ISS Crews Named

NASA recently named the first team members to live and work aboard the International Space Station, and four crew members already hold ham tickets. In addition, several of the crew members are studying for their licenses.

The first crew will consist of American astronaut William M. Shepherd, as the expedition commander. Shepherd is currently studying for his ticket. He'll be accompanied by Russian cosmonauts Yuri Gidzenko and Sergei Krikalev, U5MIR. The crew is training for an early 1999 launch and a planned five-month mission on the ISS.

The second crew, headed by Russian cosmonaut Yuri Usachev, R3MIR, will include US astronauts Susan Helms, KC7NHZ, and James S. Voss, who's indicated an interest in getting his ham ticket.

No licensed hams are among the third crew, which will be headed by astronaut Kenneth Bowersox and will include Russian crewmates Vladimir Dezhurov and Mikahil Turin. Bowersox also has said he'd like to get his ham license.

Russian cosmonaut Yuri Onufrienko will head the fourth crew. US astronauts Carl Walz, KC5TIE, and Daniel Bursch will accompany him.

AMSAT-NA's VP of Manned Space, Frank Bauer, KA3HDO, reports that the international team developing the ISS ham radio station is now working hard to incorporate a transportable ham station for ISS, and deliver this equipment to the Johnson Space Center in Houston, Texas for flight certification in June, 1998. Initially, ISS crews will inhabit the service module, which will include a ham radio antenna, with ham gear scheduled to be delivered aboard the STS-96 shuttle flight. Microsat/repeater payloads are tentatively scheduled to arrive in early 2002, expanding ham radio capability aboard the station.

Stay tuned to ANS for more information on ham radio's planned presence on ISS as it develops.

Phase 3D Update

Phase 3D Project Leader Karl Meinzer, DJ4ZC, recently visited the Phase 3D Integration Lab in Orlando for a top-to-bottom review of Phase 3D's status. The Phase 3D satellite was to have been aboard the Ariane 502 flight October 30, but ESA's revision of launch environments, and the consequent structural modifications to the satellite's spaceframe made it impossible for Phase 3D to meet the 502 flight schedule.

According to AMSAT-NA President Bill Tynan, W3XO, the structural work is now essentially complete and the crew at the Orlando lab are beginning to re-install electronic modules and other equipment which had to be removed so that the structural work could proceed. Following this tests will be conducted to confirm satisfactory interoperability of all of the satellite's various sub-systems and then environmental testing will take place.

Tynan further stated that he doesn't expect any new information concerning a launch date and vehicle for Phase 3D until well after European space authorities determine the root cause of the early engine shutdown that took place on the recent Ariane 502 flight.

Keith Baker, KB1SF, AMSAT-NA's Executive Vice President noted that according to the original schedule, the next Ariane 5 vehicle (503) is due to lift off in May, 1998, for the final qualification flight of the Ariane 5 program. The first Ariane 5 commercial launch (L504) is currently planned for the second half of 1998.

DOVE QSL Update

Jim White, WD0E, reports strong requests for Dove (DO-17) QSL cards. To receive a DOVE QSL, receiving stations need to send a request indicating the date, time and frequency the satellite was received. Jim reports that it is not necessary to send a breakdown of the satellite telemetry or a printout of received data. Include a self addressed stamped envelope (SASE) or an addressed envelope with an International Reply Coupon (IRC) with your request. Reception reports should be sent to:

  Dianne White N0IZO
  45777 Rampart Road
  Parker, Colorado 80138-4316
  USA

Jim also notes that for those stations that would like to decode the DO-17 data, several programs are available to decode the telemetry from DOVE. Some shareware decoders can be found on Compuserve and America On Line. Also the decoder TLMDCII, which includes an extensive .DOC file of information about Microsat telemetry (including DOVE), is available from AMSAT-NA.

KB5YSQ to Command Shuttle

NASA has announced that astronaut Charles Precourt will command the final space shuttle/Mir docking mission scheduled for May of 1998. Precourt holds the amateur call KB5YSQ.

The May mission, designated as STS-91, will be aboard the shuttle Discovery. Precourt has visited the Russian space station twice before. NASA also announced that the flight crew will include Wendy Lawrence, KC5KII.

The May mission will retrieve US astronaut Andy Thomas, KD5CHF, from the Mir station. Thomas is scheduled to travel to Mir in January.

Mir

(Uplink 437.850 MHz FM, Downlink 145.800 MHz FM)

Dave Wolf has stated that powering up the radio is "on his list" and it is hoped that Mir will be back on the air soon.

As part of ongoing frequency experiments to improve amateur radio operations on board Mir, and to better understand how these frequencies will be effective on the International Space Station, Mir will begin a 2-phase frequency experiment beginning December 1, 1997 and ending on May 31, 1997.

For phase 1, a 70cm/2m crosslink experiment will operate for a 3 month period from December 1, 1997 up to March 1, 1998. On December 1, 1997 the Mir operating frequencies will change to:

Uplink: 437.850 MHz Downlink: 145.800 MHz

Phase 2 of this experiment will use a 2 meter-only set of uplink and downlink frequencies. This phase of the experiment will begin on March 1, 1998 and will also be of 3 months duration.

SAFEX, Mir 70cm Repeater

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

The SAFEX activity very intermittent.

KO-23

(Uplink 145.85, 145.9 MHz FM, Downlink 435.175 MHz FM, 9600 Baud FSK.)

KO-23 downlink efficiency is near zero percent.

Stacey Mills, W4SM, has estimated the keps show that KO-23 will not experience an eclipses again until December 12th. During the orbits of that day, eclipses rapidly increase in duration from 2 to 11 minutes. Eclipse length will then continue to increase, peaking at 35 minutes per orbit in the December 28th thru January 4th time period. Eclipse length will then begin slowly decreasing again. KO-23's download efficiency has dropped dramatically due to the increasing heat and its affects on the signal deviation.

AO-10

(Uplink 435.030-435.18 MHz CW/LSB, Downlink 145.975-145.825 MHz CW/USB)

Operational.

Stacey Mills, W4SM, would appreciate any perigee observations of AO-10's beacon or transponder during the next several weeks until conditions begin to improve. If his orientation figures are correct, AO-10 should be down to a solar angle of -84 degs with only 11% illumination. Send reports to w4sm@amsat.org.

OSCAR-11

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

Operating normally.

During the period of October 14th through November 16th this satellite has continued to provide good signals on its 145.826 MHz beacon.

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/.

UO-22

(Uplink 145.9 or 145.975 MHz FM; Downlink 435.120 MHz FM 9600 Baud FSK.)

UO-22 is operating normally.

Chris Jackson, G7UPN / ZL2TPO, has reloaded the Store and Forward communications task on the UO-22 On-Board Computer. This task includes incremental checksums which should make uploading slightly faster. In the old task, once an upload was complete, the spacecraft had to perform the checksum on the complete file. Depending on the file length, this could take quite a long time. With the new task, the checksum is computed on the fly - while the data is actually being uploaded. Thus there is no need to recompute it at the end of the transfer and this checksum delay is then removed.

However, all files that were started before Chris Jackson, G7UPN/ZL2TPO, loaded the task around 1000 UTC on the 19th will receive a corrupt body checksum error when the upload is completed. If the file is uploaded again, it should be accepted. If trying to upload a large file that was started before the above time, then start again.

If anyone gets persistent body checksum errors while uploading files to UO-22 would they please let Chris Jackson know as soon as possible
