Thank you David for the return,...
Detailed information of the orientation systems and positioning is what I
look for,
but it is reasonable that some information is reserved.
I will try to find all the information that is possible to help me to guide
my own experiments about this matter..
Thank you again

Hi all,...
I want to learn about horizon detection, orientation and automatic

Can somebody guide my search of information about this topic?

CX2AN
Attitude control is usually done in LEO with "magnetorquer coils", or
"reaction wheels" or "attitude thrusters"
Attitude determination can be done in several ways By "sun sensor"
"horizon sensor" "Star tracker" or by comparing the detected magnetic field
on the satellite against a model of the earths magnetic field stored in
memory.
If you search for the above topics you will find papers from teams who
have implemented satellite control using these methods. Of course the
computer algorithms to process the data collected and calculate attitude is
complex.
You will not get detailed information from the USA due to their ITAR laws.

Hi all,
My Gulf antenna arrived last week and togther with my recently aquired
FT-736 I should be up and running within the month.
My initial reason for building my satellite station was to receive and
decode telemetry from the sats, hoping to monitor their condition over a
period of time. I realise that some transmit TLM via morse, some via AX25,
and some via 96K packet.
What would be the best sat to start with, especially AX25? - Does AO51 send
TLM all the time or only over the USA? What resource is the best for
reading? Does the F&-736 need modifying for high speed packet reception?
Many thanks for any help.

Peter,
AO-51 data is not limited to the US normally, but is sometimes off due to
the operating mode. One of the AO-51 pages gives a URL for the TLM program,
as well as some other useful information:
http://www.amsat.org/amsat-new/echo/
Here is a page which includes info on modifying the FT-736 for 9600 baud:
http://www.amsat.org/amsat/articles/w6shp/rxtxmods.html
I am certain you will get some good recommendations for starter satellites,
but satellite status pages will give you some idea what is available:

Does ITAR laws only apply for US satellites or also for satellites of other

Does US apply restrictions in this topic for all the satellites in orbit?

ITAR rules and restrictions apply to anyone exporting ITAR controlled
information from the United States. It does not matter if the information
is in regard to other country technology or where it came from. ITAR
restricts me from discussing Soviet, Chinese, English, Iranian, or US
satellite technology. There are exceptions but I would advise you to read
the ITAR (22 CFR 120-130), it is readily available. ITAR does not control
exports from other countries by non-US persons. They have their own laws
and regulations.

Well, I am understanding like this works...
now then, in the case of radioamateurs of other countries that they build
their satellites,
in some cases in collaboration with Amsat, like the technology transfer
works?

Four CubeSats in Japan are planning to launch on 17 May 2010
together with PLANET-C which belongs to JAXA by H-IIA rocket.
Launch date, 17 May 2010
Launch time, 21:44:14UTC
Launch site, Tanegashima Space Center in Japan
Three of the CubeSats, Negai*", WASEDA-SAT2, KSAT, being launched by
the H-IIA rocket on May 17 will be dropped off into a low earth orbit
but UNITEC-1 will continue following the JAXA's Venus Climate Orbiter
PLANET-C / AKATSUKI on its journey to Venus.

When you have some experience with your Gulf Alpha I hope to hear
how it is doing. I really love the design and the way they are build
but have no idea how the perform.

I decode also a lot of telemetry from the following sats:
DO-64: Via RASCAL that can be downloaded via there website www.delfic3.nl
FO-29: Morse
HO-68: Morse
RS-30: Morse
RS-38: Morse
etc etc
Only the sats that use 9k6 are out of my league but that will change in the
next couple of months

Hi Peter,
Here is a short overview what you can actually hear if you are interested in
to collect telemetry:
OSCAR IO-26 1k2 BPSK, sporadic 5 bursts
Fuji OSCAR FO-29 CW
AMRAD OSCAR AO-27 1k2 AFSK scheduled
GURWIN OSCAR GO-32 9k6 FSK 1 burst every 30 sec
(weak)
NavSat OSCAR 44 1k2 AFSK only in sunlight 1 burst
every 1 min
AMSAT OSCAR-E AO-51 9k6 FSK scheduled
KKS-1 CW
STARS (Mother) CW
PRISM CW
HOPE OSCAR HO-68 CW
CubeSat OSCAR CO-57 (XI-IV) CW
CubeSat OSCAR CO-58 (XI-V) CW
CUBESAT OSCAR CO-55 (CUTE-I) CW
CUBESAT OSCAR CO-65 (CUTE1.7+APD II) CW
COMPASS-1 CW beacon every 4 min
SEEDS CW
DELFI-C3 1k2 BPSK only in sunlight
SwissCube CW
RS-22 CW
RS-30 CW
GeneSat-1 1k2 AFSK
You can see - it's the best way to start with CW satellites. The most of
them are sending telemetry continuously.

