The ARISS Status Report this week says two more astronauts have
received their Amateur Radio Licenses.

Ron Garan of Expedition 27 completed testing for his amateur radio
license and has been issued KF5GPO.

Kevin Ford has been issued the callsign of KF5GPP and is currently
training for a future expedition crew assignment.

Andre Kuipers had an ISS amateur radio review session on May 4 in
preparation for his tour on the ISS as part of the Expedition 30 crew.
Don Pettit will join him as part of that crew.

IARU Publishes Revised Requirements for the Amateur Satellite Service

BID: $ANS-136.04

In preparation for frequency allocation negotiations the IARU has pub-
lished a full specification at http://www.iaru.org/ac-09spec.pdf

Items of interest to the Amateur Satellite Service include:

+ An allocation for the Amateur Satellite Service is sought in the
50-54 MHz range to bridge the gap between 28 MHz and 144 MHz.

+ The Amateur Service requires retention of the existing allocations
in the 420-450 MHz band and opposes new uses by other services or
low-power devices except where sharing or compatibility studies
have been satisfactorily concluded. Because of the crowding of the
existing band 435-438 MHz with unmanned amateur satellites and
manned space stations, it is desirable to study expansion of the
band.

+ The Amateur Service seeks retention of the band 1240-1300 MHz. The
Amateur-Satellite Service seeks retention of the band 1260-1270 MHz
and deletion of the "Earth-to-space only" restriction.

As reported previously, on May 17 Japan's Space Agency JAXA plans to
launch its Planet-C Venus Climate Orbiter "AKATSUKI" mission to Venus.
Also aboard will be UNITEC-1, a 15 kg, 35cm cubed nano-satellite devel-
oped by twenty-two universities and colleges of UNISEC (University
Space Engineering Consortium).

UNITEC-1 be inserted into a Venus encounter trajectory and will become
the world first university satellite which goes beyond Lunar orbit. The
main mission of UNITEC-1 is to perform technological experiments of
on-board computers and test long-range, inter-planetary communication
using amateur radio frequencies:

Downlink Frequency: 5840.000MHz, band width 20MHz
Transmission Power: 4.8W/antenna, 9.6W total
Antenna: 2 Microstrip patch antennas
Modulation: AFSK/FM 1200bps during LEO flight
CW 1bps during Interplanetary flight
Callsign: JQ1ZUN

UNITEC will rely heavily on amateur radio stations around the world
to receive its microwave downlink signal. The team has created an
Amateur Radio forum which is planned to evolve into a site for the
latest information as well as provide a path to upload received data.
See: http://sites.google.com/site/unitec1ops/amservice

Software to aid in the tracking of the satellite and decoding the
received telemetry is posted at:
http://sites.google.com/site/unitec1ops/swdownload
This includes the Initial Orbit Estimation Sheet, Unitec 1 Orbit
Estimation, and Receiving Data Analyzer

A forum to upload received UNITEC-1 data is under construction at:
http://sites.google.com/site/unitec1ops/amservice/amuploader

Many additional details are available on the UNITEC-1 Operations page:
http://sites.google.com/site/unitec1ops/

The UNITEC-1 team will use a special version of Spectran, that pro-
duces a log file of all the frequency peaks found. This will allow
them to do an offline analysis. You can download this special ver-
sion of Spectran from I2PHD, Alberto's site:

BID: $ANS-136.06

AMSAT-India attended the first Indian Small Satellite Systems Con-
ference at ISRO Bangalore. VU2POP reported that 26 univerities in
India have established amateur radio clubs and are in various stages
of Amateur Radio Satellite development.

VU2POP wrote, "As of now most of the university satellites are either
digital with only beacon downlink and no voice transponder. AMSAT
India has two linear tranponders ready. We are asking ISRO for a higher
orbit to cover a larger foot print and longer pass duration for future
AMSAT-India satellites".

As a reminder, on VO-52's 5th Birthday the HAMSAT team and ISTRAC has
requested user feedback from the Amateur Radio community. Send your
feedback to Mani, VU2WMY at wmy@isac.gov.in or vu2wmy_mani@yahoo.com.

BID: $ANS-136.07

News has been received from Vu Trong Thu, XV9AA, in Hanoi of a
Vietnamese 2U CubeSat under development. Thu wrote, "We hope to
complete the F-1 satellite by the end of 2010 and launch it to
Sun-synchronous, 98 deg inclination LEO. At the moment we are
negotiating with several launch providers to find a way into
orbit but the high launch cost is really an issue. If we can
solve the budget issue, we'll be ready to launch our cubesat
in 2011."

The satellite carries several low-resolution cameras to take photos
of the Earth along with temperature and magnetic sensors to study
space environment. Some of the project goals for the F-1 satellite
include:
+ Students to learn about aerospace engineering.
+ Demonstrate the application of COTS products to reduce cost and
time developing a small satellite.
+ Survive in space environment for at least a year.

The satellite will use amateur VHF and UHF frequencies. The IARU has
coordinated at downlink frequency of 437.485 MHz to support a 1200 baud
AX.25 telemetry link. The F-1 satellite will also transmit a beacon us-
ing a modulated Morse code audio signal on FM carrier when it is not in
range of the earth station in Hanoi. In case of emergency, DTMF tones
can be used to control the satellite to some extent. The satellite also
carries a COTS transceiver (using UHF frequency) from Microhard Systems
to experiment with higher data transmission speed.

A breadboard model of the satellite has been built and the communication
link has been tested at a range of 50km. The team is now working on the
Engineering Model of the satellite and more tests are planned including
shock, vibration and thermal tests.
