site designation by lat/long
When I try to get your website to generate predictions for the ISS, it never accepts the name of the city which I enter. Is there a way to get your tracking program to accept my lat/long coordinates instead of a city name? Please advise.

Re: site designation by lat/long
Hello Grover,
Beter you use sat trackings software, because the tracker
here in IFC does not always give the right position.
It requeres a few minutes to configure and you can
follow the ISS without internet.
Good freeware trackings software:
Satscape:
http://www.satscape.co.uk/iweb/Satscape/Front_page.html
Orbitron:

After configuring the software, do not forget
to download once in a week new orbit calculations (keppler data).

Thanks for your response.
Thanks for your response. The reason I was asking was because a friend told me that the predictions which I generate and send to him weekly are within a few seconds of matching observations, whereas the predictions he got from your site (or so I understood) wre several MINUTES in error. I merely wanted to compare your values with my own.
I am a retired professional engineer/scientist from Sandia National Laboratory in Albuquerque, New Mexico, where I wrote computer programs for tracking various satellites in which Sandia had an interest. Some problems required precisions of 5 arc-seconds or less in position, which required some doing!
I might suggest that the element sets are better known as "elsets" for short, rather than "kepplers", especially as "Kepler" has only one "p". Of course, different folks have their own jargon, I understand that.
Best regards, and thanks again for your response.

Hello Hughes,
ISSFANCLUB is (technically) owned by Alain (IZ6BYY).
Alain is outside his country and very busy with his work.
If I doubt on my trackings software, I always compare
it with the ISS position on this website:
