SB SAT @ AMSAT $ANS-357 02 OSCAR-11 REPORT

                OSCAR-11 REPORT

20 December 2007

RECEPTION REPORTS REQUESTED!

Please send reception reports to xxxxx@amsat org (please replace xxxxx by g3cwv) or post to amsat-bb If you are able to record the satellite as a WAV file, please do so, but let me know what you have, before sending it!

If you need to hear what the satellite sounds like, please visit my website www users zetnet co uk/clivew/ The satellite transmits on 145 826 M Hz set receiver to NBFM

During the period 15 November to 19 December 2007 the satellite has been heard from 18 to 20 November Signals were variable in strength, mostly weak

The real time clock has lost a further 4 29 days since 08 October When last heard it was 74 26876 days slow

I am indebted to Kevin WA6FWF, Peter ZL3TC, Armando N8IGJ and Thomas HB0SKA for their reports Many thanks

Eclipses have continued and are expected until mid January 2008 Although the maximum duration of the current eclipses is less than those earlier this year, it is doubtful whether the satellite will be heard for any sustained period Even in continuous sunlight during September and October the satellite was unable to support continuous operation

It is likely than the satellite will only be heard by chance, by stations listening for other satellites on 145 826 Mhz

The current status of the satel lite, 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, although over short periods timekeeping is accurate to 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 More data is required to determine exactly when the date changes

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 When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexp lained current drain on the main 14 volt bus After 23 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude

The watchdog timer now operates on a 20 day cycle The ON/OFF times have tended to be very consistent The average of many observations show this to be 20 7 days, ie 10 3 days ON followed by 10 4 days OFF However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle When this occurs, the beacon is OFF for 20 7 days

The Beacon frequencies are -

VHF 145 826 MHz AFSK FM ASCII Telemetry

UHF 435 025 MHz OFF

S-band 2401 5 MHz OFF

Listeners to OSCAR-11 may be interested in visiting my website If you need to know what OSC AR-11 should sound like, there is a short audio clip for you to hear There is an example of the latest telemetry received from the satellite The website contains an archive of news & telemetry data It also contains details about using a soundcard or hardware demodulators for data capture There is software for capturing data, and decoding ASCII telemetry The URL is www users zetnet co uk/clivew/

SB SAT @ AMSAT $ANS-357 05 President's report

AMSAT News Service Bulletin 357 05 From AMSAT HQ SILVER SPRING, MD December 23, 2007 To All RADIO AMATEURS BID: $ANS-357 05

President's Report From the 2007 AMSAT-NA Annual Meeting

2007 Symposium, Pittsburgh, Pennsylvania

Over the past year AMSAT has developed a well-defined mission and vision for an exciting future of amateur radio in space In fact, some of the items we have discussed here at the Symposium may perhaps become known as the weekend that changed amateur radio

In response to input from the members, AMSAT's Board of Directors and Officers have undertaken a clearly defined Mission and Vision of our current and on-going work:

AMSAT's Mission Statement

 + AMSAT designs, builds and operates experimental satellites and
   promotes space education as a non-profit, volunteer organization

 + AMSAT develops and fosters partnerships with government, industry,
   educational institutions and fellow amateur radio societies

 + AMSAT leads the way on technical and scientific innovation

 + AMSAT develops and fosters an environment encouraging the
   training and development of designers and operators

AMSAT's Vision Statement

 + AMSAT will deploy high earth orbit (HEO) satellites, initially
   with daily coverage, evolving to continuous coverage

 + AMSAT will participate in human space missions

 + AMSAT will support a stream of LEO satellites which are developed
   in cooperation with the educational community and other amateur
   satellite groups

The New Reality

Going forward, we are realizing a new reality of the future of Amateur Radio in space There is a distinct shift away from the aegis of government/military sponsored spaceflight to a field that will be more and more driven by commercial consideration This development signifies that space missions will become driven by a business-case model While our new missions will provide great new services to the Amateur Radio community, we cannot afford to pay millions for them

The reality is that no one will pay for more "toys" for us to play with To gain the funding necessary our missions must excite the funding sources AMSAT will be required to fit into the business-case models of just about every launch opportunity we wish to pursue in the future

Your Board of Directors and Officers have identified two key areas which capture the attention and imagination of potential funding sources:

 + Education - The Phase IV geosynchronous satellite will enable
   TDRS-like support of ARISS
 Ten minute school contacts will grow
   to hours-long contact with the Space Station
 We are working on
   an expanded curriculum with the ARISS and NASA teams
 We are
   planning the establishment of the AMSAT Institute which will
   train educators to bring space into the classroom using AMSAT's
   Phase IV facilities in conjunction with ARISS


 + Emergency Communications - The Advanced Communications Payload
   is being co-developed as spaceflight and ground station gear
   available for rapid deployment or pre-positioning into disaster
   areas to provide 365/24/7 communication capability
 This proposal
   is gaining some attention within the Homeland Security organization

AMSAT's Current Development Plans

Consistent with our Vision Statement we are continuing development of Phase III satellites Budget and staffing for the Eagle satellite will continue for 2007-2008

AMSAT-NA is contributing staff and money toward completing AMSAT-DL's Phase 3 Express Satellite in 2008 AMSAT-NA teamed with AMSAT-UK to donate 25,000 Euros to AMSAT-DL for the completion of P3E

Phase IV is not a replacement program at the expense of Phase III The same transponder gear already in development for Eagle and P3E remains applicable to Phase IV The new commercial launch reality mentioned previously indicates we may actually be able to be launched earlier to a high orbit if we fit into the Intelsat ride sharing model We need to be ready for this event

Phase IV will enable AMSAT to concentrate more fully on the development of space communications The Intelsat platform will provide hundreds of watts of power for 15 years eliminating the need for AMSAT to provide solar cells, it will perform the station keeping and earth pointing tasks, internal housekeeping will be simplified

Once we have shown funding sources what AMSAT is capable of additional launch opportunities will arise Intelsat can drop off sub-payloads into LEO, GTO, or GEO orbits on their way to their primary mission There are more doors open to the future if we realize and pursue the new reality

I invite you join AMSAT's exciting future As we recognize and work within the new reality of commercial spaceflight we will provide exciting new services for amateur radio, emergency preparedness, and education The side effect of developing "services" will be that we still gain what everyone is asking - high orbit transponders for us to use and enjoy AMSAT is to satellites what the Wright brothers were to flight We are "Amateur" only in the sense that we are not paid in much the same sense that Olympic athletes are "Amateurs "
