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.

Thanks to Dave, and many others who contacted me about the use of
Satellite Tracker in HRD 6.0.
It was exactly the kind of input that I was hoping for.
A couple of other questions:
1.) I've noticed that Nova for Windows and SAT32PC display slightly
different data regarding AOS, LOS, Azimuth and Elevation for a given
satellite. This seems strange to me
since they're using the same KEP data, share the same PC clock which
is synced every 12 hours, etc.
Anyone else notice these small differences? None of them have much
effect on actual operation which is governed by the beamwidth of the
antennas (pretty broad), objects
blocking the horizon, etc. but it does make me curious.

I'm using HRD 6.0 SAT Tracker/HRD Rotator as well as SATPC32,
predominately
HRD SAT Tracker.
In fact, I was using SAT Tracker when you and I QSO'd 5/20 on SO-50 .
I use them in conjunction with my Flex 5000A / EA4TX rotator
controller/
G5500 rotator.
I am only using SAT Tracker and SATPC32 for TX/RX Doppler control as
neither
product has adequate support for other Flex 5000 Rig control
functions IMHO
.
I have written software which intercepts CAT commands coming from either
program and I only pass on doppler tuning info through to the Rig.
The same software allows me to do other required Rig control functions:
-TX
-TX/RX calibration for transponder satellites
-RIT
-Transmit power adjust
-Satellite specific controls-TX/RX mode, tones, reset SO-50 timer,
etc.
I also have provided support for my TS-2000 and IC-9100 in the software.
My preference for SAT Tracker is primarily because I like the user
interface
better.
Some caveats on using HRD 6.0 SAT Tracker/HRD Rotator natively with any
supported rig:
HRD Rotator does not play nicely with Rotators with a south stop
(Yaesu-5400), you can make it work, but software azimuth readout is
180 deg
off
HRD SAT Tracker does not support transponders of the "Non-inverting
type"
(like AO-7 mode A)
