ISS Construction Is Underway!

ANS is pleased to report that construction of the International Space Station is underway as five Americans and one Russian successfully lifted off aboard the Space Shuttle Endeavour from the Kennedy Space Center with the first American-built component of the station -- a connecting module named Unity -- in the shuttle cargo bay. According to NASA, the shuttle's climb to orbit was flawless. Following the smooth launch, Commander Bob Cabana, Pilot Rick Sturckow and Mission Specialists Nancy Currie, Jerry Ross, Jim Newman and Sergei Krikalev began preparing the orbiter for 12 days of operations to begin ISS construction.

The STS-88 launch will begin the largest cooperative space construction project in human history as Endeavour linked with the U.S.-funded and Russian-built Zarya control module. Zarya was recently launched from the Baikanour Cosmodrome in Kazakhstan, and has been circling the Earth since November 20th as flight controllers initially checked out the spacecraft. All systems aboard Zarya, which will provide the initial control and command capabilities for the space station, continue to function well with the minor exception of one of six battery charging systems. NASA tells ANS that Endeavour is carrying replacement parts for the system in the event they are needed.

AMSAT Area Coordinator Pat Kilroy, WD8LAQ, reported spotting Endeavour right after launch -- from his Bowie, Maryland front yard. "The light from the shuttle main engines appeared like a reddish-white star," said WD8LAQ, adding "the 'star' then dimmed and disappeared right at the time NASA announced main engine cut off (MECO)."

With the Russian-built Zarya Control Module orbiting about 16,000 nautical miles in front of Endeavour, Mission Specialist Nancy Currie first checked out the 50-foot-long robot arm that she would use to grapple the Unity connecting module. Following the successful test, Currie gently mated the 12.8-ton Unity connecting module to Endeavour's docking system, completing the first task in assembling the new International Space Station. Following this success, Endeavour's astronauts continued the assembly of the ISS late Sunday, mating the Russian-built Zarya control module with the U.S.-built Unity connecting module in the shuttle's cargo bay. This very important step followed a flawless rendezvous and grapple of Zarya.

The two ISS elements, Zarya and Unity, are now connected together -- creating the foundation for the new station. More than 100 elements will be added over the next five years, requiring a total of 45 assembly flights using the shuttle and two types of Russian launchers.

The two connected modules have a solar array span of about 78 feet and a combined mass of approximately 80,000 pounds. Several spacewalks will now follow the mating of Unity with Zarya, for initial crew entry into the new station and to connect power and data cables between the modules.

Amateur Radio aboard ISS begins with final flight qualification of the ARISS interim station expected to be completed this month. This station will allow the crew to operate on voice, packet and digital voice beacons at the beginning of station habitation in mid-1999.

Endeavour is orbiting the Earth at an altitude of about 240 statute miles.

The following is a two-line orbital element set for STS-88:

SimSat Program Receives NASA Award

AMSAT Area Coordinator Pat Kilroy, WD8LAQ, tells ANS that the Simulated Satellite (SimSat) Project recently won a NASA Goddard Space Flight Center Director's Discretionary Fund (DDF) award. The Simulated Satellite project is an educational outreach program at NASA-GSFC.

According to Pat, "the award is good news for students and Amateur Radio alike." WD8LAQ reports the award includes funding (for the '99 fiscal year) a university student engineer -- working full time during the upcoming summer months helping further develop SimSat hardware -- and at least one (and possibly more) teachers -- helping to further develop the educational side of the SimSat program.

Pat recalls the original concept of SimSat was born during a local AMSAT-DC meeting. WD8LAQ and others were looking for a local project, admiring the balloon success of Andy MacAllister, W5ACM, Bill Brown, WB8ELK and Chuck Crist, WB9IHS. "The dream, " Pat said, "was wanting to do something bigger and better for student education -- all in a spirit of wholesome competition." The result was the SimSat program was born, based on the idea that designing, building and then flying, operating and recovering payloads by balloon is a great stepping stone for helping youngsters learn about Oscar satellites.

