AMSAT Jewelry Contest

With preparations for the 17th Space Symposium and AMSAT-NA Annual Meeting in San Diego well underway, Dave, WB6LLO, informed ANS that the 7th Annual AMSAT Jewelry Contest, a long time favorite during past Symposiums, will again take place this year.

Dave tells ANS that although San Diego is well known for its air and sea military presence, satellite operators worldwide feel that the "pen is mightier than the sword -- hence, the 'Pen-tenna' will be the jewelry contest piece this year."

According to WB6LLO, think of the 'Pen-tenna' as "desk jewelry." The 'Pen-tenna' is a very ordinary style inverted-V antenna constructed from two stainless and gold plated Parker pens. The pens are removable and usable. The 'elements' are 6-15/32" long and a nominal 9/32" in diameter. They subtend an angle of 108 degrees. A modified BNC tee provides a connection for the 'elements'. Copper and brass tubing form the penholder/element attachment. The modified BNC is encapsulated in a cast resin base that is about five by six inches in size. Various IC's are 'floating' in the base along with an AMSAT logo.

The contest is to determine the resonant frequency of the 'Pen-tenna'! According to WB6LLO the "frequency band is obvious, but the exact frequency will determine the winner."

"The person who determines the exact frequency in megahertz will be declared the winner, and the winner will be announced at the Symposium banquet," said WB6LLO. Attendance at the banquet or the Symposium is not a requirement to win; anyone can enter -- but only one entry per person is allowed.

If not attending the Symposium the deadline for an official entry is 1-October-99. For those attending the Symposium the deadline is 1500 UTC on Saturday, October 9th.

2001 Launch Planned for Canadian Satellite

(Please note - portions of this story are used with permission of the Toronto Star newspaper)

From the very beginning, Canada's next-generation satellite has been audacious. It's no larger than a microwave oven, yet it will tackle a scientific controversy of cosmic proportions -- the age of the universe -- using the world's smallest space telescope. It's scheduled to be launched by the end of 2001, although not one circuit board has yet been put together. And the outside experts advising on the satellite design and construction are all amateurs.

But the most audacious part may be the birthplace. This quick, cheap and small marvel was conceived and is being nurtured in a bursting-at-the-seams suite of second-floor offices, up the stairs next to a Japanese restaurant. Welcome to Dynacon Enterprises Ltd., where cutting-edge technology beat out two bidders to get the nod from the Canadian Space Agency for the first in Canada's planned series of science micro-satellites. The satellite is called MOST, an acronym for Microvariability and Oscillations of STars project.

"The small satellite field is growing while the large satellite field is shrinking," says Kieran Carroll, Dynacon's manager of space projects and MOST sparkplug. "We are thinking very much about defining the market niche where we can compete and excel."

Dynacon has its eye on the full program of as many as 10 micro-satellites that the Canadian Space Agency is planning. And it has an unexpected partner in this ambitious plan - the University of Toronto Institute for Aerospace Studies.

At the institute, Robert Zee shows a visitor around a modest construction zone that will soon become the test and assembly area for the satellite and, eventually, also house the main ground station. "We're quite excited about MOST," he says.

So are the graduate students here, most only a few years younger than Zee, who manages the space flight laboratory. The institute is already the only place in Canada to study spacecraft design and it's now about to add hands-on spacecraft construction to the curriculum.

Inside the 50-kilogram suitcase satellite is the world's smallest space telescope, with an aperture only a little bigger across than a CD. It is supposed to keep the same star in sight for at least seven weeks so a super-sensitive light meter can record variations in brightness as faint as one part in a million.

The crucial expertise in fine-tuning the satellite is being provided free of charge by, of all people, ham radio operators. Not just any old operator, however, but ones who have had a hand in designing and building more than three dozen satellites since the 1960s. Quietly, with minimal recognition, the U.S. volunteers in the Radio Amateur Satellite Corporation have charted the technological path for today's constellations of commercial communications satellites.

About a dozen of the American amateur satellites are still operating today, acting as orbiting repeater stations for ham operators. And many more are in orbit built by Russian radio amateurs.

As the American operators proudly point out, they did it cheaply by keeping it simple. The flexible steel used for carpenter's rules springs out into antennas on their satellites. Surplus stores are scoured for suitable electronic components. "What we teach are ways of doing things, ways of thinking about spacecraft design," says Keith Baker, North American president of AMSAT the abbreviation for the non-profit corporation.

The radio operators share their expertise for two reasons. Education is part of the corporation's mandate and students often support the cause after graduation.

And if there's a tiny corner available, the ham operators will be allowed to tuck an amateur radio package into MOST.

TEPR 4 is 24
TEPR 5 is 60

This means that the transmitter will turn on 12 minutes after it enters the sun and shut off 18 minutes later.

Mike, N1JEZ, reports working CU3/DL7VTX and EB4DKA via AO-27.

Look for John, N8QGC, operating from St. Thomas, U.S. Virgin Islands and from Puerto Rico as KP2/N8QGC and KP4/N8QGC later this month.

KM4NZ tells ANS that AO-27 "has exceeded it design life cycle and the control team is going to give it a physical to see how healthy it really is."

AO-27 is seeing heavy usage, especially on weekends.

KITSAT KO-23

Uplink 145.850, 145.900 MHz FM
Downlink 435.175 MHz FM, 9600 Baud FSK

Not operational. The downlink transmitter has not been operational for any normal communication.

ANS has learned (from the KO-23 ground command team) that satellite downlink telemetry shows one of KO-23's battery cells to be very unstable. HL0ENJ reports that KO-23 is in continual sunlight though 19-March and they are downloading battery information from the satellite using a synchronous 1200 baud data flow during each pass.

Bill, VK3JT, reports the last data he downloaded from KO-23 was on 17-January. Passes this week have the downlink signal at S-8 with no data. Rick, KB0VBZ, also reports good signal strength but no data from the satellite.

HDLC telemetry framed so a TNC in KISS mode will decode it

Unknown status. ANS has not received any recent updates concerning the current status of GO-32 and no additional information is available at this time.

The TechSat-1B micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998.

The satellite does not have a continuous beacon, but does transmit a 9600-baud burst every 30 seconds (for about 3 seconds in length), currently on 435.225 MHz.

The TechSat team has also constructed a home page about the TechSat bird. To view the site, point your web browser to:

SEDSAT SO-33

Downlink 437.910 MHz FM 9600 Baud FSK
The satellite is not currently available for uplink transmissions.

Recovery efforts have been unsuccessful. The chances of SedSat-1 reaching full operational status is doubtful.

SEDSAT-1, signifying Students for the Exploration and Development of Space Satellite number one, was successfully launched and placed in orbit on Saturday, October 24, 1998.

Dennis, KD4ETA , reports SedSat is continuing to perform as it has since launch, transmitting telemetry until the batteries are depleted and then going into safe mode -- then repeating the process. Dennis reports the satellite downlink has been active for over four months of the stated minimum design life of six months. "It is just too bad we have problems with the receivers or we would have such a beautiful bird," said KD4ETA.

Dennis further noted "in my opinion we can claim now at least partial victory for our satellite. Most of the engineering goals have been met, but it is just a total shame that the imaging system has not been able to fulfill its mission due to the probable loss of both receivers."

PANSAT PO-34

Downlink frequency not established.
The satellite is not currently available for uplink transmissions.

PANSAT, developed by the Naval Postgraduate School, was launched from the shuttle Discovery. PANSAT spread-spectrum digital transponders will be available to amateur radio operators in the near future along with software to utilize this technology. The PO-34 command station is located in Monterey, California.

Dan Sakoda, KD6DRA, PANSAT Project Manager recommends 'The ARRL Spread Spectrum Sourcebook' as a good place to start in understanding the spread-spectrum scheme.

The PANSAT Team does not expect the satellite to be available to the Amateur Radio community for another few months.

SunSat SO-35

Downlink frequency not established.

The satellite is not currently available for uplink transmissions. At this time the command team is planning general amateur radio service by the end of March.

SunSat was launched February 23, 1999 aboard a Delta II rocket from Vandenberg Air Force Base in California. SunSat stands for Stellenbosch University Satellite and takes it name from the South African university whose students constructed the payload.

The SunSat package includes 1200 and 9600 baud digital store-and-forward capability and a voice 'parrot' repeater system that will be used primarily for educational demonstrations. The satellite has two VHF and two UHF transmit-receive systems.
