Amsateers!
I was interested in obtaining a complete set of ARISSat-1 Keps for
analysis. I requested them from the AFSPC and received permission to
place them in the public domain. See my blog for the complete list

I have an old GPS unit, a Magellan explorist 210. It's fairly accurate
determining position. After it has acquired about eight to ten satellites
the position error averages between 20 to 35 feet. Now the question, the
other day I was looking at one of the information pages the unit can
display and on it, it gives the time in UTC. Just for fun I thought I would
see how close the time was to WWV. I was surprised to see the unit was
between one to four seconds off over various tests compared to WWV. IS
this typical of all GPS units or do some display the time of day more
accurately?

Check out http://gpsinformation.net/main/gpstime.htm
The short answer is, the internal GPS clock for position is very
accurate or it could not make to calculations needed as to where you
are at, but there are many factors
that might delay what time it gives to you on a display panel or through
a serial cable.

I'm not sure about GPS,but I have noticed that the clock on our cable box is
off by up to 4 seconds at times.Customer service was not aware or concerned
when I let them know.

You will find that most handheld GPS receivers sold for casual use have a
displayed time error that varies from 0 to 4 seconds. The receiver software
was designed with an emphasis on computing position and performing other
tasks, such as routing, more than on displaying time. Hence the presentation
of time is some times delayed. If time is of higher importance, then a
specialized GPS timing receiver is needed. Look for one that outputs a 1PPS
(one pulse per second) signal and comes with timing software.

I had this question posted to me, and I can't seem to figure out if it is
possible.

I know that the rotor interface unit, ERC can be limited via it's service
tool software, but I wasn't sure how SatPC32 would react to the interface
unit limiting it.

Scott,
No problem, unless you want to run it in full screen or graphics mode. WIN7
does not fully support DOS programs in full screen mode. However, there are
a couple of ways around that. You can run it in a virtual XP machine. I
have WIN7 Pro, and it is a free download.
However, there is a simpler method. There is a program called DOSBox which
is intended to run really old legacy games. It works perfectly with ITrack,
and makes a much smaller footprint on your machine.
http://www.dosbox.com/
Even though I have the virtual XP machine, I prefer to use the DOSbox
version. With a little obvious tweaking of the configuration, it will come
up as before.
73s,
Alan

I'll take a shot at this:
You can, by SatPC32 settings, limit the movement to 90 deg elevation.
That will prevent what many of us call "180 flip mode" or some
variant.
Now to limit to 85 deg?? I bet if you use a setting of either time
interval (increase it...) or Position change (increase it) you'll end
skipping most of the 85-90 operations, most of the time... Is it
absolute? Probably not.
Now, if the controller is configured to only go to 85 deg, I suspect
it would ignore any values above 85...so just rely on the
hardware/controller and not SatPC32.
Best I can offer up...

Interesting question, Vince...am sure someone on here will be able to
answer it. I know at one time the civilian population was restricted
from the most accurate location, and as I also remember the military
accuracy was within a centimeter if several observations were
taken...Nice to see your smiling face on here, my friend...
Anyone?
