AMSAT Introduces Team Namaste at Dayton Hamvention

AMSAT News Service Bulletin 138.01
From AMSAT HQ SILVER SPRING, MD.
May 18, 2008
To All RADIO AMATEURS
BID: $ANS-138.01

Team Namaste, a new AMSAT engineering team, was introduced at the
Dayton Hamvention held over May 16-18. AMSAT's Eagle and the
Intelsat Phase IV ride-share project will include the Advanced
Communications Package (ACP) supporting digital communications
with a 5.6 GHz uplink and 3.4 GHz downlink.

Team Namaste includes the ACP Ground Segment led by Michelle, W5NYV
and the ACP Satellite Segment led by Matt, N2MJI.

Michelle described the ground segment, "Namaste is the effort to
develop a microwave band, digital signal capable earth station
attainable by the average ham so users can immediately take advantage
of the audio, digital messaging, and video services our new new sat-
ellites will provide."

Two key user audiences are the target of the Namaste earth station.
Michelle describes the user base, "First we want to excite amateur
radio operators who want to have fun using microwave bands to talk
through a satellite employing digital communications techniques.
Second, we want to serve emergency communications operators who need
a reliable, infrastructure-independent system in order to get their
work done."

The Ground Segment and Satellite Segment Teams are developing an RF
link budget and system configuration which a reasonably priced ama-
teur radio transceiver can attain. No commercial amateur radio gear
exists for the GHz-frequency range and digital communication link
for the new mode on AMSAT high orbit satellites.

Antenna configuration and available power are limited on the satellite
platform depending upon solar cells and batteries. Given the modern
reality of CC&R's and antenna restrictions in many communities the
baseline antenna at the amateur station is currently specified as
a half-meter dish. This is the same type and size of dish many homes
use for satellite television such as DirecTV.

Planning for the ACP includes 20 watts RF power with 18dB antenna gain
at the spacecraft. The ground segment rule of thumb at present esti-
mates 10 watts of transmitter power with the half-meter dish is needed.
Further radio link budget and RF exposure safety issues are also being
investigated.

AMSAT welcomes Team Namaste, leading the way to an exciting future of
Amateur Radio in Space. Questions and comments can be sent via e-mail
to . Team Namaste has a web page at:

BID: $ANS-138.02

Bill Tynan, W3XO issued the following statement on behalf of the AMSAT
Board of Directors this week:

By the authority vested in me by the AMSAT-NA President, I am pleased
to issue an OSCAR number for the amateur radio satellite, Delfi C-3.

As attested to in a communication to the AMSAT-NA Board of Directors
dated 8 May, 2008, from Wolter Jan Ubbels, the spacecraft's Project
Manager; Delfi C-3 was successfully launched 28 April, 2008 from India
aboard a Polar launch vehicle. Mr. Ubbels also states that the satellite
was successfully commissioned and is currently transmitting telemetry
on the 2 meter amateur band. In addition to its 2 meter downlink, Delfi
C-3 has an uplink on the 70 cm band.

According to Mr. Ubbels, this newest amateur satellite was developed
by a team of some 60 students and facility members in the fields of
Aerospace Engineering, Electrical Engineering, Mathematics and Computer
Science from various polytechnic schools in The Netherlands. Further,
he states that Delfi C-3 carries 2 experiments, one involving thin film
solar cells developed by Dutch Space and the other, an Autonomous Wire-
less Sun Sensor from the Dutch Government Research Institute (TNO).

Mr. Ubbels' letter says that Delfi C-3 has been duly coordinated through
the Region 1 IARU representative, Mr. Graham Shirville, G3VZV, and that
the satellite meets all of the criteria necessary to be issued an OSCAR
number.

In response to the information provided by Mr. Ubbels, I hereby issue
the designation Delfi-C3 OSCAR-64 or Dutch OSCAR-64. The shortened ver-
sion of either of these two designation would, of course, be, DO-64.

AMSAT-NA is pleased to welcome DO-64 into the family of amateur Radio
satellites. We are hopeful that it will fulfill its intended mission of
furthering education and increasing interest in the Amateur Radio space
program. We congratulate all of those responsible for designing, building,
testing and launching this new Amateur Radio satellite and look forward
to its long and productive life.

AMSAT at Dayton - First Report

AMSAT News Service Bulletin 138.03
From AMSAT HQ SILVER SPRING, MD.
May 18, 2008
To All RADIO AMATEURS
BID: $ANS-138.03

The AMSAT booth at the Dayton Hamvention included the first stages
of the full-scale engineering unit of the Eagle satellite structure.
This consists of the inner 4 honeycomb panels where electronics are
mounted, along with four channels and two electronics boxes. The half-
scale model of Eagle was also on display. After the Hamvention the
Eagle engineering unit will return to the AMSAT Maryland Lab for
further development, integration, and testing.

