Satellite Pioneer K2ZRO to be Honored

The Kopernik Observatory located near Binghamton, New York celebrated the observatory's 25th anniversary over the weekend with a special event amateur radio station that also honored the memory of one of the observatory's founders - Kaz Deskur, K2ZRO.

Kaz Deskur died in 1984. Deskur's widow and family attended as honored guests along with keynote speaker Dr Joseph Dervay, a NASA astronaut-physician.

Amateur Radio club station KB2UYF is located at the observatory, and paperwork has been submitted to the FCC to change the station's call sign to K2ZRO.

Deskur was a satellite pioneer who operated the observatory's ham station under his call sign for many years. In the early days of the OSCAR and AMSAT programs, K2ZRO was a familiar call sign on many satellites. Kaz designed the original OSCAR-LOCATOR, a device many 'old-timers' used to track a satellite before the advent of personal computers and software tracking programs. For many years AMSAT sponsored an engineering award in Kaz Deskur's honor.

The Kopernik Observatory is establishing a special 'Wall of Honor for Amateur Radio Satellites' to honor Kaz Deskur. All hams that knew or worked with him are invited to send their QSL cards for display on this wall. QSL cards may be sent (in an envelope) to:

  Kopernik Space & Science Education Center
  30 Front Street
  Binghamton, NY  13905

Hams at Kopernik also will be active on June 19th, hoping to make many contacts during the ARRL's Kid's Day even, with operation planned on several satellites including FO-20 and AO-27.

1999 Digital Communications Conference

Many digital satellite operators will be on hand in Phoenix, Arizona this September for the 18th annual ARRL and TAPR Digital Communications Conference.

TAPR's Greg Jones, WD5IVD, will chair this year's conference.

The conference is an international forum for radio amateurs in digital communications (including via satellite), networking and related technologies - to meet, publish their work and present new ideas and techniques for discussion.

Conference highlights include a full day of papers, breakout sessions and selected topics for the beginner to advanced amateur digital enthusiast.

Symposiums will include the latest in APRS information moderated by Steve Dimse, K4HG, and featuring satellite regular Bob Bruninga, WB4APR. The Saturday banquet will feature Geoff Baehr, N6LXZ, Sun Microsystems chief network officer as guest speaker.

Full information on the conference is available at the following URL:

SAREX Mission Nears

As the International Space Station mission of STS-96 draws to a very successful close, thoughts now turn to the next SAREX mission, STS-93. This mission is tentatively set for a late July launch and is scheduled to include both voice and packet operations.

AMSAT Vice President for Human Spaceflight, Frank Bauer, KA3HDO, tells ANS that currently the International ARISS team is busy with the development and qualification of hardware for ISS. The team will be delivering the first ham equipment (the Initial Station) to NASA this July for launch on STS-101 in December.

Initial Station hardware is being built and qualified by a multinational team with members from Russia, Italy, Germany and the United States. KA3HDO tells ANS that he is "quite proud of the international cooperation that is occurring to bring all this hardware to flight status."

Meanwhile, ARISS team member Will Marchant, KC6ROL, reports that five schools are currently scheduled to have dedicated contacts with the crew of STS-93. Crewmembers are also expected to support random voice contacts and packet operations on 144 MHz.

Downlink 145.825 MHz FM, 1200 baud PSK
Beacon 2401.500 MHz

During the period 15-April to 15-May reliable signals have been received from the 145.826 MHz beacon. The battery voltage during daylight passes has continued to decrease. The internal temperatures have continued to fall, by about two degrees C during this period, due to the increasing eclipse times.

The magnetorquer spin correction counters have now started to show some activity. During the last month the negative spin counter has started to increment at about three counts per day - previously it was incrementing at about one count every three days.

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.

For more information on SunSat, visit the following URL:

Ground control stations have received images from the PAL-TV imager on SunSat. The imager is a commercial grade TV camera connected to the S-band transmitter.

UoSAT-12 UO-36

Uplink/downlink frequencies have not been established.

The satellite is not currently available for general uplink transmissions.

UoSAT-12 was successfully launched on April 21, 1999 from the Russian Baikonur Cosmodrome. UO-36 carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders.

G7UPN reports that due to the increase in satellite temperature over the past several days the 437.025 MHz 38k4 downlink is off again. "This transmitter is generating too much heat now that the satellite is in continuous sunlight. Hopefully over the next few days we will change the attitude mode of the satellite and we'll then be able to put the transmitter back on," Chris told ANS.

Further information is available from:

[ANS thanks Chris G7UPN/ZL2TPO, and the University of Surrey, for this information]

The following satellites are in orbit but are non-operational at this time:


The 435 MHz beacon (only) is operational. Attempts to command the mode A transponder 'on' have been unsuccessful to date.
