SB SAT @ AMSAT $ANS-030.01 ARISSat-1 Arrives at the International Space Station
AMSAT News Service Bulletin 030.01 From AMSAT HQ SILVER SPRING, MD. January 30, 2011 To All RADIO AMATEURS BID: $ANS-030.01
On January 28 at 0132 UTC,a Soyuz rocket lifted off from Kazakhstan carrying the Russian Progress M-09M cargo vehicle to orbit headed for the International Space Station (ISS).
While the primary cargo of the Progress vehicle is fuel, oxygen, food and other supplies, the Progress also contains AMSAT's ARISSat-1 Amateur Radio satellite.
Progress docked with the space station just two days after launch, on January 30 at 0239 UTC.
Currently ARISSat-1 is planned to be manually deployed from the ISS by Russian cosmonauts Dmitry Kondratyev and Oleg Skripochka during a spacewalk on February 16. ARISSat-1/RadioSkaf V will have simultaneous 2m FM, CW, BPSK and transponder transmissions. These multiple transmissions are created by a new software defined transponder (SDX) board. Features provided by the SDX include:
* The FM transmissions with cycle between a voice ID, select telemetry values, 24 international greeting messages in 15 languages and live SSTV images. * The CW transmissions will be callsign ID, select telemetry, and callsigns of people actively involved with the ARISS program. * The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions. The BPSK data will alternate betwen telemetry and Kursk experiment data. Free ground station soundcard demodulator and display software will be available before deployment for multiple platforms. * There also is a 16kHz wide amateur radio U/V transponder between the BPSK and FM signals. * The Kursk experiment will be sampling the amount of vacuum each day for 90 minutes and sending down data to map the vacuum change as the satellite slowly spirals into the atmosphere.

SB SAT @ AMSAT $ANS-030.02 AMSAT-UK FUNcube System Accepted for UK Space Agency UKube1 Payload
AMSAT News Service Bulletin 030.02 From AMSAT HQ SILVER SPRING, MD. January 30, 2011 To All RADIO AMATEURS BID: $ANS-030.02
Graham, G3VZV announced on behalf of AMSAT-UK this week that the FUNcube system has now been formally accepted as a participant in the UK Space Agency Announcement of Opportunity for payload pro- viders for its pilot CubeSat mission, UKube1.
Seven finalist payloads are currently under consideration with the final three or four flight payloads to be announced in March, 2011. This includes the AMSAT-UK FunCube telemetry system for science education, which will be integrated with the spacecraft as part of the program.
Graham explained, "While the UK Space Agency release does not mention the FUNcube linear U/V transponder function during evenings and week- ends, this functionality will be included in the same way that it is planned for the actual FUNcube-1 cubesat itself. The FUNcube develop- ment team is looking forward to the extra challenge of producing two sets of everything in the very short time scales required by both pro- jects!"

SB SAT @ AMSAT $ANS-030.03 1000 Days in Orbit for Ham Radio Satellite Delfi-C3
AMSAT News Service Bulletin 030.03 From AMSAT HQ SILVER SPRING, MD. January 30, 2011 To All RADIO AMATEURS BID: $ANS-030.03
Sunday, January 23 saw the 1000th day in orbit for the Amateur Radio satellite Delfi-C3, which was the first 3U CubeSat to carry a linear transponder.
Wouter, PA3WEG wrote, "The downlink is still OK and telemetry shows no big degradations. This means Delfi-C3 is still in good health. Apart from the problems with the transponder and some occasional resets and lockups, scientific data is still being received. Also, this data is still forwarded by radio amateurs to our server. Once again our big thanks for receiving Delfi-C3 and your continued support of the project."
Visit the Delfi-C3 web page at: http://www.delfic3.nl/ The radio amateur section at: http://tinyurl.com/6f362zu has the information you need to receive the satellite. There is also a link to the Rascal Software if you would like to have your amateur radio station become a part of the global Delfi-C3 monitoring network.

