JAMSAT Announces Amateur Satellite to Venus

AMSAT has received news from Japan that JARL/JAMSAT are collaborating
with the Japanese University Space Engineering Consortium (UNISEC) to
send an amateur radio payload into a Venus transfer orbit with the pri-
mary JAXA Planet-C Venus Orbiter mission planned for May, 2010.

UNITEC-1, developed by the teams who have already launched cubesats
such as University of Tokyo's XI-IV, XI-V, and Tokyo Institute of Tech-
nology's CUTE-1, CUTE-1.7+APD has the following engineering missions:

1. Onboard computers developed by several universities will be tested
    in the harsh space environment in the form of a competition; i.e.,
    the computer which can survive to the last in the radiation-rich
    deep space environment will win the competition.

2. Technologies to receive and decode very weak and low bit rate
    signal coming from deep space will be developed and tested.

3. Technologies to estimate orbit and signal Doppler shift of the
    satellite based on the received RF signal will be developed and
    tested.  These technologies are essential for tracking and receiv-
    ing signals from a satellite in deep space.

The UNITEC-1 team invites the support of amateur radio amateurs all
around the world to participate in the receiving and data capture ex-
periments in objectives 2 and 3, above.  They note that amateur radio
operators working as individuals or in groups develop stations and
techniques to relay their received signal reports and data to the
UNITEC-1 control station. This is also a unique opportunity to pro-
pose amateur experiments or competitions to the satellite team.

UNITEC-1 will transmit a signal consisting of a CW beacon of about
1 bps speed. One experiment requiring the participation of several
amateur radio earth stations would include the development of infer-
eometric techniques to combine the received signals from several
antennae to improve the received S/N ratio from the spacecraft out-
bound from earth.

The UNITEC-1 website provides the latest mission information (such as
orbit parameters, data formats and current status). UNITEC-1 will be
the first university developed interplanetary satellite as well as the
first amateur interplanetary satellite. The team sincerely hopes that
UNITEC-1 will provide unique and exciting opportunity for the radio
amateurs all over the world to enjoy reception of signals from deep
space.

Latest News From the AMSAT-UK/ESEO Project

AMSAT-UK reports it is getting ready to support the European
Student Earth Orbiter (ESEO) with on board transponder and
telemetry equipment. AMSAT will provide some of the satellite
communication functions and enable the ESEO flight operations
to access the Global Educational Network for Satellite Operations
(GENSO) and the worldwide amateur radio network.

The ESEO project is studying the implementation of some important
changes in requirements, in order to comply better with launch
opportunities to fly the satellite to low Earth orbit as a secondary
payload on one of the VEGA qualification flights. This essentially
involves a redesign to reduce the dry mass of the satellite and its
payload from about 120 kg (as per Phase B1) to a target of 75 kg,
while at the same time maintaining an architecture that will support
the key systems and functions of the satellite.

The development team consisting of 10 different universities and
AMSAT completed a workshop in December, 2008 which completed a
preliminary definition of the new ESEO configuration and the def-
inition of the corresponding preliminary system budgets (mass,
power, data links), as well as the identification of potentially
critical areas that will require further attention at a later date.

The Amateur Radio Payload is planned to include:

+ U/S Transponder - either FM voice and/or linear/with DSP
+ U/V Transponder - linear with DSP
+ C-Band beacon

Additionally, telemetry will be provided in a number of different
formats. The latest news can be found on the ESA Education website.

ISS Ops

AMSAT News Service Bulletin 004.04
   From AMSAT HQ SILVER SPRING, MD.

BID: $ANS-004.04

The ISS operated with an uplink 0f 1269.650 MHz and downlink of
145.800 MHz. There have been many QSO's via this repeater mode
along with interesting reports about doppler effects, signal
strength etc.  Many have been posting reception reports and comments
after successful contacts on the AMSAT-BB e-mail list for those of
us to enjoy that may not have the equipment to operate with. (Time
has been my bandit. ed. note)

Mike, N1JEZ reported, "I got on the ISS Repeater this morning during
the 1127 UTC pass here in  Vermont FN34im. I took the opportunity to
play with doppler/power/antenna alignment/modulation etc. As suspected,
everything needs to be pretty much right on for good access. By paying
close attention to AZ/El and Doppler, I was able to hold the repeater
down to less than 5 degree El. Even at my power level, being 2-3 kHz
off seemed to be the maximum error on doppler. Power here was set at
approximately 5 kW EIRP. I did drop 10 dB and still got in as the ISS
passed overhead. My full power setup here includes 80 watts in the
shack to a 55 element 1269 MHz Directive Systems loop yagi. My trans-
mission line is 75' of 7/8" hardline."

