SB SAT @ AMSAT $ANS-311 03 November 15 Deadline for NASA CubeSat Initiative Proposal
AMSAT News Service Bulletin 311 03 From AMSAT HQ SILVER SPRING, MD November 7, 2010 To All RADIO AMATEURS BID: $ANS-311 03
NASA made the first open announcement to create an agency-prioritized list of available CubeSat auxiliary payloads in April 2010 Additional CubeSat launch capacity is still available in 2011 and 2012, so NASA released a second announcement of CubeSat integration and launch oppor- tunities CubeSat mission proposers must still be educational institu- tions and contribute to NASA strategic goals and outcomes
Investigations proposed for this pilot project must address an aspect of science, exploration, technology development, education or opera- tions encompassed by NASA's strategic goals and outcomes as identified in the NASA Strategic Plan and/or NASA's Education Strategic Coordina- tion Framework
Collaborators may be required to provide partial reimbursement of approximately $30,000 per CubeSat NASA will not provide funding to support CubeSat activity or development Selection does not guarantee an availability of a launch opportunity
The complete CubeSat Launch Initiative Announcement can be viewed on-line at NASA gov at http://tinyurl com/2b97n6r

SB SAT @ AMSAT $ANS-311 05 FO-29 Status Update
AMSAT News Service Bulletin 311 05 From AMSAT HQ SILVER SPRING, MD November 7, 2010 To All RADIO AMATEURS BID: $ANS-311 05
Yutaka Murata, JA1COU reported news from the Japan Amateur Radio League (JARL) FO-29 command team testing this past weekend when continuous commands were transmitted to the satellite when it was in range of Japan
The current hypothesis of the recent shutdown of the satellite is that the temperature aboard FO-29 is too high to allow continuous operations and to accept commands or any other satellite operations
Eclipse of FO-29 is: November 1 0% (full illumination) November 20 14% November 30 17%
It is expected that the temperature aboard FO-29 will drop as the length of eclipse increases FO-29 is designed to work over a wide temperature range Because of degradation over time in orbit it is possible that some components may have lower performance The JARL Command Team hopes that FO-29 will accept commands and resume operation when the temperature cools down during increased eclipse

SB SAT @ AMSAT $ANS-311 06 OSCAR-11 REPORT 31 October 2010
AMSAT News Service Bulletin 311 06 From AMSAT HQ SILVER SPRING, MD November 7, 2010 To All RADIO AMATEURS BID: $ANS-311 06
This report covers the period from 30 September to 31 October 2010 During this time the satellite has been heard from 09 to 19 October and from 30 October At the time of writing it is transmitting and is expected to continue until 09 November
Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames
The satellite is now transmitting during eclipses, although signals are weaker at those times This indicates that there is still some capacity remaining in the battery
The on-board clock is now very stable It gained only ten seconds in 33 days This is comparable with its accuracy when the satellite was fully operational, when it gained approximately one minute per year However, there is still an accumulated loss of 309 days, which has occurred during eclipses of the last few years
Operation during eclipses and stability of the on-board clock suggest that some part of the system may have recently failed 'open circuit' thus reducing the overall power drain of the system, and allowing more power to be available during eclipses There was an unexplained current drain observed when analogue telemetry was last transmitted This fault might have cleared
The Beacon frequencies are -
VHF 145 826 MHz AFSK FM ASCII Telemetry
UHF 435 025 MHz OFF
S-band 2401 5 MHz OFF
Reception reports have been received from Jeff N3QO, Rod CX2ABP and Ian KI4HLV/6Y5 (G4JMM) Many thanks for those and to everyone who posted reports on the satellite status website This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites Strongly recommended for future reports! Reports around the expected times of switch-on and switch-off are of special interest The URL is http://oscar dcarr org/index php
OSCAR-11 transmits on 145 826 MHz , set receiver to NBFM The satellite has a characteristic sound, rather like raspy slow morse code, sending "di di dah dah dah dah dah dah dah" sent over a period of five seconds If you are receiving a very weak signal, switch the receiver to CW or SSB You should hear several sidebands around the carrier frequency and should be able to hear the characteristic 'morse code like' sound on at least one sideband
Please note that you need a clean noise-free signal to decode the signals, and your receiver must be set to NBFM mode, for a decoder to work
If you need to know what OSCAR-11 sounds like, there is an audio clip on my website www g3cwv co uk/ which may be useful for identification and as a test signal for decoding
The current status of the satellite, is that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed The status channels 60 to 67 are still working The real time clock is showing a large accumulated error, but is now incrementing accurately to within a few seconds per month The day of the month has a bit stuck at 'one' so the day of the month may show an error of +40 days for some dates The time display has switched into 12 hour mode Unfortunately, there is no AM/PM indicator, since the time display format was designed for 24 hour mode
The spacecraft computer and active attitude control system have switched OFF, ie the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed
The watchdog timer operates on a 20 day cycle The ON/OFF times have tended to be very consistent The average of many observations have shown this to be 20 7 days, ie 10 3 day s ON followed by 10 4 days OFF
Listeners to OSCAR-11 may be interested in visiting my website If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear The last telemetry received from the satellite is available for download The website contains an archive of news & telemetry data which is updated from time to time It also contains details about using a sound card or hardware demodulators for data capture There is software for capturing data, and decoding ASCII telemetry The URL is www g3cwv co uk

SB SAT @ AMSAT $ANS-311 07 ARISS Status - 1 November 2010
AMSAT News Service Bulletin 311 07 From AMSAT HQ SILVER SPRING, MD November 7, 2010 To All RADIO AMATEURS BID: $ANS-311 07
On Friday, October 29, an Amateur Radio on the International Space Station (ARISS) contact was held between students from Funakata Elementary School in Nagoya, Aichi, Japan and astronaut Shannon Walker, KD5DXB on the International Space Station (ISS) The youth were able to get in 16 questions before the ISS went over the horizon Approximately seventy students, guests and media were present
Astronauts Joe Acaba, KE5DAR and Aki Hoshide, KE5DNI participated in simulated ARISS school contacts with students attending Ralph McCall School in Airdrie, Alberta, Canada on Tuesday, October 26 The training sessions were terrestrial-based amateur radio contacts using ARISS equivalent equipment
Acaba, who is slated to fly with Expedition 31, also had an ARISS refresher course on Wednesday, October 27 for his upcoming mission in 2012
