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 classified.zip 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,

Chris
