Thank You from ANS

Later this week in the United States, many citizens, some of them Amateur Radio satellite operators, will celebrate a national holiday called Thanksgiving. For our international audience, Thanksgiving is a time when we give 'thanks' for the important things in our lives, such as family and friends.

Our ANS editor would also like to reflect on the many satellite operators and organizations that have become close friends with ANS through the weekly ANS bulletin activities. Many, many stations worldwide continue to send satellite news and reports that in turn become the main body of information and data presented each week in ANS. Without the help of such dedicated individuals and national/international organizations, ANS would simply not exist.

From ANS, happy Thanksgiving and thank you one and all!

ISS Underway

The first module for the new International Space Station was successfully launched on the morning of November 20, 1998, aboard a Russian Proton rocket from the Baikonur Cosmodrome in Kazakhstan. The successful liftoff took place under overcast skies and strong winds.

The Zarya module -- which reached orbit less than 10 minutes after launch -- will serve as a space propulsion engine and power station during the early stages of the ISS project, providing propulsion, power and space-to-ground communications. Later modules will take over these functions and Zarya will eventually serve as a storage facility, holding fuel and other needed supplies.

The module does not currently have any life-support systems such as oxygen, plumbing or any of the other essentials for living in space. Astronauts will be able to move around inside (without spacesuits) only after the living quarters are attached to one of the three docking ports. Using the published construction schedule, the living quarters are to be installed in July 1999.

Zarya (Russian for 'daybreak') is a cylinder-shaped module just over 41 feet long and almost 14 feet wide with solar panels extending some 35 feet on both sides of the exterior. The module weighs 42,600 pounds and is actually based on a modified and updated design of the earlier Soviet Salyut space stations.

The International Space Station, scheduled to be completed in 2004, will be the largest complex structure in space, sprawling across an area the size of a football field. ISS construction activities will start with the STS-88 shuttle launch from the Kennedy Space Center on December 3rd.

Amateur Radio aboard ISS begins with final flight qualification of the ARISS interim station expected to be completed in December. This station will allow the crew to operate on voice, packet and digital voice beacons at the beginning of station habitation.

Ken, N2WWD, has posted orbital data for the Zarya module and the upcoming STS-88 mission on the AMSAT Shuttle Orbital Information web page at the following URL:

Leonids Aftermath

Although successfully viewed across many parts of the globe, all reports are pointing to the Leonid meteor shower peaking ahead of schedule, with the highest rates apparently about 15 hours earlier than expected. European observers may have had the best show as dazzling fireballs came every few seconds -- sometimes several at the same time. Clear skies in Ichon, South Korea gave crowds in that location very good seats for the spectacle.

Based on dozens of reports from observers and satellite operators throughout the United States, meteor watchers under clear skies were not disappointed on the nights of November 16-17, but rates were markedly lower then had been hoped for.

No damage to any Earth-orbiting satellites has been reported to ANS.

Late night operation and long early morning hours was a small sacrifice to the many VHF and UHF enthusiasts who got the thrill of a lifetime working meteor scatter during the event. Larry, NW7N, told ANS his group was treated to "excellent visual conditions in southern Arizona," adding, "we saw between 1000 to 1500 meteors during the first night". According to NW7N, the meteors came in all sizes, many emitting a green glow and leaving visible ionization trails.

"For nearly all radio operators, it was spectacular," said Shelby, W8WN, "this was the year of the fireballs." W8WN and others also seem to agree that this was also the year for long-distance contacts, possibly a few record-setting ones. "My biggest thrill was working Vermont on 2-meters, which is over 1400 miles away," said Larry, N0LL, who lives in northern Kansas. He said he encountered one "burn" -- or trail -- that lasted nine minutes, during which he was able to work 11 different stations.

Several e-mail reflectors were busy with Leonid reports and information, including the AMSAT bulletin board. W4WHN, PA2CHR, KO0U, WZ1V, VE6BPR, K5NRK, WB4APR, GW6KZZ, N2NRD, K7RR, N0JK, N1LTV, PE1OGF, WA9JML, WB8ELK, N1JEZ and DF9CY all posted reports or information about Leonid operation for others to see and read.

The Leonids balloon launched from Marshall Space Flight Center in Alabama was located a day after landing in Georgia. Real Video from the flight camera is available at the following URL:

Kazu, JJ1WTK, tells ANS that the FO-29 Command Team has released the following announcement concerning FO-29 status:

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 lab@jarl.or.jp.

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.

OSCAR-11

Downlink 145.825 MHz FM, 1200 baud PSK
Beacon 2401.500 MHz
Operational.

Clive, G3CWV, reports an uneventful month for OSCAR-11. During the period of 14-October to 15-November, reasonable signals have been received from the 145.826 MHz beacon.

Telemetry has been nominal.

Battery voltage is nominally 13.9 VDC. The internal temperatures have been almost constant and are now 10.2 and 8.0 degrees Celsius for battery and telemetry electronics respectively. These values appear to have reached a maximum value and are now expected to fall slowly.

The present length of solar eclipses appears optimum for the satellite, maintaining an adequate power budget and not allowing internal temperatures to rise to excessive levels.

Magnetorquer spin correction counters have been of interest. Normally, the negative spin counter increments are at roughly half the rate of the Z-axis counter. Over the last two months there have been very few spin counter increments, although the spin period is nominal.

The ASCII bulletin is currently a static message, detailing modes and frequencies of the current amateur radio satellites.

The mode-S beacon is on, transmitting an unmodulated carrier, however telemetry indicates that it has partially failed, delivering half power. This beacon is a useful test source for those testing mode-S converters prior to the launch of P3D. The 435.025 MHz beacon is normally off.

Two new WOD software packages have recently added to the Oscar 11 web site. The first package enables various WOD channels to be compared with the solar eclipse status of the satellite. The second package compares measured and calculated magnetic fields encountered by Oscar 11. Both packages are of an advanced nature, users will need experience using the other WOD packages on the web site and a spreadsheet program.

Telemetry is reported as being received on 435.822 MHz at 1200 baud PSK. No additional information is available at this time.

TMSAT-1 TO-31

Downlink 436.923 MHz

The TMSAT-1 micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998.

TMSAT commissioning has been completed and shows that most of the spacecraft systems are operating correctly. A problem was identified with the downlink transmitter and this is currently limiting the use of the downlink to periods when the satellite is over Europe and Thailand. 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.
