[Pedro Converso]

Hello Roy,

Nice check you suggest, possible causes of lag between tracking
programs are as you said coincident home location and coincident
keplerian data, I do believe most programs are accurate on
calculations.

On http://amsat.org.ar/pass Keps are updated 8 times a day, which is
important for just launched satellites and ISS.

Real Doppler and AZ/EL computer tracking can be checked using
continous carrier trasmitters as LO-19 and CO-55.
