SUNSAT Launched

ANS is pleased to report that on February 23rd, after more than a month of delays and aborted launch attempts, the Delta II rocket carrying the South African SunSat Amateur Radio satellite successfully lifted off from Vandenberg Air Force Base in California.

From the launch site, Cliff, K7RR, (via John, W7RAQ) first reported the good news to ANS:

"Success at last! The rocket carrying SunSat was launched this morning. The launch was a spectacular sight with the rocket lifting straight up, heading slightly west then turning south before disappearing from visual sight."
--K7RR

Following the launch, the AMSAT-BB was active with congratulations for the SunSat team. KD6PAG first reported receiving the downlink, noting "the bird was S-9 at times." John, G0ORX, passed on "congratulations to Sunsat!" Phil, KA9Q, reported seeing the launch from the front of his house in San Diego. KA9Q told ANS that he "picked up the yellow SRB plumes about a minute after launch as it rose above the usual low elevation haze."

Shortly after launch, AMSAT-NA President, Keith Baker, KB1SF, issued the following release:

"On behalf of AMSAT-NA, please pass along our sincere congratulations on the successful launch and activation of SUNSAT in orbit. I know there are many hams around the world who have been patiently waiting for the launch of this satellite and I am personally looking forward to the unique on-orbit capabilities that it will bring to us. Once again, our sincere congratulations and thanks to all the SunSat team for a job well done!"
--KB1SF

SunSat, which stands for Stellenbosch University Satellite, takes its name from the South African university whose students constructed the payload. The University of Stellenbosch, situated in the second oldest town in South Africa, is not far from the southern tip of the African continent just east of Cape Town. The university has in excess of 14,000 students.

The SunSat package includes 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. Current downlink activity from SunSat is on 436.250 MHz, using a FSK Bell 202 format at 1200 baud. A complete description of SunSat (along with photographs) is available in the September/October 1998 issue of The AMSAT Journal.

The SunSat command team, headed by Garth Milne, ZR1AFH, reported signals were received from the new satellite during the very first orbit. "We uplinked commands to Sunsat and were overjoyed to hear UHF telemetry start at 1200 baud, just as we wished," said ZR1AFH. However, after 12 hours in orbit, uplinking would become much more difficult, mainly because the spacecraft was still tumbling. Cliff, K7RR, reported that after making many changes including increasing power and installing new antennas on the ground, the Vandenberg command team received loud and clear return signals from the bird. Ground control at Stellenbosch University is now currently busy with the commissioning of the satellite, including deployment of the gravity boom to help stabilize the bird.

During the commissioning phase, amateurs are kindly requested to avoid using SunSat uplink frequencies. The SunSat downlink will only be active when the satellite is within range of the ZS1SUN groundstation. Amateurs are invited to monitor or record these telemetry downlinks.

At this time the command team is planning general Amateur Radio service by the end of March.

It's 30 Years for AMSAT-NA

In 1969 the thought of an organization to build, fly and operate Amateur Radio satellites was just that -- a thought -- and from humble beginnings The Radio Amateur Satellite Corporation, known as AMSAT -- was born. Now, 30 years later, AMSAT North America, along with many worldwide partners, shares an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites.

AMSAT-North America will celebrate its 30th anniversary on March 13, 1999 at the NASA/Goddard Employee's Recreation Center in Greenbelt, Maryland. The official festivities are slated to begin early that evening, but there will be related activities throughout the weekend including tours of the Hubble Space Telescope Center and the NASA Deep Space Communications Network. AMSAT President Keith Baker, KB1SF, and AMSAT Chairman of the Board Bill Tynan, W3XO, are planning to be in attendance. The public, along with Amateur Radio satellite operators worldwide, is cordially invited to attend.

A special patch commemorating the 30th anniversary is expected to be available at the Dayton Hamvention AMSAT booth. In addition, Rich Moseson, W2VU, CQ-VHF editor, is planning a complete 30th anniversary AMSAT story in the March '99 issue.

Information and/or reservations for the 30th anniversary celebration can be made by contacting AMSAT-NA at (301) 589-6062. Pat, WD8LAQ, reports the WA3NAN 146.835 MHz repeater will be used for "talk-in" during the festivities.

No AMSAT funds will be used for this event.

In addition to anniversary activities, AMSAT-NA is also looking forward to the 17th Space Symposium and AMSAT-NA Annual Meeting. Slated to be held in San Diego, California from October 8th through 11th, both recent and future developments in ham radio satellites will be presented in detail. More information on this event is available from AMSAT-NA headquarters or from Symposium chair Duane Naugle, KO6BT, at the following e-mail address:

ko6bt@amsat.org

[ANS congratulates AMSAT-NA on achieving 30 years, and looks forward with great anticipation to the next 30!]

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.

For more information, visit the official PANSAT web site at:
