Here's a collection of the latest NASA keplerian elements I have for the various interesting satellites. These can be used either with my programs or with the W3IWI program versions available from AMSAT. These can NOT be used with simple equator-crossing predictors, but since the W3IWI program can be run even on the lowly ZX-81, there isn't much excuse for still running obsolete code!

Where does one get one fo the programs to calculate passes from the
orbital elements? I have asked several times on different lists and
have yet to get a reply. Could one be posted to Info-Hams?
