I have an SASI Sat Tracker unit that was once used to interface with my
G5400B rotator controller. I believe, based on my notes, that this device is
compatible with Nova for Windows software for automatic rotator control.
Please correct me if I am wrong. I am hoping to find someone who still has
Nova for Windows gathering dust and is willing to part with it (in other
words, has moved on beyond it). Without this S/W my belief is that the SASI
tracker is of lilttle use to me.Your help would be appreciated.

Nice article. A couple questions:
1- Can one run both tracking (B5400) and tuning with SATPC32?
2- I didn't know that Yaesu needed a CAT converter to RS232.
The K3 has a RS232 port so easy to connect. But I will have to get
into SATPC32 to see if it will support control of the K3.
3. Does SATPC32 interface with the Unitrac2000.
I am running winXP with a computer that has a com port and USB.

Hi Ed,
Sure -- SatPC32 runs both tracking and tuning just fine. I don't list
it in my article (referenced earlier) but other sections of my blog
show how I've connected up a G5500 rotator. Having SatPC32 controll
both the dopper tuning and the tracking is awesome -- it's a great
program, well worth it.
Some Yaesu's need the CAT convertor -- specifically the FT817, FT857,
and FT897. You can either do a USB --> Serial convertor, then a
Serial --> CAT convertor, or you can use one of the all-in-one cables
that go right from USB to CAT. I've used both (one of each for
portable) and they work fine.
SatPC32 and Unitrac? Not sure, maybe someone else knows...

I downloaded the program just ignore the safety warning certificate from
Firefox and you will be able to reach the download page.
You can look at a screen dump pictures of ARISSat-1 BPSK1000 software and

Celestial mechanics is a brain teaser...but most of what has been said here
is more or less correct. The trick is to realize that the ONLY orbit where
the velocities (and "energy") are "constant" is a perfectly circular
one...and that really doesnt happen but in theory (although some come very
close)...a retrograde manuever will remove ARISSsat from the proximity of
ISS very very quickly. Robert G. Oler WB5MZO

orbit, slightly, and also make it a bit elliptical (up and down). The
higher orbit makes the satellite go behind the ISS, but the elliptical shape
also means that the orbits will cross every orbit (but out of phase, so they
won't be at the same place when they do). But, then as the ARISSat orbit
decays, they will get closer and closer, potentially getting back to the
same place. Not good, either.

the orbit (and make it a bit elliptical), and initially the apogee of the
orbit will intersect that of the ISS. Being in a lower orbit, ARISSat will
move ahead of the ISS, and over time, as the ARISSat orbit decays, the two
will diverge even farther. So, this is the safest.

Hi Jim,

also flubbed it. Here is the corrected information:
