New Mini-Sputnik Operational

Russian cosmonauts successfully launched a second mini-Sputnik satellite on November 10, 1998, during a spacewalk from the Mir space station. The launch of Sputnik 41 -- also being called RS-18 -- comes as Mir celebrates the 10th anniversary of Amateur Radio activities aboard the spacecraft. Mir, which has been home to several ham operators over the years, including several US astronauts, began ham radio operation on November 6, 1988. Over the intervening years, more than 60 cosmonauts and astronauts aboard Mir have made thousands of radio contacts with earthbound hams.

Sergei Sambourov, RV3DR, chief of the Cosmonaut Amateur Radio Department, expressed thanks "to all who have promoted and participated in ham radio communication with Mir."

The newest Sputnik was tossed by hand at the start of the spacewalk by Cosmonauts Gennady Padalka and Sergei Avdeyev. According to news reports, Padalka told Avdeyev to "toss it gently toward the moon."

Frank Bauer, KA3HDO, AMSAT-NA Vice President for Human Spaceflight Programs, speaking on behalf of AMSAT-NA and the ARISS US delegation, issued the following statement; "I want to take this opportunity to congratulate Sergei Samburov, RV3DR, Gerald Auvray, F6FAO, and the entire Russian/French team who have made RS-18 a tremendous success. I've had an opportunity to hear RS-18 since it was deployed from Mir and I must say that the signals are spectacular. RS-18 has already stimulated tremendous interest in amateur radio in space and opened the world of satellite communications to countless school children. I look forward to your continued support and participation in amateur radio's next major endeavor -- Amateur Radio on the International Space Station. Again, Congratulations!

Following the launch, the AMSAT-BB virtually became alive with reception reports. "New signals from space," said Paolo, IW3QBN, who, along with Claudio, IK1SLD, heard the new bird on the first pass after the deployment from Mir. Francisco, CT1EAT, reported "great fun" hearing RS-18 on his handheld. One of the first stateside hams to copy the junior Sputnik was Bruce, KK5DO, who caught the first pass over Texas. "It sounded great", he said, adding, "it's always exciting to hear a new satellite." Mike, N1JEZ, heard the satellite "loud and clear in Vermont", recording a portion of the pass into his computer sound card and analyzing the internal temperature-telemetry tone. Mike, WB8EJR, turned RS-18 into a family event, helping his daughter hear the new bird. Leo, KB2TIY, involved a young neighbor, Andy, in hearing the satellite, telling ANS that Andy "thinks his babysitting money may be spent getting an Amateur Radio Station together." Farrell, W8ZCF, who played a large part in analyzing signals from RS-17, also copied the new model. "Congratulations to all concerned," he said, "especially to Gerard, F6FAO, and Sergei, RV3DR. I hope this Sputnik's voices and beeps will be heard for many weeks."

Reports of Sputnik 41 being heard worldwide have been sent to ANS. Richard, G3RWL, copied multi-lingual voices and beeps from RS-18 during a pass over the United Kingdom. SP6QKP in Poland, OH8UV in Finland, DL9QJ and DH3NBC in Germany, F6FAO and F1HDD in France all reported hearing the satellite, as did VK2KUR in Australia, ZS5GMT and ZS6RSW in South Africa, KH2MH in Guam and LW5DJD in Argentina.

Stateside reception reports also flowed in. KF4KG, N1WED, KC5TRB, KK2L, N1QQV, N9YXA, N7BFS, KB4LCI, KD7MW, KC6ING, KE6ZGP, KC8CMQ and KF4TUK all posted reception reports to the AMSAT bulletin board.

Sputnik 41 is just under 8 inches in diameter and weighs almost 9 pounds. It carries a 200-mW transmitter that transmits on or about 145.812 MHz. The spacecraft has no solar cells. Its expected operational lifetime is approximately 30 days.

