The 2010 Space Colloquium - the 25th held by AMSAT-UK, is taking 
place on July 31 and August 1 at the Holiday Inn in Guildford, 
England.

As usual there will be many interesting presentations and demonstra-
tions from the developers and users of the ever increasing number of 
amateur radio satellites. In addition there will be talks on nano 
propulsion systems, solar sails, cubesat sized linear transponders, 
the GENSO ground station network, GNU radios and numerous other 
topics.

It is still possible to attend the meeting itself, although the "early
booking" rates may now no longer be available  - for booking details

South Pacific Total Solar Eclipse Captured in AO-51 Telemetry Data

On July 11 a total solar eclipse was observed in the southern Pacific 
Ocean. The path of totality stretched across the South Pacific Ocean, 
but the Moon's umbral shadow didn't make landfall except for a few 
spots such as the Cook Islands and Easter Island, and southern Chile 
and Argentina. A partial eclipse was visible from a much larger region 
covering the South Pacific and southern South America. 

Masa, JN1GKZ noted a glitch in AO-51's Whole Orbit Data file (WOD) 
in the Total Array I current while AO-51 was located east of Argentina 
at the time. AO-51 Control Station, Mark, N8MH replied, "You have made 
a great observation, and I think you are exactly right about the cause 
of the observed 'glitches' in the telemetry.  Usually at this point in 
its orbit we would observe AO-51 charging its batteries at a steady 
rate from fully illuminated panels."

Mark plotted some of the telemetry collected from 1800-2130utc) and 
posted it at:

Alex, OZ9AEC ran a simulation using the Celestia space simulator and 
observed a partial solar eclipse as seen from AO-51. He recorded this
simulation to a video and you can watch at:

A new distance record of 7843 km (4898 Miles) via AO-7 was established 
on July 15 between Luciano, PY5LF and Joe, K3SZH. The estimated maxi-
mum range of AO-7 is ~7,900 km. Pirajá, PS8RF noted that the log of 
QSO can be seen on the unofficial AO-7 web site:

For several days last week, Colonel Doug Wheelock, KF5BOC, took to 
the air from the ISS to talk to hams around the globe. The 2-meter
FM phone frequencies for voice operation with the ISS over the US 
are 144.490 MHz uplink with 145.800 MHz downlink.

Dee, NB2F noted, "I Just talked with the ISS. Loud and Clear. Good 
sigs and thanks to the ISS crew for making contacts." Damon, WA4HFN 
wrote, "I made my first ISS voice contact with NA1SS. He was full 
meter reading!" Greg, KO6TH also noted the strong downlink signal.

Later in the week the ISS crew activated the SSTV equipment to support
the Moscow Aviation Institute experiment (MAI-75) on July 15 and 16. 
The system operated the space cam in slide show mode. The latest ISS 
SSTV information can be found on-line at:

ARRL Education and Technology Program Coordinator, Mark Spencer, 
WA8SME conducted the Dayton Amateur Radio Association sponsored 
ARRL TI-2 Teacher's Institute - Space this week in Dayton. The 
purpose of this teacher's institute is to instruct teachers on 
how to access satellites for use in their classrooms.  The four 
day institute will involve a lot of on-the-air activity on the 
birds.  

Concluding a successful session, Mark wrote, "I want to offer my 
sincerest thanks to the satellite community, Drew, and AMSAT for 
the support that you gave us during the TI-2 Space this year. Over 
the last three days, your support in making contacts with the tea-
chers, and in particular, the dedicated SSTV activity on AO51, has 
made the TI-2 Space a huge success this year. I wish each of you 
could have seen the glowing light bulbs in the teachers' heads at 
each successful satellite contact. I am confident that they will 
be taking what they learned this week back into their classrooms 
to make space 'alive' for their students.  Thanks for the patience 
you showed as these novice satellite operators learned the tricks
of the trade."

Mark also noted the success of having 8 satellite ground stations, 
and antennas operating at one time.

Reporting from the Upagrah Amateur Radio Club VU2URC, at the ISRO 
Satellite Centre in India, Mani, VU2WMY said the July 12 launch of
the 17th flight launch of Indian space agency's Polar Satellite 
Launch Vehicle PSLV-C 15 from Sriharikota was successful. Mani wrote,
"All the five satellites including the StudSat and TISat aboard the  
PSLV-C15 were successfully separated from the vehicle and they are  
in the [correct] 640 Km orbit right now."

The PSLV-C15 launch included a primary payload of the CartoSat-2B
remote sensing satellite and AlSat-2A satellite. The three other
satellites included AISSat-1, a Norwegian Defence Research Establish-
ment satellit to demonstrate a new maritime AIS receiver; and the 
TISat-1 and StudSat amateur radio banded cubesat payloads.

TIsat-1:  Swiss CubeSat
Uplink:   145.980MHz FM, AFSK
Downlink: 437.305MHz FM, AFSK
Beacon:   437.305MHz CW
Callsign: HB9DE
http://www.spacelab.dti.supsi.ch/tiSat1.html

StudSat : India CubeSat
Uplink:   437.505MHz, 9600bps FSK
Downlink: 437.505MHz, 9600bps FSK
Beacon  : 437.861 MHz (10 mW),   20bps ASK
http://www.teamstudsat.com/

Shortly after launch Alan, ZL2BX reported, "Good signals from TISat 
over ZL 0926 to 0936 when the signals stopped abruptly shortly before 
predicted LOS. Copied HI HI HI TISAT H."

Christian, F1AFZ, noted the beacon on 437.305 MHz TIsat-1 was on over 
Europe HI HI HI TISAT K." He posted a recording of the pass at:
listen: http://www.f1afz.fr/satellites/new_2010/tisat_12-07-2010_8h45tu.mp3

Paolo, HB9TYP says TIsat-1 is in power/battery saving mode during 
eclipse. Its transmission is limited or completely shut off according 
to on board rules. On behalf of the TIsat-1 team Paolo thanks the AMSAT 
community for signal reports already received. He says you can find the
latest keps and other details on the project and mission status webpages:
http://www.spacelab.dti.supsi.ch/tiSat1MS.php. The TIsat-1 team invites
your continued feedback. While copying the beacon please collect and 
report the character emitted AFTER "HI HI HI TISAT" along with time in 
UTC, your location and signal quality.

+ AMSAT Keplerian Elements Guru Ray Hoad, WA5QGD noted this week
  that the following satellites have decayed from orbit and have 
  been removed from the KEPS distribution list:
  1. DRAGNSAT Cat# 35690, Decay date 3-17-2010.
  2. POLLUX Cat# 35693, Decay date 3-29-2010.
  STUDSAT Cat# 36801, Launched 7-12-2010 has been added to the 
  distribution list. The Swiss Cubesat TIsat-1 has now been iden-
  tified as object #36796 and will be added shortly.

+ Stu WA2BSS reminds radio amateurs that the next Hudson Valley
  Satcom Net will meet on Thursday July 22 at 2000 EDT (2400 UTC).
  The Echolink node is: N2EYH-L, The net meets on the air on the
  146.97 MHz repeater.  More info: http://www.hvsatcom.org.

+ Mineo Wakita, JE9PEL noted that Japan's CO-65 (Cute-1.7+APD II) 
  is in Digipeater Mode during weekends. The CO-65 digipeater is 
  accessed using standard AX.25 protocol. The uplink of the digi-
  peater is 1267.600 MHz and the downlink 437.475 MHz using 9600 
  bps GMSK. Mineo refers interested amateurs to these web pages

+ WorkedGrids is a freeware Windows application that displays a map 
  showing Amateur Radio grid squares contacted and logged using a 
  third-party logging program. The app was developed by VE2ZAZ, and 
  uses colors to display information on a per-band basis. Up to four 
  bands can be displayed concurrently. For its input, the program 
  reads the plain-text ASCII log files generated by most logging pro-
  grams. The file is read at a set interval and the worked grid squares 
  on the map are updated in a dynamic way as the contest progresses 
  and the log file is periodically saved. WorkedGrids can be down-
  loaded from http://tinyurl.com/24okrtm.

+ SaturnDaily.com noted an interesting NASA JPL video produced from
  Cassini orbiter radar data showing a fly-by simulation of Ontario 
  Lacus, the largest lake in the southern hemisphere of Saturn's moon 
  Titan. Watch at: http://www.jpl.nasa.gov/video/index.cfm?id=912

Application forms are available from the AMSAT Office. And with that
please keep in mind the young ham who got a job in the shoe factory but
found that he didn't fit in. When he tried working at the deli they told
him he didn't cut the mustard. He found that he just wasn't up to it in
his latest job feeding the giraffes at the zoo.