Alan, WA4SCA said, "I have about 2500 watts EIRP on L-Band, minus some
attenuation from trees, and could only bring it up above 45 degrees.
the limiting factor seemed to be having enough radiated power to break
the squelch. I determined that the uplink frequency needs to be properly
centered.  On AO-51 I can go ± 5 kHz and still get it, whereas with
the ISS I got nothing, even around TCA.  ± 3 kHz is probably more
like it, and of course depends on your power."

Clare, VE3NPC wrote, "NA1SS heard my reply to his CQ and congratulated
me on being the first station heard via L-band but unfortunately he
didn't get my call right and I wasnt able to get in again on that
pass." He was able to work N1JEZ and other stations on later passes.

Frank, IW4DVZ running and FT-736R + PA output of 40 watts on L-Band FM
into antenna consisting 2x35 elements linear polarization and manual
doppler compensation worked Fer, IW1DTU.  Fer was running a TS-790
with 60 watts output into 55 element yagi on L-Band.

David, G8OQW running an Icom 910 into a horizontal 19 element yagi on
a tripod mount on his patio reported, "At 60 degrees elevation I just
made it in but very briefly and with a very scratchy signal. On Jan-
uary 1 I had and excellent pass, accessed repeater at best range yet,
750Km still using only 170w max ERP from tripod mounted 19 element
horizontal yagi."

Jeff, K7WIN reported working Ron, N6PAA on January 1, "I could hear
you for over 2 minutes prior to our QSO and our QSO lasted just about
2 minutes. I couldn't get in until ISS was above 15 degrees as I only
have 10 watts on L Band."

All,

Happy New Year!!

The ARISS team hopes you are all enjoying the diverse amateur radio
opportunities that have occurred on the ISS over the past several weeks.
  We want to thank Mike Fincke, KE5AIT, for his outstanding support to
the ISS Ham Radio community.  His efforts have been phenomenal!

This e-mail provides an update of the ARISS special event opportunities
for the next two weeks.  As previously mentioned, the ARISS team is
currently celebrating 25 years of amateur radio operations from space.

This past week, the ISS Ham radio system was configured in the L/V
crossband repeater mode.  This configuration will continue through to
Saturday when a school contact is scheduled around 10:35 UTC.  After the
school contact on Saturday January 3, it is our plans to have Mike
Fincke reconfigure the radio to support V/U crossband repeater
operations.  As a reminder, that configuration has a 145.99 MHz uplink
frequency including PL tone of 67.0 and a 437.80 MHz downlink frequency.
  All repeater operations are being performed in low power (5 W) mode.
It is our intent to keep the repeater active in this configuration for 2
weeks (through January 17).

We are also considering follow-on experimental operations of the 9600
baud packet radio system and the L/V crossband repeater.  Stay tuned for
future updates.

As a reminder, a special certificate is being developed for those who
communicate with the ISS.  This certificate will be awarded to those
that have had 2 way communications with the ISS on Voice, Packet (APRS),
or through the voice repeater.  And those that have heard the ISS from
space in any of the ARISS operations modes (Voice, SSTV, School Contact,
Voice Repeater, Digital).  Valid dates to qualify for certificate:
November 30 to January 15.

To receive the certificate:
A) Please note on your QSL the ARISS mode of operation (e.g. SSTV,
voice, school, etc) and whether the contact with you was 1 way (receive
only) or 2 way.
B) Send your SASE to the normal ARISS QSL volunteer distributor in your
area of the world.
C) On the outside of the QSL envelope, please include the words "25th
Anniversary Certificate"
D) Make sure your envelope is big enough to accept an 8.5 by 11 inch
certificate and includes the proper postage.
E) Go to www.ariss.org if you do not know where to send your QSL and
please use one of the standard international QSL distributors that are
noted on the Web page.

Important note:  We will be sending your certificate to the volunteer
distributors in bulk AFTER the event is over.  (This saves workload and
money).  So do not expect to see it until 1-2 months after the event
closes on January 15.

We would like to remind everyone that ISS flight requirements related to
EVA and vehicle activity may require the radio to be off for some
portion of this schedule. And school contacts and general QSO
opportunities by the crew will also preempt this schedule for short
periods of time.  (But remember that if you hear these, you still
qualify for a commemorative certificate).

Continue to enjoy the ARISS ops on ISS in 2009!