Joel,
As put before, we are the only organization that directly supports Amateur
Radio Satellites. Everything we do supports this effort. Those that use
the satellites for their fun and DO NOT belong to AMSAT are defeating this
effort. Satellites don't magically appear for everyone's benefit.
Whenever I give a talk, my bottom line is "I work for donations!" We are
striving for the best bang for the buck and putting a satellite in orbit
that gives back the most in returns.
Pass the hat and pass the solar panels!

AMSAT-BB,
I realize what I'm going to get by asking this... If you were giving a
presentation to amateur radio operators who know little or nothing of AMSAT,
what would you list as some of the benefits of being a member of AMSAT?
What would be the single most important reason?
73,
Joel, W4JBB

East Coast APRS Satellite Launch 11 March!
You will be able to see it too over most of the mid-atlantic. I don't see a
launch time or any other info yet. Here is what I have received:
-----------------------------------------------------
A sounding rocket with amateur satellite operating on 144.39 MHZ APRS will
rise to 100 miles or so for an 8 minute mission. The rocket (I think) is
the Hall 12.067.
The payload is called SOCEM/ADAMASat. There is a computer program and GUI
to interface to your PC so you can grab the telemetry live. It is on:
http://ssl.engr.uky.edu/adamasat_free_gui.exe
It's a one shot deal, so I'm gonna have a backup TNC and
HYPERTERM collecting everything.
ADAMASat is the Antenna Deployment and Mono-filament Actuator Satellite.
It's a 2U CubeSat designed by Kentucky Space as part of SOCEM, the
Sub-Orbital CubeSat Experimental Mission.
ADAMASat, which is scheduled to launch on Hall 12.067 out of Wallops Flight
Facility on 11 March, will fly in space for roughly 8 minutes performing an
engineering experiment and transmitting data down to Earth via APRS packets.
More information on ADAMASat is available at
http://ssl.engr.uky.edu/suborbital/adamasat Kentucky Space is hereby
releasing to the AMSAT-NA community the ADAMASat FREE GUI, a free 32-bit
Windows binary for amateur radio operators in the Eastern United States who
are interested in tracking ADAMASat on its launch day. The GUI is a
standalone application and upon opening it on his/her computer, the HAM will
be greeted with a popup window which explains the steps required to track
the payload.
All that is needed is a Windows machine, a radio and TNC which can receive
on 144.390 MHz, a serial or USB cable, and a suitable location. The GUI
parses the APRS packets as they are received, graphing temperatures on-board
the payload and reporting status of the mission in real-time. It also
includes instructions on e-mailing the packet log to Kentucky Space to aid
in post-processing, and a built-in aggregator for the official ADAMASat
Twitter RSS feed.
Disclaimer: Kentucky Space provides the GUI "as is" without warranties of
any kind, and shall not incur any liability for any damages connected to the
use of the GUI.

FCC to Permit Rescue Radio Robot in the 430 to 450 MHz Band
Reports initially carried in the February 26, 2010 edition of Amateur
Radio NewslineT Report 1698, and on the QRZ.com website say the FCC
has issued a waiver of the Part 90 rules to permit a company called
Reconrobotics Incorporated to sell a remote controlled security robot
that will operate in the 430 to 448 MHz band. This is spectrum that
is primary to the Federal Radiolocation Service but also encompasses
the Amateur Service weak signal, satellite and repeater subbands.
The waiver permits Reconrobitics to manufacture and sell a device
called the Recon Scout. This is described as a device designed for
state and local law enforcement and firefighting agencies, and secur-
ity personnel in critical infrastructure industries. The Recon Scout
can be thrown, dropped, or launched into potentially hazardous areas
and can provide real-time video to an operator located a safe dis-
tance away. Typical applications will include such things as checking
a building prior to forced entry, searching vehicle undercarriages
for explosives and searching for survivors in a burning structure.
The Recon Scout transmits the analog video signal to the operator on
one of three six megahertz channels. These are 430 to 436 MHz, 436
to 442 MHz, and 442 to 448 MHz. Reconrobotics says that multiple
channels are necessary in order to avoid interference during incidents
where multiple Recon Scouts are in use, but that such situations
should be rare.
The company's now approved proposal is that the first unit sold to a
responding organization would operate on 442 to 448 MHz. That happens
to be where thousands of ham radio repeaters operate. The 436 to
442 MHz version being sold only to entities that already own the 442
to 448 MHz version, and the 430 to 436 MHz version being sold only to
entities that already own both of the others.
In approving the waiver, the FCC told Reconrobotics the Recon Scout
will have to operate on a secondary basis where it cannot cause inter-
ference and is not protected from interference to all Federal users
and licensed non-Federal users including radio amateurs. The FCC
also warned prospective users that operation of the Recon Scout in
an unauthorized manner will subject licensees to Commission enforce-
ment action and license revocation. It also said that widespread
improper use of the device could lead the Commission to stop grant-
ing or renewing Recon Scout authorizations.

