Tle of CUTE-1.7+APDII on Celestrak
by ji1izr/Masahiro SANADA 25 May '08

25 May '08

Hello, everyone, de JI1IZR/Masahiro. I tryed to listen to CUTE-1.7+APDII yesterday but not caught the sound. I checked the reason and found that the TLE of this sat in "CubeSats" on Celestrak is different from "Last 30 Days' Launches" on it. The former is object L and the latter is object C. I think the latter is correct because I caught the CUTE's packet data according to it today. *************************** Masahiro Sanada de ji1izr Hiratsuka-city Kanagawa,Japan ji1izr_1975(a)nifty.com ji1izr(a)jarl.com ji1izr(a)jamsat.or.jp web: http://ji1izr.atnifty.com/ blog: http://ji1izr.air-nifty.com/ ***************************

[ANS thanks AMSAT HQ for the above information] /EX SB SAT @ AMSAT $ANS-145.02 Delfi-C3 DO-64 Tests Linear Transponder AMSAT News Service Bulletin 145.02 >From AMSAT HQ SILVER SPRING, MD. May 25, 2008 To All RADIO AMATEURS BID: $ANS-145.02 During the past week the Delfi-C3 satellite DO-64 has continued its science mission. But, during a pass over the Delfi-C3 ground station on May 15 the amateur band linear transponder was success- fully tested and activated for a short time. The CW beacon was received well and subsequently good signals using SSB were received. An audio file of the test can be found at: http://www.delfic3.nl/photoblog/wp-content/uploads/2008/05/pe4wj_transponder _test.mp3 The Delfi ground control team is currently performing tests while the spacecraft is over the Netherlands to address the downlink drop- out issue. These tests may require several passes over the ground controllers so the satellite may still experience downlink dropouts over the coming days. The current operating mode of Delfi can be found on its webpage at: http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=12 2 While in science mode Defli has continued operation on a downlink of 145.930 MHz, transmitting 1200 Baud BPSK AX.25 telemetry data. Reminder: Delfi-C3 does not have a battery on-board and will therefore only be active in sunlight. The latest keplerian elements for Delfi can also be found on the operations web page. The Delfi team reported, "Up to now, we have received over 130000 AX.25 frames from all over the world, thank you very much for your efforts and observations so far!"

May 25, 2008 To All RADIO AMATEURS BID: $ANS-145.03 Hiroki Ashida, JQ1YCZ reported this week that the Tokyo Institute of Technology enabled continuous packet telemetry on their cubesat, Cute1.7 + APD II. This was to support a 12 hour experiment of the Avalanche Photo Diode APD) as a radiation monitor of low-energy (E > 10 keV) particles trapped in low Earth orbit. Prior to the activation of this experiment packet telemetry had only been activated when the Cute1.7 + APD II cubesat was within range of the Japanese ground control station. The FM packets were received on 437.475MHz from amateur radio station around the world. Packet formats and additional satellite information can be found at: http://lss.mes.titech.ac.jp/ssp/cute1.7/fm_mode_apd_e.html [ANS thanks Hiroki Ashida, JQ1YCZ for the above information] /EX SB SAT @ AMSAT $ANS-145.04 AO-16 Operation Update AMSAT News Service Bulletin 145.04 >From AMSAT HQ SILVER SPRING, MD. May 25, 2008 To All RADIO AMATEURS BID: $ANS-145.04 Mark Hammond, N8MH, AO-16 Command Station gave an update of testing on the AO-16 satellite. Mark commented, "Indeed, over the last several days you are likely to have found AO-16 silent. There appears to be something in the spacecraft shutting down the transmitter after a short, random period of time. Current speculation on the problem in- cludes a temperature issue that has reared its ugly head now that the eclipse periods are increasing and the spacecraft internal temperatures are decreasing. It may be a hardware timer. It does not appear to be a battery issue." The ground control station will manually turn the satellite ON and then configure it for voice operations. This is a manual process and command stations are limited to the East coast of the US. As schedules permit, we'll try to turn it ON; for now, it's the best we can do. Time will tell if the current situation will stay the same, improve, or get worse.

May 25, 2008 To All RADIO AMATEURS BID: $ANS-145.05 A report has been received via Michael Chen, BD5RV/4 that a new amateur radio satellite to be launched by China, CAS-1 has completed its IARU frequency coordination and the hardware has been finished. The payload is planned to include a CW Telemetry Beacon, Linear Trans- ponder, FM repeater and a Digital Store-forward Transponder. The oper- ations will use 70cms downlinks and 2 meter uplinks at 500mW output power. The satellite is expected to have a mass of 30kgs and be launched from China into a sun syncronous orbit with a 670km apogee. The CAS-1 team is waiting for another payload to be finished before launch which at this point is predicted to happen in early 2009.

May 25, 2008 To All RADIO AMATEURS BID: $ANS-145.08 The Russian Federal Space Agency announced the successful launch of the Yubileiny, a 45 kg small satellite, on May 23 from the Plesetsk Launching Site into low earth orbit. The motive for development of Yubileiny small spacecraft was the 50th anniversary of the first space satellite. One mission goal includes flight qaulification of the new space systems and equipment. Radio amateur operators all over the world will be able to receive the tele- metry downlink utilizing RS-style CW telemetry 435.315 MHz using the callsign RS30. The satellite transmits a cyclic series of messages lasting for 4 minutes including a call signal and TM-data (10 seconds); a voice message (1 minute); a pause (50 seconds); the first artificial satellite imitated signals (10 seconds); an image (1 minute); with a final pause (50 seconds). Aerospace Vehicle Laboratory SCC is the primary the satellite con- trol. A similar Satellite Control Center has been established at the Siberian State Aerospace University in Krasnoyarsk to allow students and research engineers can receive and analyze the telemetry in coop- eration with the specialists at JSC Academician M.F. Reshetnev Infor- mation Satellite Systems center.

Dutch School Contact Delta Researchers Schools 2008, Space Expo in Noordwijk, the Nether- lands, had an ARISS contact via telebridge station WH6PN in Hawaii on Friday, May 23. Twelve Dutch primary schools which participate in the Delta-project were represented at Space Expo. The project is a cooper- ation of the Dutch ministry of Education, Culture and Science, the European Space Agency (ESA) and NASA. The schools participating in the project use the themes of space and space exploration to teach science and technology. Three children (ages 7 - 12) from each school were pre- sent. The audio for this event was fed into the EchoLink AMSAT (101 377) and JK1ZRW (277 208) servers. 2. Cindy McArthur Receives Silver Snoopy Award Last week, Teaching From Space Project Lead Cindy McArthur became the recipient of a Silver Snoopy award. Astronaut Barbara Morgan, KD5VNP, presented the award in appreciation for McArthur's work and support of educational activities throughout the STS-118 mission which included an Educational Downlinks videoconference and an ARISS contact.

YUBILEINY
by john heath 24 May '08

24 May '08

Good signals from Yubileiny on the low elevation pass in range UK (IO92IO) 22:00 utc Saturday. Beacon switched to continuous tone only, as the satellite neared its most northerly point. I guess it was in darkness but didn't manage to check as I was watching the signal display in hamscope, my preferred soundcard software for reading Morse. The tone went off for a few seconds then resumed. Be interesting when we get the telemetry equations. I see from the web page that "Yubileiny is the first satellite developed on basis of non hermetic platform" 73 John g7hia

Phase 3-E Launch date?
by Keith Baker KB1SF/VA3KSF 24 May '08

24 May '08

Greetings All! Does anyone have any word regarding the final integration and actual launch dates for Phase 3-E? Was anything about Phase 3-D discussed at Dayton? Everything I'm reading on the AMSAT-DL Web site is devoid of any firm launch dates and the AMSAT-NA Web site simply says "January 2009". How firm is that date? Has a launch contract been let? 73, Keith KB1SF / VA3KSF Past President AMSAT-NA
