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:

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 at isac.gov.in or vu2wmy_mani at yahoo.com.

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.

In addition to regular membership, AMSAT offers membership in the
President's Club. Members of the President's Club, as sustaining donors
to AMSAT Project Funds, will be eligible to receive additional benefits.
Application forms are available from the AMSAT Office. And, with that
please keep in mind the radio amateur who was LED to believe it was a 
good time for this humor: His friends were shocked and their stomach
did flip-flops but he soon rectified the situation and that phase soon
passed. We were no longer choked up and encountered no more impedance
to our progress.