Bernard, F6BVP, tells ANS that he has updated the RS-18 web page, including a temperature equation and a set of unpublished photographs. His Sputnik 41 information is available at the following URL:

A computer .wav file of the actual received signal can also be found at the IK1SLD web site by pointing you web browser to:

Gerard, F6FAO, suggests the following address for RS-18 QSL requests:

  RS-18 QSL Manager
  14 bis rue des Gourlis
  92 500 Rueil-Malmaison

In addition, RS-18 temperature reports are being requested by F6FAO. Date, time in UTC, frequency of the tone, name and location should be included in the report. Stations may e-mail this information to:

Peter, DB2OS, suggests that satellite ground stations wanting to make an accurate temperature measurement using the transmitted tone from RS-18 should use the shareware 'Spectrogram' program. Peter says it runs in a Windows 95 or 98 format and is available at:

New Satellite Status

During the past few months several new Amateur Radio satellites have been launched, in addition to the recent RS-18.

The TMSAT-1 micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998. Chris Jackson, G7UPN, tells ANS that the commissioning procedure for TMSAT was recently completed. Jackson said that ground controllers are happy with the initial results, which are showing that most of the spacecraft systems are operating correctly. A minor problem has been identified with the downlink transmitter, and currently, this is limiting the use of the downlink to periods when the satellite is over Europe and Thailand. According to G7UPN, "over the coming months, ground controllers at Surrey and Bangkok will work to resolve the problem to allow the satellite downlink to be switched on over other areas. It will then be available to the general amateur community."

The TechSat-1B micro-satellite was also successfully launched from the Russian Baikonur Cosmodrome last July. The satellite does not have a continuous beacon, but does transmit a 9600-baud burst every 30 seconds (for a continuous 3 seconds in length), currently on 435.225 MHz. The commissioning procedure is continuing at this time and the satellite is expected to be available for general amateur use in the future.

SEDSAT-1 was successfully launched and placed in orbit on Saturday, October 24, 1998, flying as a secondary passenger along with the Jet Propulsion Laboratory's Deep Space One mission aboard a Delta II booster. Efforts to uplink to SEDSAT-1 are continuing with little success. The satellite has developed a major power drain problem, indicating that two primary systems, solar panels and batteries, are apparently not performing to specifications. Efforts to correct the negative power cycle problem will continue. Chris Lewicki, KC7NYV, tells ANS that for those interested in SEDSAT data, all of the received November information is now on-line at the following URL:

PANSAT, the Petite Amateur Navy Satellite recently launched from the space shuttle Discovery, is apparently alive and well as it continues to orbit the Earth. The 150-pound Amateur Radio satellite carries a spread-spectrum communication package fabricated by student officers and faculty members at the Naval Postgraduate School. Dan Sakoda, KD6DRA, PANSAT Project Manager, tells ANS two attempts to contact the satellite were recently made, and both attempts "were successful." Sakoda said that ground station modems were able to lock onto and verify PANSAT's signal and send an acknowledgment back to the satellite. Telemetry was downloaded from both passes showing that the satellite was successfully operating on its own. A commissioning plan will be the next step that ground controllers hope to accomplish.

It's Leonid Time

Astronomical anticipation will peak November 16-17th as astronomers and satellite operators around the world watch the Leonid meteor showers. Astronomers predict that an intense shower, last seen in 1966, will happen again this year. The Leonids get their name from the constellation Leo, which appears to be their source in the sky. The meteors originate from debris and dust in the wake of the comet Tempel-Tuttle. They show up on the same day every year, and approximately every 33 years, the shower can reach storm proportions.

North American viewing opportunities are not optimal this year, since our side of Earth likely will be in daylight when it passes through the meteor stream. The best viewing sites will be in China and Southeast Asia. Regardless, stateside viewing should be from around 1 AM local time until dawn, after Leo has risen in the eastern sky. The actual peak of the shower or storm lasts only a few hours and predictions vary widely.

Several professional astronomers have made elaborate plans. Avoiding any clouds is the goal of two research aircraft that will be circling above Japan hoping to record the possible meteor 'storm'. According to the Sky & Telescope news bulletin, the planes will carry various equipment including high-definition TV cameras.

Controllers of many of the satellites in Earth orbit will also be taking precautions against the cosmic debris. The Hubble Space Telescope will be aimed 'downstream' from any incoming Leonid tide, but it won't be dormant. The Space Telescope Science Institute announced that Hubble would be taking pictures of a distant quasar during the expected showers. The Goddard Space Flight Center reports that many other spacecraft will be reoriented to minimize the chances of damage.

During their recent spacewalk, the cosmonauts aboard the Russian Mir space station attached a meteorite trap on the spacecraft to collect data on the Leonid storm. While it's not believed that the storm will threaten Mir, the ARRL reports the cosmonauts will board the Soyuz escape capsule during its peak, just to play it safe.

Scientists from the NASA Space Sciences Laboratory plan to launch a balloon carrying a digital camera for a clearer view of the meteor shower. The balloon will carry an Amateur Radio package with live downlinked fast-scan ATV on 426.250 MHz. Both still images and low-resolution television captured by the on-board camera will be available online during the flight, at the Space Sciences Laboratory Web site:

Shelby Ennis, W8WN, tells ANS the 'Hot News and Announcements' section of the W6/PA0ZN web site has interesting information about the Leonids shower, along with several links. The web address for the W6/PA0ZN site is:

Bob, WB4APR, reports the Leonids should be an excellent opportunity to experiment with meteor scatter using very brief grid square packets. Bob reports during the Persieds shower in 1995, APRS stations recorded over 18 DX packets on paths between 600 to 1200 miles. Bob says station requirements include "a beam and power," and suggests that participating stations operate on 145.79 MHz, the known APRS frequency. Contact WB4APR for more information on APRS at the following e-mail address:

Additional information about the Leonid meteor shower is available at any of the following sites:

Semi-operational, currently in "sleep" mode.

W4SM tells ANS that he has, using ranging software (and hardware) developed by James Miller, G3RUH, recently made ranging measurements on AO-10 for the last week and have fed these measurements into an algorithm which generates modified Keplerian elements from a "seed" set of elements.

The Keplerian elements generated appear to be accurate within 16-25 km. More ranging measurements are being obtained from different Phase 3 command stations, and W4SM will update the AO-10 measurements as that data becomes available.

W4SM also reports that AO-10 continues to function well, with the exception of the usual QSB which is better or worse at different portions of the orbit. Strong signals have been observed, even out at apogee.

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM

AO-27 TEPR States are currently:
4 = 36 = 18 Minutes
5 = 72 = 36 Minutes

This means AO-27's transmitter turns on 18 minutes after entering the Sun and stays on for 18 minutes. AO-27's transmitter is turned off at all other times during the orbit. N4USI reminds stations that this happens on every orbit, approximately 14.2 times a day. The current TEPR settings will cause the satellite to be on during the daytime at northern latitudes.

Mike, N1JEZ, reports working 6Y5MV on AO-27 for satellite DX country number 103.

The present JA mode of operation will continue to investigate the frequency of bit errors in the on-board-computer. Reports from Amateurs on the value of channel 2A are appreciated. The position of 2A is the fifth item after 'HI HI' in CW telemetry. The normal value is '00'. Reports should be sent to

FO-29 is still in 'full sun illumination', this should end in December.

The on-board-computer (OBC) did accept commands from ground control before full illumination began. The FO-29 Command Team says digital (JD) mode operation may be available in December. Digi-talker operation is also being planned. The next announcement is expected November 20th.

John, K2JF, reports strong signals from FO-29 during orbit 11016. K2JF would like to see more activity during nightly US passes. Mike, KF4FD, has also been active on the satellite.