SK: Dave Toth, VE3GYQ
AMSAT received the sad news of the passing of a friend this week
noting the passing of Dr David Toth, VE3GYQ. Dave was the President
Emeritus of Tucson Amateur Packet Radio (TAPR) Group. He was an
early member of TAPR, a long time supporter of AMSAT and he gave
of his time and talents to promote technical endeavors in Amateur
Radio. Former AMSAT President Tom Clark, K3IO remembered Dave,
"He was always a friend of AMSAT, giving up personal vacations to
help with the integration of AO-40 in Orlando. For many years, he
was the glue that held TAPR together."
Former AMSAT Board Member, Bob McGwier, N4HY recalled that, "Dave
was an important player in the earliest days of packet radio in that
he helped promote packet and supported it with on the air hardware.
As a board member and President of TAPR, he helped TAPR become the
principal support for Open HPSDR, a project to promote the development
of hardware and software for software defined radio use by Amateur
Radio. He will be sorely missed by all who knew him."
Dr. Toth graduated from the University of Western Ontario Medical
School in 1978. He practiced family medicine in London, Ontario but
moved to the U.S. in 1993 to began a career in emergency medicine.
He was a partner of Premier Health Care Services, in Dayton, Ohio,
and worked at Lima Memorial Health System and St. Rita's Medical
Center until the time of his illness.

Next week, March 14th, our semi-annual time change will occur.
And of course, do we gain or loose an hour? The words Spring ahead and Fall
back should come to mind as this is the rule. More modern Atomic Clocks (as
they are called)
Set themselves without any manual adjustments. I had a clock that was pre
programmed for earlier
DST changes and sent me to work late one Monday morning. Get out your
pencils and mark your calendar
For this event. I'm sure the News media will advise you for several days
prior to this required
Adjustment to happen, but, someone will not get the word. Please tell that
person.
Thank goodness GMT (UTC) stays the same no matter what time of the year it
is. Computers too are
Pre programmed but satellite program users should make sure time was
corrected properly. We
Wouldn't want you to miss that Sat QSO you planned for all week. Don't
forget the 1.26 micro second
Adjustment that the Earthquake in Chile has created.

AO-51 Survives Close Encounter With FORMOSAT-3
AMSAT-NA VP Operations, Drew KO4MA, received notification from the
US Joint Space Operations Center, located at Vandenberg Air Force
Base, California on Sunday, February 28 warning that AO-51 would
have a close approach to another satellite, FORMOSAT 3-D, on Monday
at 1056 UTC. This occurred over the Eastern US, with many stations
on hand capable of receiving telemetry from AO-51 before and after
the near miss. Drew said, "The predicted miss distance was 953 meters,
which is over 3000 feet overall but the radial difference between the
two orbits was only 39 meters."
Steve, W3HF noted, "Given the orbital uncertanties of both satellites,
an orbit separated by only 39 meters could mean that distance may become
eaten up rather quickly!"
In preparation for the close encounter, Drew shut off the S band tran-
smitter and turned on the digital downlink at 2 watts, with telemetry
transmitted every 5 seconds. The next morning, on March 1, Drew was able
to post a message that AO-51 was alive and well, "It looks like we are
fine. A second warning email this morning from the Air Force called it
even closer, but everything was working at LOS this pass."
FORMOSAT-3 is a constellation of satellites launched on April 15, 2006.
It is a joint U.S.-Taiwanese project with major participants including
the University Corporation for Atmospheric Research (UCAR), the National
Science Foundation, the Naval Research Laboratory (NRL), the Air Force
Research Laboratory (AFRL) on the U.S. side and the National Space
Organization (NSPO) on the Taiwanese side.
