TLEs

Hi all,

After following this discussion, I just want to clarify where Heavens-Above
gets the TLEs used for predictions.


For the classified objects, we use Mike McCants file.


For all other objects, we use Space-Track as the source, using a script
which checks for updates every 4 hours. If the TLEs for the ISS are the same
as on the NASA page, this is pure coincidence.


Best wishes,
