UoSAT-12 Receives OSCAR Number

UoSAT-12, amateur radio's newest satellite, will also officially be known as UoSAT/OSCAR 36, or simply UO-36. The satellite carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders. OSCAR 36 will soon complete its first full month in orbit.

Responding to a question from Keith Baker, KB1SF, President of AMSAT-NA, representatives of the UoSAT team requested that an OSCAR number be assigned to help designate their new spacecraft.

The assignment of consecutive OSCAR numbers to new amateur radio spacecraft is a tradition that dates from the launch of the very first Amateur Radio Satellite - OSCAR-1. In order for an OSCAR number to be assigned, the satellite must successfully achieve orbit and one or more transmitters must be successfully activated in the amateur radio bands. Then, the builders/owners of the satellite must formally request that a consecutive OSCAR number be assigned to their satellite once the first two requirements are accomplished.

Speaking for the UoSAT team, Chris Jackson, G7UPN, told AMSAT and ANS that "we would be honored if UoSAT-12 could be recognized as an OSCAR satellite, and suggest the designation UoSAT-12/OSCAR 36, abbreviated UO-36, be used."

KB1SF has informed ANS that, in the light of this information, it is now appropriate to refer to the new amateur satellite as OSCAR-36 or simply UO-36. President Baker added "I am personally looking forward to the unique on-orbit capabilities that this satellite will bring. Our sincere thanks to the UoSAT team for a job well done!"

The satellite remains in very good health. The in-orbit commissioning of the mini-satellite achieved another important milestone recently. On May 2nd, the newly developed 'Space GPS Receiver' (SGR) was operated for the first time on UO-36. The SGR is a 24-channel GPS receiver jointly developed by Surrey Satellite and the European Space Agency (ESA). It is designed to enable both orbit and attitude determination in addition to providing a precise on-board reference clock. Martin Sweeting, G3YJO, tells ANS that "from an autonomous start with no prior knowledge, the receiver was able to achieve a very accurate orbital position fix for UO-36 in under seven minutes." Positioning data was continuous over the five hours of test operation in orbit, with the SGR tracking a number of GPS satellites simultaneously. A more detailed analysis will be undertaken during upcoming tests.

Experimentation also continues with the development of rapid initialization procedures and the operation of multiple antennas on the spacecraft.

Further information about the satellite is available at the following URL: http://www.sstl.co.uk/

Donald Stoner, W6TNS

ANS is saddened to report that the man who first conceived of Project OSCAR, Don Stoner, W6TNS, of Clearwater, Florida died May 4th. He was 67. Stoner reportedly had been in ill health for some time and reportedly suffered a ruptured aneurysm.

In 1960, Stoner, then living in California, was the idea man behind Project OSCAR. Stoner outlined his concepts for an Amateur Radio space program in the February 1961 issue of QST. In his prophetic article, Stoner envisioned a two-phase project, the first to launch an orbiting VHF beacon transmitter into space, the second to launch an 'orbital repeater'.

OSCAR 1 was launched December 12, 1961.

An ARRL member, Stoner also will be remembered as a CQ columnist.  He served in several editorial capacities including VHF editor, Novice editor, surplus columnist and semiconductor columnist. Stoner also wrote the 'In Theory' column in CQ-VHF magazine during 1996 and 1997.

ANS sends the sympathy of the satellite community to his wife Lucy and family.

AMSAT at Hamvention

AMSAT-NA Vice President for Field Operations, Barry Baines, WD4ASW, reminds ANS that the Dayton Hamvention is quickly approaching, scheduled for May 14-16, 1999.

AMSAT-NA will again be represented in booth spaces 445-448. AMSAT volunteers will help handle the myriad of activities that typically occur at an AMSAT booth; handle transactions, deal with memberships and renewals, answer questions and serve as representatives of AMSAT-North America.

WD4ASW reports he expects to have a very busy booth this year with all the normal AMSAT publications and a variety of updated and new items:

Barry is looking for volunteers to help man the AMSAT booth at the Hamvention. Contact WD4ASW at wd4asw@amsat.org for details.

AMSAT-NA will be involved with several interesting and important satellite-related presentations on Saturday, May 15, 1999. Scheduled events start at 08:15 in Room 3. Presentations will include:

Check the official Dayton Hamvention program for official starting times of each forum. Please note that the AMSAT forums will be held in the main Exhibit Area and not offsite.

Other Dayton/AMSAT activities include the AMSAT Dinner on Friday evening at the Amber Rose Restaurant.

ANS hopes everyone enjoys Hamvention and the related AMSAT festivities!

Listeners to OSCAR-11 may be interested in visiting the G3CWV web site. The site contains details of the hardware and some software for capturing OSCAR-11 data and decoding ASCII telemetry and WOD. There is also an archive of raw data (mainly WOD) for analysis, which is continually expanded as new data is captured. Audio files are also included with examples of each type of data transmitted by the satellite (each one plays for about ten seconds). Examples of mode-S reception can also be found at the site. All the audio files are zipped so that they can be played off-line. The URL is http://www.users.zetnet.co.uk/clivew/

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.

SunSat SO-35

Uplink/downlink frequencies have not been established.

The satellite is not currently available for uplink transmissions.

Hans, ZS5AKV, reports that SunSat is still in the initial test stages and the command team will provide more information as it becomes available. General amateur radio service is planned for the near future.

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.