Radio amateurs were able to get a taste of satellite operations at
the live satellite demos. Using the callsign W5IU the demo team was
on-the-air via AO-7, AO-16, AO-27, AO-51, and VO-52 on Friday, Sat-
urday, and Sunday.

Tom Clark, K3IO gave a presentation discussing the highlights of
AMSAT's technical achievement and plans at the ARRL TTF Forum. The
AMSAT forum provided updates on Eagle and Intelsat. More information
will be coming in future weeks via ANS and the AMSAT Journal.

AMSAT Engineering representatives were on hand to show off and discuss
project status for the ACP, Eagle, Phase IV, P3E, SuitSat-2, and dig-
ital encoding.

The combined AMSAT/TAPR Banquet was one of the more popular events of
the weekend. Pictures and more stories to follow when they are ready.

The Spring 2008 issue of CQ-VHF magazine, planned to be available at
the Hamvention, featured AMSAT in three articles. Lou W5DID & JoAnne
K9JKM had an article covering SuitSat-2. Bob KF4KSS & JC W3JCT had
an article about AMSAT's new lab, and Keith W5IU wrote a column of
amateur radio in space history and AMSAT's history.

AO-16 Operations Update

AMSAT News Service Bulletin 138.04
From AMSAT HQ SILVER SPRING, MD.
May 18, 2008
To All RADIO AMATEURS
BID: $ANS-138.04

The AO-16 satellite has undergone a few periods of turning off with
subsequent restarts ensuring operation for varying periods of time.

Mark, N8MH, Control Operator turned AO-16 ON in voice mode to suppot
a Scouting Special Events Station. The output power was reduced slight-
ly in an attempt to conserve power in the event that batteries or the
solar cells were having problems.

George, KA3HSW, operating from the Scouting Event wrote, "Many thanks
to Mark for making AO-16 available during the K9BSA Scout-O-Rama
demonstration yesterday, and MANY, MANY thanks for "advertising" that our
station was there on the 1950Z pass... we worked quite a number of
stations, thanks in large part to Mark's announcement on the bird."

In response to observing stations around the world reporting AO-16
was turned off again Mark provided the latest information, "AO-16
continues to exhibit difficulty in keeping the transmitter turned ON.
The last few days I have turned it ON as my schedule permits, only
to see it turn itself OFF after a short time (sometimes minutes,
other times a few hours). So, it hasn't been turned ON much over
the last several days. It is looking less likely to be a power budget
issue, and more likely that there is something going on with the
hardware in the spacecraft; but this is still speculation. Time
will tell. I wish the news was better!"

If you hear AO-16 in voice mode, free to use it. If you hear it
"hummmming" in digital mode, please do not transmit to the satellite.

AO-16 Uplink: 145.920 MHz FM
AO-16 Downlink: 437.0260 MHz DSB (LSB and USB)

1. Upcoming School Contact

Delta Researchers Schools 2008, Space Expo in Noordwijk, the
Netherlands, has been scheduled for an ARISS contact via tele-
bridge station WH6PN in Hawaii. The contact will take place on
Friday, May 23 at 15:01 UTC. Twelve Dutch primary schools which
participate in the Delta-project will be represented at Space Expo.
The project is a cooperation of the Dutch ministry of Education,
Culture and Science, the European Space Agency (ESA) and NASA.
The schools participating in the project use the themes of space
and space exploration to teach science and technology. Three chil-
dren (ages 7 - 12) from each school will be present.

2. Armada Area Schools - ARISS Contact Postponed

The ARISS contact which was scheduled with Armada area schools in
Michigan on May 9 was postponed due to crew scheduling issues. It
will be rescheduled in the fall. In place of the May 9 contact, the
Teaching From Space Office at Johnson Space Center arranged a tele-
conference between the Armada students and astronaut Bill McArthur
in Houston Texas. Bill spent several minutes talking about the Inter-
national Space Station and answered in detail 15 student questions.
There were approximately 550 participants present at the school. The
Teaching From Space Office also sent an educational resource package
to the school which included seeds that were flown in space. The Armada
schools are looking forward to a direct ARISS contact in the fall.

3. ARISS Founder Ron Parise Passes on

Astronaut Ron Parise, WA4SIR, passed away on Friday, May 9. Ron was
a key player in the development of the ARISS program and a strong
supporter of educational outreach activities. He spoke with hundreds
of hams on the ground during his Shuttle flights STS-35 and STS-67 and
was the first to operate packet radio in orbit. He was instrumental in
developing both the ISS Ham radio systems currently onboard the ISS
and the telebridge station concept with the specific purpose of encour-
aging students to pursue studies in technical fields.
