Hi,
Since Sept 2009 (when I subscribed to the list) - this thread is most
interesting!
I have great opportunity to help small educational team which is
building 1U cubesat.
And I have to agree 200% with Tony that there is great potential for
ham community in finding space related educational teams in their
countries and help them succeed in their missions.

I just suggest to disconnect civ control and try connecting lvb tracker to
the serial port used for civ.
Another option wold be to try another software, for example hrd has a rotor
control software I use with my lvb tracker. Then try to understand...

Subject: [amsat-bb] LVB Tracker & SAT32PC Help making them play nicely needed
I think Bob, W7LRD, and I have a common block to some of our computer
applications. I am in the process of getting my G-5500 rotor, LVB
Tracker, and IC-910H to all play nicely with one another using SAT32PC
software (v12.8). I am using a Panasonic Toughbook Computer with the
serial port (com4) connected to the ICOM CT-17 level converter for
frequency control of the IC-910. A USB port (com1) is used to talk
with the LVB Tracker. Frequency control works terrific. I cannot make
the rotor control work however. The LVB Tracker manually controls the
rotor just fine. I can also control the rotor position by opening a
terminal window and giving commands(which indicates to me commands are
going down the USB pipe). When I give a park command via SAT32PC,
nothing happens nor does the rotor respond to other movement commands
from the SAT32PC software. I know I must be overlooking something very
simple and perhaps a good nights sleep might help me to resolve my
problem. Can someone share the "secret" of rotor control with me?
Hopefully no secret handshakes or needed. Any help will be sincerely
appreciated.

One can understand the reluctance to allow an explosive kick-motor on a
launch vehicle. But is that the only way?
What about a trebuchet? Springs? Rubber bands? Cylinders of
compressed gas? Gas produced when needed by mixing two stable chemicals
together? A motor that spins up an arm to 'throw' the payload? A
magnetic railgun that fires a slug down out of orbit, resulting in
recoil pushing the satellite up? Or the payload up, while deorbiting
the railgun?
Surely someone smarter than I can come up with a scheme that might
actually work? And someone with a smoother tongue than I can persuade a
university that this is valuable research to be pursued by their space
science department?

We don't need anything so fancy as springs or rubber bands. Electric
propulsion is a mature, safe technology, with many universities and
organizations developing experimental thrusters that need to be tested in
space. Some of them even use solid propellant so no need to do safety
qualification on a high pressure gas cylinder. Nothing at all to explode. That
is how we will get our next HEO satellite.

These days, definitely not, there's a number of different propulsion
ideas being researched, and many of them don't involve explosive chemicals.

Hi Bob,
I don't think we have any "beep boxes" out there. If that is what you call
cubesats, nano and picosats, I would highly discourage you to even look at
them. Now having said that, let's assume you want to receive data from
these satellites, there is NO one tutorial. On the other hand you could
write one :-)
It is all about you doing your own homework, compiling information,
learning along the way and using resources like Mike Rupprecht's beautiful
website: http://www.dk3wn.info/satellites.shtml
for more information.
What you do with the data is totally up to you. Many of us help these teams
and forward telemetry information to them. Some teams have developed
special software to decode the data and allow us to actively monitor the
status of the satellite and any experiments.That's the beauty of this hobby
that we can do some technical stuff, learning about the satellite etc. and
are not reduced to mindless rag chewing with someone who could care less
what my cats name is. Actually I only have a dog
Regarding the keps, maybe you should look up all the great stuff that comes
out of Celestrack and look at:
http://www.celestrak.com/NORAD/elements/cubesat.txt
and that is just one source (Google here I come....)
Hope that helps,
Stefan VE4NSA

Let me add an additional recommendation. Learn to love the soundcard. Go
into the back ACC socket on your radio, find the fixed level AF signal, and
send it over to the line in on your PC soundcard. Now you can copy most of
the digital modes with software like MixW or the programs provided by the
owner of the satellite. SatPC32 set up to Doppler track, and tweaked for
time and freq offsets, is invaluable. When you can decode a CW or AFSK
beacon from AOS to LOS and not touch the VFO, now you've really done
something!

There are several groups currently developing CubeSats with some form of

I'd love to get involved in that, and indeed I think a lot of the
current thread was spawned by a discussion of tracking the F-1 sat.
Unfortunately, there is only a Windows binary available of this
software. I know amateur radio is a technical hobby, but I haven't the
inclination to be a computer nerd as well, and I haven't the time,
inclination or money to buy another computer and a copy of Windows and
all the expensive training courses.
I do wonder if having the telemetry in an unpublished format counts as
using a "secret code"?

Content-Type: text/plain; charset=ISO-8859-1
Hi All,
I've been preparing for the CubeSat release from ISS scheduled for
tomorrow. Hope it happens!!
For my simple brain, I've figured an easy way to get the frequency
tracking/Dopper, etc entered into SatPC32.
First, we can use the ISS Keps for tracking--at least for a few days
probably, until Keps are released by Celestrak, etc. I already have
that working (don't you?). So, no need to do ANYTHING with Keps--just
make sure they are "fresh."
Second, there is the matter of frequencies! So, I entered the
following into my Doppler.SQF file:
ISS,145980.0,437485.0,FM,FM,Nor,0,0,F1 1k2 AFSK packet
ISS,437485.0,145980.0,FM,FM,Nor,0,0,F1 CW telem over FM
ISS,437250.0,145980.0,CW,FM,Nor,0,0,FITSat1 CW telem
ISS,437445.0,145980.0,FM,FM,Nor,0,0,FITSat1 1k2 AFSK packet
ISS,437505.0,145980.0,FM,FM,Nor,0,0,WE WISH 1k2 AFSK packet
Now, all I have to do is track ISS (in normal SatPC32--don't use
SatPC32ISS!), and using the "CAT" menu select the frequency of the
CubeSat I want to listen to. If you look at the text line at the
bottom of the box, you'll see why I put the CubeSat name at the end of
each line above...
Easy to do, no need to worry about "launch Keps", etc. We have them already
:)
Remember, the "upper most" line is one that loads by default. For me,
that's going to be the F1 1k2 AFSK FM packet signal.
Also, after we DO get real Keps--all you have to do is edit the
appropriate ISS with the name of the bird; make sure it's the same
name used in the Keps (or get fancy and use the AmsatNames.SQF file).
Hope that helps some of you...
73,

Looks to me like the program will decode the packets right on the
client software.
Packets copied, decoded. Then, there's always the documentation on
the web. Isn't this what you say isn't there?
What is so secret?

Description

Date time
Date: dd/mm/y: 5/4/3=12 bits

Time: hh/mm/ss: 5/6/6=17 bits

Battery voltage
Battery voltage multiplied by 100, divide by 100 to get actual value
11
3
Solar cells voltage
Solar cells voltage multiplied by 10, divide by 10 to get actual value

Total
112 bits = 14 bytes
Note:
- Temperature reading from sensors, will be added with 100 before
transmission to ensure a positive number so please subtract 100 to get
actual value
- 112 bits, divide to 14 chunks of 8bits, each chunk becomes one byte
- years beginning from 2012, current year = 2012 -> Y = 0