The NASA Director's Discretionary Fund award means there is ample opportunity for Amateur Radio operators to participate in ham radio balloon flights and to share the fun with students.

WD8LAQ tells AMSAT News Service that he will update ANS on the exciting developments that the DDF award will bring to the SimSat program in the future.

RS-18/Sputnik 41

Downlink 145.812 MHz FM

Russian cosmonauts successfully launched RS-18/Sputnik 41 on November 10, 1998, during a spacewalk from the Mir space station. The spacecraft is just under 8 inches in diameter, weighs almost 9 pounds and carries a 200-mW transmitter. RS-18 has no solar cells and its expected operational lifetime is approximately 30 days.

Recent RS-18 reception reports have been received from SP6QPK. The satellite was even copied by ANS editor NN0DJ, who was mobile at the time!

Hank, N1LTV, tells ANS he has put together a 'Sputnik-41 Telemetry Assistant' software program that may be of help to those monitoring RS-18. The software tacks the internal temperature of the spacecraft, recording the report in Fahrenheit and/or Celsius rounded to a tenth of a degree. The free program is available for downloading at:

AO-10

Uplink 435.030 to 435.180 MHz CW/LSB
Downlink 145.975 to 145.825 MHz CW/USB
Beacon 145.810 MHz (unmodulated carrier)
Operational.

Nick, W0CA, recently reactivated his AO-10 station and reports a nice roundtable QSO with VE5FN, KF4FDJ and KD2JF. He then worked Xaever, F6FXU. Jeff, KO6RD, reports AO-10 has been working extremely well with 17 recent contacts (15 from Europe with some signals reaching S-9 or better). Jerry, K5OE, has been active as has Frank, PE1KNL, John, K6YK, Selva, 9V1UV, and Dejan, 9A4ZD.

AO-10 continues to function well with the exception of the periodic deep QSB, which can be partially eliminated by switching antenna polarization. Strong signals have been heard even at apogee. Also note that AO-10's apogee is approaching its most northern point (ArgP = 270). This gives the satellite track on a rectangular (Mercator) map projection a distinctly symmetrical pattern. The apogee will begin a slow migration southward.

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.

Note: This element set may have to be entered by hand or cut and pasted line by line into a tracking program, rather than automatically extracted. They are not in the complete AMSAT format, orbit# (Epoch rev), Element set#, and Checksum are not included.

AO-27

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM
Operational.

The TEPR settings of AO-27 were recently reset by Chuck, KM4NZ. The new settings now reflect the Earth's position during the northern fall/winter season, and should provide more satellite 'on' time for AO-27 during each pass.

Jeff, KF4KGQ, tells ANS he was "more excited than the day I got my drivers license" after making a contact on AO-27 using his handheld. Jeff reports that much of his AO-27 information came from ANS and the AMSAT-BB.

Downlink 435.910 MHz FM 9600 baud BPSK
Not operational, the satellite is in JA (voice) mode.

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. Telemetry has been nominal.

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.

TMSAT-1 TO-31

Downlink 436.923 MHz

TMSAT-1 is now open for general access by Amateur Radio operators worldwide. TMSAT commissioning has been completed and shows that most of the spacecraft systems are operating correctly. Normal access will allow operators to use the store and forward communications on the spacecraft and also download the high-resolution multispectral images.

It is hoped Amateur Radio operators will take advantage of the high-resolution multispectral images available from TO-31 and keep other traffic to a minimum. Due to current limitations with on-board memory, images will only be available on the satellite for a few days after they are taken. Software to display the thumbnail images from the WAC (Wide Angle Camera) will be released shortly.

Testing will continue and access may be limited to command stations only. If at any time the BBS is in a 'SHUT' mode as displayed in WiSP (or any of the digital programs), do not attempt to access the satellite as it may delay any command string that is underway.

Francisco, CT1EAT, reports he has successfully connected with TO-31, receiving a S-7 (peaking S-9) signal from the satellite. Other reports of successful TO-31 operation have been received from Rick, KB0VBZ, Gilbert, N3RZN, and John, G0ORX.

A set of TO-31 orbital elements has been received from G7UPN:
