RS-17 Declared Dead

It's official. The Sputnik PS2/RS-17 mini-satellite ceased transmitting on December 29, 1997. The little satellite, a one-third scale replica of the original Sputnik 1, beep-beeped its way around the globe for 55 days, more than two weeks longer than it had been projected to last. The 100-mW transmitter was powered by lithium batteries.

The Sputnik PS-2 was launched by hand from the Russian Mir space station on November 4, 1997, to commemorate the 40th anniversary of the launching of the original Sputnik by the USSR in 1957. The original Sputnik only transmitted for about one month.

The Sputnik PS2 beacon, on 145.82, was widely monitored and recorded around the world. The satellite was fabricated by students in Russian and on France's Reunion Island. Sputnik 40 Years, which sponsored the satellite project, said the last known recordings of the Sputnik PS2 beacon were made on December 29 at approximately 2100 UTC by a ham in Washington and by FR1AJ on Reunion Island. At the time, the data indicated an internal temperature of 40 degrees Celsius.

Those tracking the satellite reported that the Sputnik PS2's beacon signal had continued to get weaker as the end approached. Even after the beep-beep ceased, however, the satellite's unmodulated oscillator continued to transmit for a while longer.

Reception reports go to The Radio Club of Jules Reydellet school on Reunion Island. Those whose reports are confirmed will receive an approximately 6x9-inch color certificate on high-quality paper with number identification and the radio club stamp. Requests for these certificates should be made only by letter with an SASE (6x9 inch) and two (2) IRCs. Do not send requests via e-mail. The mailing address is

Mir's Life Extended

The 12-year-old Russian Mir space station may stay in orbit until the first components of the International Space Station are in place in 1999. That's a few months longer than Mir was supposed to stay up. The first ISS units are set to be launched later this year. Hams are scheduled to be among the first crew members to populate the ISS, but the US presence aboard Mir comes to an end this June.

Us astronaut David Wolf, KC5VPF, now aboard Mir, is scheduled to be replaced later this month by Australian-born US astronaut Andy Thomas, KD5CHF. Two new Russian crew members, both hams, are due to arrive at month's end. The Russian cosmonauts are Talgat Musabayev, RO3FT, and Nikolai Budarin, RV3FB. Wolf has been on Mir since late September. Thomas will work aboard Mir until June.

Wolf's research schedule has allowed him little spare time to use the ham radio equipment aboard Mir. The packet system aboard the space station has been experiencing problems because the crew has not had time to set up the correct parameters for the new TNC aboard Mir. This week, Wolf, 41, monitored and filmed operations from inside Mir's main module as his two cosmonaut crewmates conducted a space walk to check a leaky hatch and to retrieve some equipment. On January 14, Wolf and cosmonaut Anatoly Solovyov will do a spacewalk to recover some experiments.

Mir

American astronaut David Wolf, KC5VPF, will be replaced by Andy Thomas, KD5CHF, During the January STS-89 Mission. The PMS 2-meter radio station was temporarily moved from the core module and installed in the Priroda Module. This move was performed to take advantage of the backup antenna. The crew also installed a new modem a few weeks ago. But due to the crew's heavy work load, all of the TNC parameters have not been properly configured. Mirex would like the stations monitoring the PMS to please be patient while they make adjustments. The PMS is NOT fully operational at this time.

During the recent space walk, the crew was planning on examining the primary PMS antenna located on the Mir-core module, if time permits. The crew suspects there may be a loose coax cable to the primary PMS antenna. If the antenna checks out fine, the crew will still leave the PMS station connected to the backup antenna until the March time frame. This is because the crew will be very busy with many other experiments and will not have much time for a low priority experiment such as the PMS.

The only limitation they have with the current backup antenna, is the Diplexor filter which is required for the SAFEX and PMS to share the same antenna. This would prevent any 70 cm experimentation from the Kenwood TM-733.

SAFEX, Mir 70cm Repeater

(Uplink 435.750 MHz FM, Downlink 437.950 MHz FM, Subaudible tone 141.3 Hz)

During last week's momentary Mir attitude control computer shut-down, the Mir crew temporarily shutdown the Amateur Radio station for a few days. The PMS system was turned back on, but it is not known when the crew plans on turning on the SAFEX Repeater.

MIREX has created an Internet Web page containing information regarding Mir and the various Amateur Radio experiments taking place from the space station. The pages are still "under construction", but some good information can be gathered from what has been put together. URLs include the following:

FO-20

(Uplink 145.9-146.0 MHz CW/LSB, Downlink 435.8-435.9 MHz CW/USB)

Operational. FO-20 in mode JA continuously.

FO-20, like many LEO's is in a "sun synchronous" orbit. The precession in the RAAN of its orbit due to the earth's oblateness matches the earth's rotation around the sun so that FO-20 always has about 33 minutes of eclipse time each orbit and the rest in sunshine. A sun synchronous orbit is a retrograde LEO polar orbit with an inclination of about 98 degrees. At this inclination RAAN precession = 360 degrees in 365 days. The stability in temperature and solar energy is, needless to say, very helpful. The ratio of eclipse to sunlight can be adjusted by varying initial orbital elements. FO-29, for example, is virtually always in sunlight, UO-11 has about 22 minutes of eclipse, most seem to run about 33 minutes eclipse per orbit.

This also means that FO-20 (and other sun synchronous sats) appear at your location at about the same "sun time" every day. At my QTH FO-20 goes over about 1:30 PM and 3:30 PM every day. UO-11, AO-16, DO-17, WO-18, LO-19, UO-22, KO-25, AO-27, FO-29 etc are also in sun synchronous orbits. KO-23, RS-12/13, RS-15, though in highly inclined orbits, are not sun synchronous.

Operational.

OSCAR-11

(Downlink 145.825 MHz FM, 1200 baud PSK. Beacon 2401.500 MHz.)

Operating normally.

The operating schedule is unchanged.

Transmission Duration
ASCII status 210 seconds
ASCII bulletin 60 seconds
Binary SEU 30 seconds
ASCII TLM 90 seconds
ASCII WOD 120 seconds
ASCII bulletin 60 seconds
Binary Eng 30 seconds

There are also additional status blocks after each bulletin is transmitted, and between ASCII TLM and WOD.

The mode-S beacon is ON, transmitting an unmodulated carrier, but telemetry indicates that it has partially failed, and delivering half power. This beacon is a useful test source for those testing mode-S converters, prior to the launch of P3-D. It is considerably weaker than DOVE, which should be used for initial testing. Any reports of reception on 2401 MHz would be most welcome. Please e-mail reception reports to g3cwv@amsat.org.

The 435.025 MHz beacon is normally OFF. However it can sometimes be heard when the satellite is being commanded by ground control, (i.e. within range of Guildford, Surrey, UK). When the 435 beacon is transmitting, the 145 beacon is normally OFF. The data transmitted is mainly binary.

OSCAR-11 users are welcome to visit the G3CWV web site. It contains some software for capturing data, and decoding ASCII telemetry and WOD. There is an archive of raw data (mainly WOD) for analysis, which is continually being expanded, as new data is captured. The URL is http://www.users.zetnet.co.uk/clivew/.
