AMSAT-UK Announces Colloquium 2012 & Issues First Call for Speakers

The AMSAT-UK International Space Colloquium will be held on 
September 14-16, 2012.

The colloquium attracts an international audience from across Eur-
ope as well as North America and the Middle East. Attendees range 
from the builders of the CubeSats and Nanosats, those who communi-
cate through them and beginners who wish to find out more about 
this fascinating branch of the hobby.

It provides a rare opportunity to chat with satellite designers and 
builders, discussions frequently continue until the early hours of 
the morning.

A Gala dinner is held on the Saturday evening along with the fund 
raising auction.

AMSAT-UK invite speakers, about amateur radio space and associated 
activities, for this event. They are also invited to submit papers 
for the “Proceedings” document which will be published at the same 
time but printed papers are not mandatory. We normally prefer au-
thors to present talks themselves rather than having someone else 
give them in the authors’ absence. We also welcome “unpresented” 
papers for the Proceedings document.

FIRST CALL FOR SPEAKERS
----------------------- 
This is the first call for speakers for the AMSAT-UK International 
Space Colloquium 2012 which, due to the Olympic & Paralympic Games, 
will be held this year on the weekend of September 15-16, 2012 at 
the Holiday Inn, Guildford, GU2 7XZ, United Kingdom.

This Colloquium will take place a few weeks before the planned 
launch of AMSAT-UK’s FUNcube-1 satellite carrying a 435/145 MHz 
linear transponder for SSB/CW communications.

AMSAT-UK invites speakers, to cover topics about micro-satellites, 
CubeSats, Nanosats, space and associated activities, for this event.

They are also invited to submit papers for subsequent publishing on
the AMSAT-UK web site. We normally prefer authors to present talks 
themselves rather than having someone else give them in the authors’ 
absence. We also welcome “unpresented” papers for the web site.

We appreciate that it is not always possible to give a firm indica-
tion of attendance at this stage but expressions of interest would 
be appreciated.

Submissions should be sent *ONLY* to G4DPZ, via the following routes:

e-mail: david dot johnson at blackpepper dot co dot uk

Postal address at http://www.qrz.com/db/G4DPZ

AMSAT-UK also invite anyone with requests for Program Topics to sub-
mit them as soon as possible to G4DPZ. Invitations for any papers on 
specific subjects will be included in the future call. Likewise if 
anyone knows of a good speaker, please send contact and other infor-
mation to G4DPZ.

India VO-52 Satellite Recovery in Progress

Mani, VU2WMY, Secretary & Station-In-Charge at the Upagrah Amateur 
Radio Club VU2URC in India reported that on March 6 the ISRO Satel-
lite Centre recovered operation and control of HAMSAT VO-52. This
satellite had been heard during expected passes since February 28.

Mani wrote, "I can share at this moment is 'HAMSAT VO-52' is in 
'Excellent Health' after recovery operations. Right now, it is under 
observation. The decision in regards to switching 'ON' the transpond-
er is pending clearance from ISRO. This decision expected soon. The 
user community will be informed well in advance about the transponder 
switching."

ISRO Announces Plan to Turn on Dutch Transponder
------------------------------------------------
On March 8, Mani, VU2WMY, reported that news had been received from
Mr. T. Parimalarangan, HAMSAT VO-52 Operations Director at ISTRAC/ISRO
that, "After 'In-Orbit Maintenance Operations' the decision to turn 
'ON' Transponder No 2 i.e. The Dutch Transponder made by William 
Leijenaar PE1RAH on March 8 during orbit # 37006 over India."

Dutch Transponder Activation on Hold for One Week
--------------------------------------------------
Unfortunately, we are sorry to inform that the 'Expert Committee'  
overseeing the VO-52 (HAMSAT) performance has advised to extend the  
'Observation Period' by an other week.

Hence, the decision to switch on the transponder # 2 is now put 'ON  
HOLD' till further notice. Inconvenience caused to the users is  
regretted.

This latest decision is just only a postponement and nothing to worry  
about the health of the spacecraft. We re-assure you all that VO-52 is  
very strong and in a 'Perfect Health' condition.

Once the Dutch transponder is switched on it will use the following
frequencies:

Uplink frequency:   435.250 MHz
Downlink frequency: 145.900 MHz
Beacon:             CW at 145.859330 MHz (145.86 MHz)
Output level of Beacon Carrier: 18 dBm

ISRO invites a 'Critical Comparative Signal Report' between the 
Indian and Dutch transponder would be of great help for further 
evaluations and necessary actions for the maintenance the trans-
ponder in good and healthy condition for better services and also, 
the inputs would be very valuable to the respective transponder 
designers. Please send your feedback to tprangan at istrac.org.

Summaries from stations monitoring for VO-52 can be entered and viewed 
on the Live OSCAR Satellite Status Page: http://oscar.dcarr.org/

March 17 for AMSAT-LU Balloon Test Flight of LUSEX Satellite Systems

AMSAT-Argentina announced they are planning to test systems of the 
LU Satellite EXperiment (LUSEX) satellite during a high altitude 
balloon flight up to 100,000 feet. This is scheduled for March 17 
at 1500 UTC. Direct reception of the balloon flight is estimated to
extend to 400 miles from the City of Junin, west of Buenos Aires,
Argentina. (See http://www.amsat.org.ar/junincubr.jpg for estimated
coverage map.)

The payload will feature several radio and telemetry experiments:

+ Crossband FM Repeater 
  Uplink   435.950 MHz FM (123 Hz tone)
  Downlink 145.950 MHz FM

+ SSTV Downlink 145.950 MHz FM
  ROBOT-36 in real time, showing the view from the balloon every 
  5 minutes during ascent/descent, longer interval at high alti-
  tude. Video will also be recorded and recovered at the end of
  the flight.

+ APRS Data
  APRS 1200 baud packet on 144.930 MHz, and 145.950 MHz.

+ Telemetry Downlink 145.950 MHz
  If the crossband repeater is in use a warning bip at 40 seconds 
  will indicate telemetry is coming, which is sent if the repeater 
  is not in use. If the repeater continues to be busy then 2 bips
  will indicate APRS packets will be sent.

  CW telemetry (modulated FM on 145.950 MHz) will be sent every
  5 minutes with the following sequence: CQ LU7AA, sequence number, 
  external and internal temperatures °C and battery voltage. 

+ User Telecommand Experiment
  The 435.950 up / 145.950 down crossband repeater will accept user
  DTMF command to return a signal report. Sending B* on the uplink
  will return S5 (average signal strength) or P10 (S9+10 signal
  strength) modulated CW tones on the 145.950 MHz FM downlink.

APRS trajectory will update every minute, including speed, height, 
external and internal temperatures and 7.2v battery voltage. This
can be monitored directly on 144.930 MHz for stations in range. It
will also display at: http://aprs.fi/?call=lu7aa-11 . The APRS 
symbol will display as a balloon during ascent, and as a glider 
during parachute descent. The AMSAT-LU APRS Igate LU7AA-10 on 144.930 
and 430.930 MHz will be active. Maps for UI-View APRS tracking can
downloaded from http://www.amsat.org.ar.

Stations making a contact via the balloon payload may qualify for a
certificate. See http://www.amsat.org.ar/certsat.html for details.

AMSAT-LU thanks the members of Radio Clubs of Junin, QRM Belgrano, 
APRS Group, Don Bosco Ramos Mejia School, gliders Clubs of Zarate, 
Junin and Cañuelas, and the twelve Amsat-LU members development team.
Reports from radio amateurs during previous flights are appreciated
and they look forward to your reports during the March 17 flight.

KB8VCO and W8ZCF ARISSat-1 SSTV Contact Featured in the Press

The Cincinnati (Ohio) Press web featured a story about the successful
SSTV contact via ARISSat-1 between Farrell Winder, W8ZCF and his son, 
Jeff Winder, KB8VCO.

The Winders teamed together and after many, many tries were success-
ful in sending and receiving a picture of Farrell Winder's automobile 
license plate.

The Winders used two computers, two radios, and two rotatable outside 
antennas on towers to aim and to pinpoint the satellite antenna. Con-
ditions were challenging as the satellite was traveling at 18,000 MPH 
at an altitude of 225 miles, which provided a window of opportunity of 
only up to about nine minutes while its footprint was passing within 
range of Cincinnati.

The successful end result was a lot of hard-earned fun and excitement 
to work with very small signals from “outer space” and overcome the 
setback caused by the missing antenna on ARISSat-1.

The picture the Winders sent and received is apparently one of the 
only complete pictures sent and received. Two other operators tried 
a similar undertaking, but received just portions of pictures.

Since ARISSat-1 had no propulsion system to sustain altitude it enter-
ed the Earth's atmosphere on Jan. 4, 2012 and disintegrated.

The story can be read on-line at:
