[amsat-bb] new ISS small satellite deployment system by JAXA
JAXA announced new ISS small satellite deployment system. The deployment use Kibo's airlock and robot arm. Kibo is the Japanese Experiment Module (JEM). The satelltes deliver to ISS in cushoning bag by supply ship Progress or HTV. The satellites are equiped on the deployment feature. The deployment feature is put overboard through the airlock. The robot arm grabs the deployment feature, set the position and deploy the satellites. The deployed satellites reenter about 100 days. Now, JAXA put out a call for Japanse satellites to demonstrate this new system. The satellite is 1U, 2U or 3U CubeSat. Total size is 4U. Tow to four satellites will be selected (eg 1U+3U, 1Ux2+2U, 1Ux4). Here is the demonstration plan May 2011: satellites selection May 2012: deliver satellites to JAXA Sep 2012 or later: deployment using the new system The new system will relax vibration test condition compared to rocket launch. This will be good news for satellite manufactures. The new deployment system will make much satellite launch chances. The press release material is on the JAXA's web site.

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. From what I've read from page 43 here: http://eclipse.gsfc.nasa.gov/SEpubs/2010/TP214171a.pdf the eclipse was from 18:15 to 20:52 UTC.Look also at the areas experiencing eclipse. Please be aware that the clock on AO-51 runs fast. It is now about 3 minutes fast, so look at telemetry timestamped from about 18:18 until 20:55 UTC. Since the duration of the solar eclipse was 2 hrs 39 min (or 159 mins) and AO-51 orbits every 100 minutes or so, it could have been affected two times. I've plotted some of the telemetry collected from that period (telemetry from 1800-2130utc) and posted it here: http://www.amsat.org/amsat/ftp/telemetry/ao51/2010WOD/July2010/Wd071100_1800to2130utc_solar_eclipse.xls And here's a screenshot of AO-51 at the time: http://www.amsat.org/amsat/ftp/telemetry/ao51/2010WOD/July2010/ao51_11July2010_2045utc_solar_eclipse.jpg 73!

[amsat-bb] XW-1 launch date?
ANS-333 shows XW-1 expected launch date is middle December. I heard XW-1 will launch with HJ-1C by CZ-C2 launcher. If this is true, NASA Space Calender http://www2.jpl.nasa.gov/calendar/calendar.html shows its launch date is March 2010. When will XW-1 launch??

[amsat-bb] AO-51 lunar landing special operation over JA
Stations located in JA and neighboring nations will be able to hear the lunar landing 40th anniversary special downlink, voice messages and robot 36 SSTV picture which are same as transmitting over North America and Europe. Please watch AO-51 435.300MHz FM downlink passes over JA. Special downlink will transmitt 20th evning and 21st mornig in JA. QSL will issue from AMSAT-NA. QSL info is shown on the web site. http://www.amsat.org/amsat-new/echo/CTNews.php JA6PL and some othre stations support this event. Thank you, Drew and the AO-51 operations group! Masa JN1GKZ If there is a station or two there with excellent L band uplink capabilities who would like to relay the audio for us, we can do it. Email the ao51-modes list and myself if you would like to volunteer. The same goes for JA or anywhere else. 73, Drew KO4MA - Original Message - From: Roland Zurmely py4...@yahoo.com To: amsat-bb@amsat.org Sent: Saturday, July 18, 2009 8:08 PM Subject: [amsat-bb] AO-51 Control Team News July 20 AMSAT-NA will mark the 40th anniversary of the first manned lunar landing with a special event on AO-51. AO-51 will transmit a message commemorating the event Monday, July 20 during evening passes in the U.S. and Europe. The message will be transmitted on the 435.300 MHz FM downlink and will contain a Robot 36 SSTV image as well as a voice message. in the U.S. and Europe Why not in south america ?

[amsat-bb] Solar Eclipse 22nd July
Solar eclipse is visible at Asia and Pacific on 22nd July. Very limited area is able to see total solar eclipse. Many amateur satellites pass above the solar eclipse area. Electric power generated by solar cells will show very interesting behavior under solar eclipse. How about collecting telemetry and ploting solar cell power condition? Temperature may also show interesting look. I checked the telemetry transmitting satellite orbit around Japan. The following satellites pass above solar eclipse area. COMPASS-1, FO-29, CO-66, CO-58, DO-64, STARS, PRISM, SOHLA-1, AO-27, NO-44 There is something to be said for DO-64 condition. Will DO-64 stop transmitting telemetry under the solar eclipse? If AO-27 store telemetry as WOD, WOD shows complete solar eclipse condition. Let's try to collect telemtry under solar eclipse! solar eclipse info http://eclipse.gsfc.nasa.gov/SEmono/TSE2009/TSE2009.html Masa JN1GKZTokyo Japan ___ Sent via amsat...@amsat.org.
