I'm working on a program for ham radio that involves displaying satellites. I'm currently using the Space-track.org database, but the problem with it is that it will give "Saudisat 1C" rather than SO-50, and things like that. Is there a downloadable database that has a friendly name and its corresponding catalog ID?
The database also includes downlink/uplink information (frequencies, mode, etc). It does not include orbital elements (TLEs), which you will have to obtain from another source by cross-referencing the catalog numbers.
I'm not enough of a satellite enthusiast to say how complete or accurate SatNOGS DB is; I do know it is a relatively new project and they are accepting contributions.
PyEphem, a library to calculate (relative) positions of celestial bodies, has a link page that lists digital catalogues you can, at least partially directly import.
