UoSAT-12 Successfully Launched

Chris Jackson, G7UPN, reported to ANS that UoSAT-12 -- amateur radio's newest satellite -- was successfully launched on April 21, 1999 from the Russian Baikonur Cosmodrome. The launch took place just before 05:00 UTC and according to Chris, confirmation of stage separation was first received, followed with orbit insertion of UoSAT-12 taking place at just over 14 minutes into the flight.

The launch is the first mission for the former Soviet Union's arsenal of SS-18 ICBM missiles, all of which have to be destroyed or used for peaceful purposes under the START arms reduction treaty.

UoSAT-12 is the latest amateur radio research satellite from the University of Surrey. The bird carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders.

Launch congratulations were received from many satellite operators, including Andy, WD9IYT, who passed on good wishes to the UoSAT team, hoping "the check-out phase goes well too."

AMSAT-NA President Keith Baker, KB1SF, noted the proud heritage carried into orbit by the new satellite in his message to the UoSAT team:

"On behalf of AMSAT North America, please accept our sincere congratulations on the successful launch and activation of UoSAT-12. As with the numerous other UoSATs that have gone before, I'm confident that this new satellite will prove just as capable and just as exciting for the world's Radio Amateurs". -- Sincerely, Keith Baker, KB1SF

Operators at the Surrey Space Center ground station reported to ANS that following the launch, UoSAT-12 has successfully passed all initial tests, including enabling the on-board and essential bus subsystems. In addition, the command team successfully uploaded flight software to the satellite's primary on-board computer. This multi-tasking software will collect telemetry throughout the satellite's orbits, supporting the attitude acquisition phase of the mission. During this phase on-board software will gradually bring the satellite to an Earth-pointing state, followed by payload testing. G7UPN reports the BBS is closed for general use at this time "although the downlink is on permanently so stations can receive it."

The satellite has been transmitting 9600 baud FSK telemetry framed in a VLSI format using a downlink frequency of 437.400 MHz. Reception reports were received almost immediately following the launch. Richard, G3RWL, reported hearing UO-12 with variable signal strength. Kazu, JJ1WTK, told ANS that the signal from the new satellite was very strong. Mark, K0MDJ, reported "the new satellite was loud with solid copy, it's good to see it looking healthy!" Other reception reports were received from JE9PEL, VE7AHX, KB0VBZ, DB2OS, VK5AGR and LW2DTZ.

According to G7UPN, a dedicated UoSAT-12 web site with more information will soon be available. In the interim, preliminary UoSAT-12 data can be found at

Mir School Contact

Recently, during the 'Mir School Club Roundup', several students from Unicoi County Area Vocational High School in Erwin, Tennessee experienced a unique learning experience by participating in a special experiment that involved the Russian space station and amateur radio.

Bob Thomas, KS4NG, tells ANS that the welding classes at the school constructed a small, four element VHF antenna "with the hopes of making contact with Mir." The students also learned how to use a computer for tracking Mir as it passed over North America and a communications software package for transmitting APRS packet messages to Mir and digipeating through the station, all under the direction of KS4NG.

The experiment at the school was successful each day the students tried. The students had to aim the antenna as Mir passed overhead, track the space station during the pass and then confirm their APRS packets were received and retransmitted. Many schools in North America (along with satellite operators across the country) monitored the event and reported each station's success by e-mail. UCHS received reports from as far away as Spokane, Washington and Annapolis, Maryland.

In addition, the students learned how to use APRS software, putting a symbol of a school building on computer maps showing exactly where UCHS was located.

ANS congratulates students Diana Boone, KF4FLT, and Josh Bryant, KF4JMU, along with all the UCHS students that took part in the Mir School Club Roundup.

HSCW Contest

The Western States Weak Signal Society (WSWSS) is sponsoring the Second North American High Speed Meteor Scatter (HSMS) Contest to promote the development of skilled HSCW operators in North America.

Many satellite operators can (and have) used their satellite stations to explore this interesting mode.

The objective of the contest will be to contact other amateur radio stations via meteor scatter during the contest period (using HSCW) on amateur radio bands above 50 MHz.

The contest will run from 00:00 UTC on May 1st, through 24:00 UTC on May 9, 1999. Stations may operate up to 48 hours during this time period. Random and scheduled contacts count for contest credit. Several classes and power limit categories are available.

Certificates will be awarded to the top three stations overall, and to the highest scoring station in each USA/VE call district for each category. In addition, a certificate will be awarded to the highest scoring portable station.

Additional information about the contest -- and HSCW operation in general -- is available on many of the HSCW web sites, including

Several stations are experimenting with PSK31 via AO-10. KD7MW, WB4APR, K7RR, W4SM, DB2OS and DL6DBN have been posting information about this new mode on the AMSAT-BB. The May QST has a good article on PSK31. KD7MW reports some success with using this mode (contact Peter at if you're interested in trying a PSK31 QSO). Mike Seguin, N1JEZ, ANS principal satellite investigator, has recently downloaded the PSK31 software and will be trying this new mode.

Tony, AB2CJ, has been transmitting SSTV via AO-10. Jim, AA7KC, reports an AO-10 contact with veteran satellite operator Stan, W0IT. Jim reports the satellite signal varied from S-7 to noise. "Performance is useful if you communicate between the deep fades," reports AA7KC. Jerry, K5OE, confirms recent reports regarding AO-10's improving   behavior, recently working DC3ZB and OZ1MY with 5x5-5x7 signals. Jerry reports the QSB is down from even a week ago.

Masa, JN1GKZ, reports his web page shows the current AO-10 spin period and spin rate (by measuring the beacon with FFTDSP software). JN1GKZ tells ANS AO-10's spin period is decreasing rapidly, by about 5 seconds each week. The current spin period has reduced from 115 seconds to 124 seconds. The web site also shows the FMing of the beacon, however, Masa reports no fluctuation of the beacon on April 24th. The JN1GKZ web site can be found at

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

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.
