BID: $ANS-078.01
AMSAT PHASE 3-D INTERNATIONAL SATELLITE BUILDERS MEET IN
MARBURG--PROPELLANT TANKS DELIVERED
During the week of February 10-16, 1994, Dr. Karl Meinzer, DJ4ZC,
AMSAT-DL President and Project Leader for the International AMSAT Phase-3D
satellite, and Werner Haas, DJ5KQ, Vice-President of AMSAT-DL hosted
a working meeting in Marburg, Germany to discuss recent progress on the
project. Agenda items centered primarily around the spacecraft's
electronic systems including the on-board computer (IHU) and RUDAK
systems, as well as the progress now being made by team members on the
spacecraft's other electronic modules.
Also during the meeting, the team took delivery of P3-D's main
propellant tanks. The tanks were manufactured in Russia under contract
from AMSAT-DL and in accordance with AMSAT specifications. Seven tanks
were delivered, although one had been subjected to a destructive pressure
test by its Russian manufacturer.
Not only have all the propellant tank specifications been fully
achieved, but they've actually been significantly surpassed. Each tank
can accommodate almost 50 liters of propellant. Favorable conditions for
the purchase and delivery of these tanks was arranged through the efforts
of AMSAT-UA (Russia). Following a brief inspection, the tanks were
immediately shipped to Orlando, Florida, where integration of the
satellite is now slated to begin this summer.
Dick Jansson, WD4FAB, AMSAT-NA Vice-President for Engineering, also
attended the meeting, principally to discuss various aspects of the
satellite's structure with Dr. Meinzer and Konrad Mueller, DG7FDQ. He
reported on the good progress of the flight model structure's construc-
tion, currently underway at Weber State University in Utah.
Also in attendance were Lyle Johnson, WA7GXD, Peter Guelzow, DB2OS, and
Gerhard Metz, DG2CV. Lyle is known through his work with the Tucson
Amateur Packet Radio (TAPR) group (which he co-founded) as well as for
his work on the Microsats and on the P3-D GPS project. After much
discussion, the team decided to again employ a cable wiring harness
arrangement for Phase 3-D, similar to that used on AO-10 and AO-13,
rather than an AART-based LAN design. However, the team decided to also
fly a CAN bus and DB2OS's experimental LAN controller as part of the
spacecraft's digital (RUDAK) transponder.
In a related decision, the group concluded that the AO-10/AO-13
1802-based Internal Housekeeping Unit (IHU) computer design would still
be adequate for P3-D with some minor modifications. Lyle Johnson
announced his willingness to redesign the IHU and to construct a flight
unit. His offer was greatfully accepted.
Other meeting items centered on P3-D's RUDAK work now being done by
Peter Guelzow, Gerhard Metz, and Dr. Stefan Eckart, DL2MDL. This team
has now decided to build two RUDAKs. The first will be a user-oriented
digital communications module constructed by Lyle Johnson, in close
cooperation with Peter Guelzow. This RUDAK, which has yet to be formally
named, will be the one most P3-D satellite users will operate. A second,
more experimental RUDAK (called RUDAK-E), will be built in Germany. It
will promote experiments with advanced high speed modems, Digital Signal
Processing (DSP) techniques, and new communications protocols.
In a host of other issues, Daniel Orban, ON4AOD, discussed details
of the 24 GHz transmitter. Konrad Hupfer, DJ1EE, reported his progress
in building the 250 watt U-Band (70 cm) final amplifier. Werner Haas
displayed his first flight hardware consisting of two command receivers,
a digital section, and the 70 cm exciter that will drive Konrad's 70 cm
final amplifier. Freddy de Guchteneirie, ON6UG, reported his progress on
the construction of dual V-Band and U-Band receiver "front-ends". Dr.
Matjaz Vidmar, S51MV, reported he has now begun construction of the
HF-Band, C-Band and S-Band receivers. He expects to deliver working
prototypes in May.
While much work still remains to be done, Dr. Meinzer expressed his
approval and sincere thanks to all participants for their superb work and
close cooperation on this vitally important AMSAT international project.
A complete text of this meeting's minutes has been prepared by Peter
Guelzow, and has since been translated by Don Moe, DJ0HC/KE6MN. The text
will be made available to the various international AMSAT Journals for
possible inclusion in their upcoming editions.
[The AMSAT News Service (ANS) would like to thank Peter Guelzow, DB2OS, Don
Moe, DJ0HC/KE6MN, Lyle Johnson, WA7GXD, and Keith Baker, KB1SF, for their
assistance in writing, translating, and formatting the information

ITAMSAT-OSCAR-26 (IO-26) Ground Team Discovers Problem
Starting last week the PSK modulation on the primary trasmitter became more
and more difficult to decode. A residual carrier and lower output power
seem to indicate a failure in the PSK balanced modulator, being worse at
the current low power setting. Increasing the power level makes the de-
modulation better but is not accetable due to power budget constraints.
Ground controllers decided to switch to the secondary PSK trasmitter on
435.822 MHz. The first two passes over Italy confirmed the correct
operation of the spacecraft and WOD are being taken to analize the per-
formance of the satellite in this new configuration. BBS is working as
usual and status bulletin will be uploaded in the next few days.

NASA Info Board BBS at Johnson Space Center as a source of information for
Keplerian elements and SAREX bulletins. This bulletin board system was
operated and maintained by the Public Affairs Office of the Johnson Space
Center and is now no longer operational.
Johnson Space Center Amateur Radio Club is currently seeking a way to get a
small BBS up and running prior to the flight. As soon as a system is
established, an announcement will be issued to promulgate and distribute
the telephone number.

The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
OSCAR status reports. If you have a favorite OSCAR which you work on a
regular basis and would like to contribute to this bulletin, please send
your observations to WD0HHU at his CompuServe address of 70524,2272, on
INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO
area, WD0HHU @ W0LJF.#NECO.CO.USA.NOAM. Also, if you find that the current
set of orbital elements are not generating the correct AOS/LOS times at
your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL. The information you
provide will be of value to all OSCAR enthusiasts.

On or about Feb 28th, Stephen Holmstead (stephen@hpdmlge.boi.hp.com) posted
a fairly comprehensive amateur radio in space FAQ. I wrote him a while
back and made some suggestions, particularly in regard to making it
available via several FTP archives that would be glad to have it, but
haven't heard anything from him since.
Perhaps if you dropped him a line, and asked nicely, he would send you a
copy.

I just found such a FAQ in 4 parts, posted in the last week or so to
the AX.25 packet network here in the US by KD2BD. As is so often the case
with multi-part posts to the ham BBS network only 2 parts made it to my
local BBS. I wrote to KD2BD and I am hoping he will either post it here or
put it on an ftp site.

I was able to find the missing parts on another BBS and I have posted it to
this group as Sat FAQ Answers, the title under which it was posted to the
BBS network.
I presume that further posting is OK with the original authors. What I
posted seems to be a composite of several different articles and it isn't
clear who wrote what or who edited the composite document.