SB SAT @ AMSAT $ANS-030.04 ND9M/VQ9JC Maritime Mobile Satellite Operations Planned
AMSAT News Service Bulletin 030.04 From AMSAT HQ SILVER SPRING, MD. January 30, 2011 To All RADIO AMATEURS BID: $ANS-030.04
Jim, ND9M/VQ9JC plans to operate the amateur radio satellites from his merchant marine ship presently enroute from Diego Garcia (grid MI62) to Charleston, SC (FM03) via the Pacific Ocean. Jim says he has an FT897D and an FT817ND with an Arrow-2 antenna. He plans to be active from quite a few wet grids along the way. His ocean route will take him through grid fields include MI, NI, OI, OJ, PJ, PK, QK (24 hours at Guam), QL, RL, RM, AM, BM, CM. and DM.
Jim's job is seven days a week for four months straight and he will not generally be available during the normal daytime working hours so operating opportunities during these times cannot be predicted.
The majority of passes he can be on will be in the late afternoon and early evening, so AO51, FO29, and AO7 Mode B will be the focus. Early morning AO7 passes will occasionally be available. Operating during late evening passes will be likely once the ship crosses the International Date line and enters the eastern Pacific. Jim's port- able satellite station will be setup on the ship's helicopter deck.
The ship will be off the coast of southern California by the end of February and should be there for about 10 days before resuming the voyage towards Charleston via the Panama Canal, then northward around Cuba towards Jacksonville (EM90) for another stop at the end of March. The voyage will finish in April in Charleston, SC.
Jim says he has applied for an IARP permit for Panama so that, barring unforeseen regulations, he will be able to operate whatever passes occur as the ship transits the Canal.
E-mail contact for Jim is via james.t.clary.civ(at)msc.navy.mil. He plans to post regular updates on his trip's progress to the AMSAT-BB.

SB SAT @ AMSAT $ANS-030.05 Catch a Visual Glimpse of NanoSail-D in Orbit
AMSAT News Service Bulletin 030.05 From AMSAT HQ SILVER SPRING, MD. January 30, 2011 To All RADIO AMATEURS BID: $ANS-030.05
In a posting on http://www.nanosail.org/ Spaceweather.com and NASA announce they are joining forces to encourage photography of Nano- Sail-D, the first solar sail to circle Earth in low orbit.
Amateur and professional astronomers and even casual sky watchers can participate. The solar sail will occasionally be visible to the naked eye when sunlight glints off the spacecraft's 10 m2 sail, pro- ducing a spectacular flash akin to an Iridium Flare. UniverseToday predicts NanoSail-D could be five to 10 times as bright as the planet Venus, especially later in the mission when the sail descends to lower orbits.
Even novice photographers can capture such a bright event. Advanced astrophotographers, meanwhile, will want to try to image the sail through backyard telescopes. It will be a challenge (the sail is only 1 arc second across), but even fuzzy pictures could help NASA monitor the condition of the spacecraft. Cash prizes will be awarded to the first ($500), second ($200), and third ($100) place photos, judged by a NASA-appointed panel on the basis of beauty and technical merit.
The contest begins now and ends when NanoSail-D reenters the atmo- sphere in April or May 2011.

SB SAT @ AMSAT $ANS-030.06 Echoes of Apollo Call for Student Investigators & Adult Engineering Mentors
AMSAT News Service Bulletin 030.06 From AMSAT HQ SILVER SPRING, MD. January 30, 2011 To All RADIO AMATEURS BID: $ANS-030.06
Pat Barthelow, AA6EG of the Echoes of Apollo Project (the folks who brought us the 70cm Arecibo EME activity) is working with kids on the Google Science Fair. The students and adult mentors have devised a simple experiment to measure the distance to the moon using Moon Bounce.
Pat has several EME stations committed and is looking for more tech- nical support. He is also looking for additional young Co-Primary Investigators (Age 13-18) to participate.
Time is of the essence. Reply directly to: [email protected]
Pat says the students will develop the experiment, lead, analyze. Adults are needed to nurture, guide, mentor with these goals in mind:
+ Key a CW transmission or alternatively, send an audio impulse via microphone to EME TX.
+ Starting the time clock on the impulse transmission whether Audio "Clack" or CW key.
+ Recording for Science Fair presentation, using Multimedia video/audio eqiupment in the Moon bounce Station.
+ Stopping the clock when the audio/RF does RT to moon (~2.5 Seconds) and returns, and is demodulated by Moon bounce RX and presented at Audio speaker terminals.
+ Pre-measure station delays in TX and RX to develop a constant for internal equipment delays.
+ Measuring the EME interval as closely as possible, with simple equipment, say, to milliseconds. Probably take the Multimedia video/ audio to a Video editor, to measure delay, digitally.
+ Compare distance to the moon in the NASA, or US Naval Observatory databases for their actual distance to moon, at the moment of the experiment.
+ Student analyzes for errors, error sources, discusses return signal distortion, due to doppler, Libration, pulse stretching, due to spherical moon, etc.
+ Student suggests follow up experiment, to minimize measurement errors, or assuming more sophisticated equipment became available.
QUESTION: For an analog RX to audio output, what would be the best way be to measure the internal propagation delay in an [Analog, Digi- tal] receiver, from the time of arrival of the RF at the Antenna con- nector to demodulated output [Analog, Digital] at the speaker, or computer screen.
For analog receivers, is the internal RX propagation delay, in order of: microseconds? Milliseconds? For Digital receivers?
Best Regards, Pat Barthelow, Echoes of Apollo [email protected]
