The Israeli-built GURWIN-1 Techsat and the Mexican UNAMSAT were part of the payload of a Russian SS-25 rocket originally built to carry ballistic missiles and recently converted to launch satellites. The Reuters News Agency said the rocket, which was launched from Russia's Plesetsk Cosmodrome, came down in the Russian Far East, in the Sea of Okhotsk, on March 28. Both satellites were designed for packet radio repeater use. GURWIN-1 Techsat was built at the Technion-Israel Institute of Technology in Haifa as a 9600-bit/s packet store-and-forward satellite. UNAMSAT was assembled by students at the Universidad Nacional Autonoma de Mexico (UNAM) in Mexico City. In addition to packet store-and-forward operation at 1200 bits per second, UNAMSAT carried a unique "meteor radar" experiment. Reuters noted that the 115-pound GURWIN-1 Techsat was a prototype for communication satellites and "was to have been used by amateur radio enthusiasts." Reuters did not mention UNAMSAT. Two Russian satellites also were lost in the failed launch. In November 1993 the first test launch of a converted SS-25 was successful, but with a lighter payload. Radio amateurs, particularly in Europe, have hoped that the Russian rockets will provide an inexpensive way to launch amateur radio satellites. [Info via ARRL] * SOFTWARE ANNOUNCEMENT * ========================= March 31, 1995 SatTrack V3.1 has been released. SatTrack is a satellite orbit prediction and realtime tracking program with X Window System color graphics displays. The program has been written in C language and runs on a number of different Unix and Linux systems with X11R5. It not only displays in realtime where a number of satellites are but is also capable of controlling suitable ground station equipment, like antennas or optical telescopes, and radio communications hardware. In the autotrack mode it switches between various satellites as they rise and set. Predictions of passes of satellites over specified ground stations can be run off either interactively or in batch mode. For detailed on-line information check the new SatTrack WWW Home Page at http://ssl.berkeley.edu/isi_www/sattrack.html The distribution file sattrack-3.1.tar.gz (or sattrack.V3.1.tar.gz) is also available from: ftp.amsat.org/amsat/software/Linux ftp.jnvc.net/priv/kupiec/sattrack [Info via Manfred Bester (manfred@ssl.berkeley.edu)] * MIR NEWS * ============ Miles, WF1F, reports that he had a nice chat with Astronaut Norman E. Thagard on the Mir space station on 31-Mar-95. Norman is trying to get on the air as much as possible to chat with people, but there are a lot of stations calling him out of turn. This is causing lots of interference. Miles suggests that stations wanting to talk with Norman should wait until he is done talking to the specific station after which he will make the announcement "CQ". Astronaut Norman is not a "Contester". He likes to chat with each station for a 3 to 5 minutes before going on to the next station. Please respect his chosen QSO format. Norman said the Russian crew is not keeping any type of call log, but if you talk with Norman, he is keeping a log and will try to send you a response card. Note, however, that he will not be sending cards until after he returns to earth with his log book. Norman Thagard's QSL address is as follows: NASA Lyndon B. Johnson Space Center Norman E. Thagard Mail code CB Houston, Texas 77058 The Mir PMS packet station is working again, but some of the TNC parameters are incorrectly set. One of the bad parameters is the TX-Delay. This is preventing most stations from reliably connecting, unless conditions are ideal. Dave Larsen N6JLH, is currently working with Norman Thagard to fine tune the PMS parameters. It is requested that stations not try to access the PMS Packet until all of the parameters on the Mir PMS have been properly adjusted. The work should be completed by April 7th. * FEEDBACK/INPUT WELCOMED * =========================== Mail to SpaceNews should be directed to the editor (John, KD2BD) via any of the following paths: FAX : 1-908-747-7107 PACKET : KD2BD @ KS4HR.NJ.USA.NA INTERNET : kd2bd@amsat.org -or- magliaco@pilot.njin.net SATELLITE : AMSAT-OSCAR-16, LUSAT-OSCAR-19 MAIL : John A.
