Re: [amsat-bb] Nova vs. SatPC32 orbit numbers

[Dan <ddann@xxxxxxxxxxxxx>]

I tried switching from perigee to ascending node in Nova.  In Perigee 
the orbit numbers were 1 to 2 higher and in Ascending Node they were the 
same or 1 higher.  I tried using the same kep file for each with the 
same results.  I copied the Nasa.dat file from Nova to the SatPC32 
directory. 

I like putting the orbit numbers in my log and on the QSL cards.  It 
makes it interesting to see how the orbits progress, especially right 
after a lunch and the high numbers of the older birds.  I guess it is 
not really that big of a deal, but just thought it was strange looking 
when I had them both open at the same time with different numbers showing.
