[amsat-bb] Re: HRD 6.0 and Satellite Tracker

[Jim Jerzycke]

There are several different orbital prediction models in use, and I 
would guess that they are not using the same one.

SatPC32 gives you a choice in the setup options, but it's been so long 
since I've used NOVA, I don't remember if or where the oprion is located.
