AMSAT-DL Executive Vice President Peter Guelzow, DB2OS, tells AMSAT News Service that the Phase 3D satellite continues in a "ready to fly" status hold at the European Spaceport in Kourou, French Guiana.
The Phase 3D launch window will open on Tuesday, November 14, 2000. The revised launch date for Ariane 5 Flight 135 -- on which Phase 3D will fly -- was changed from the tentative October 31st initial launch window. Phase 3D is scheduled to be launched with three other satellites - including the large PAS-1R communications satellite and the much smaller STRV-1C and 1D satellites.
A view of the entire payload can be found at http://www.arianespace.com/news_missionupdate.html
Information about the STRV-1C and 1D satellites can be found at http://www.dera.gov.uk/html/news/strv_overview.htm
After launch, P3D will be in a transfer orbit used for geosynchronous satellites. Through firing the onboard 400N motor, P3D's perigee height will be increased to 4,000 km. Then, through another firing at perigee, P3D's apogee will be increased to 47,000 km. At apogee, the motor will burn once again, placing the satellite in an inclination of about 60 degrees. P3D's designers are currently planning for a northern hemisphere apogee drift after some 2-years in orbit. At that point, the onboard ATOS motor will be used, first to change the P3D orbit to a final inclination of about 63 degrees, and, after that time, the motor can be used for small orbit changes.
The AMSAT launch team reports the 'Callsign to Fly' plaque was mounted onto a side panel before the panel was installed on P3D. A photograph of the plaque before installation is available at http://www.uk.amsat.org/images/onp3d.jpg
The AMSAT launch team Internet web site has been popular with satellite operators around the world. The site features photographs showing the Phase 3D launch preparation process. See http://www.amsat-dl.org/launch/
Stay tuned to ANS for additional bulletins from AMSAT, the official source for information on the Phase 3D launch.

Flight controllers in Houston and Moscow are preparing the International Space Station to come to life next week with the arrival of its first inhabitants. The Expedition-1 crew is set to blast off aboard a Russian Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, bound for ISS. The crew should arrive aboard the station shortly thereafter and then begin a four-month stay as the first permanent occupancy of the international complex.
The launch from Baikonur is set for October 31st. NASA television plans extensive coverage of the launch.
Amateur radio satellite operators worldwide have been following ISS developments and are especially excited about this flight as ham operation is expected to debut soon after the Expedition-1 crew arrives aboard the International Space Station. The crew includes expedition commander/U.S. astronaut Bill Shepherd, KD5GSL, Soyuz vehicle commander/Russian cosmonaut Yuri Gidzenko, and flight engineer/cosmonaut Sergei Krikalev, U5MIR.
The flight to the ISS will take approximately two days following the launch. The crew has expressed a high level of interest in beginning amateur radio operations early in their mission but it may be several weeks before they can set up the ham station and begin operations.
Initial operations will take place only in the 2-meter band. The tentative frequencies are:
Worldwide downlink for voice and packet: 145.800 MHz
Worldwide packet uplink: 145.990 MHz
Region 1 voice uplink: 145.200 MHz
Region 2/3 voice uplink: 144.490 MHz
Two U.S. call signs have recently been issued for amateur radio operations with ISS. The FCC granted vanity call signs NA1SS and NN1SS to the International Space Station Amateur Radio Club in mid-October. The NA1SS call sign will be used aboard ISS, and NN1SS will be used for ground-based transmissions from the Goddard Space Flight Center. As ANS has reported, Russian call sign RZ3DZR along with the German call sign DL0ISS have both previously been issued for use aboard the station. The crew may use their own call signs (KD5GSL, U5MIR) or they may use one of the ISS calls.

Several news agencies are reporting the Mir space station will be de-orbited early next year. The previously announced hope that private funds may save the nearly 15-year-old Mir are apparently not coming to fruition.
Earlier this year, the station had won a new lease on life when a private company signed a lease agreement and provided funds to keep the station aloft. Russian officials have now left no doubt that the decision to de-orbit Mir is indeed final and are now preparing the details of the operation to discard the venerable station.
Mir has been quickly losing altitude since its latest crew left in June. The current thinking is that a Progress supply ship with a larger amount of fuel will be launched to Mir to give it the final impulse and start the splash down.
Mir was launched on February 18, 1986. Currently, there is no human habitation aboard the station and the onboard amateur radio equipment has been turned off. Mir is currently on 'autopilot'.
ANS has carried the following report for several months:

ARISS initial station launched September 2000 aboard shuttle Atlantis
Status: Expected operation to begin in mid-November
The ARISS initial station gear is now temporarily stowed aboard the Functional Cargo Block module of ISS. The initial station will use an existing antenna that will be adapted to support 2-meter FM voice and packet. The ARISS equipment will get a more-permanent home aboard the Service Module in 2001, along with VHF and UHF antennas. Plans call for amateur TV, both slow scan and fast scan ATV, a digipeater and relay stations.
Planning for the deployment and use of the ham system aboard ISS has been an international effort coordinated by NASA's Goddard Space Flight Center. The effort began in 1996 with the formation of the Amateur Radio International Space Station organization. ARISS is made up of delegates from major national amateur radio organizations, including AMSAT.
Two U.S. call signs have recently been issued for amateur radio operations with ISS. The FCC granted vanity call signs NA1SS and NN1SS to the International Space Station Amateur Radio Club in mid-October. The NA1SS call sign will be used aboard ISS, and NN1SS will be used for ground-based transmissions from the Goddard Space Flight Center. As ANS has reported, Russian call sign RZ3DZR along with the German call sign DL0ISS have both previously been issued for use aboard the station. The crew may use their own call signs (KD5GSL, U5MIR) or they may use one of the ISS calls.

Periodically, AO-27's analog repeater will be turned off for a few days at a time to enable ground controllers to gather Whole Orbital Data (WOD), to verify the health of the satellite.
An AO-27 question-and-answer page is available on the AMSAT-NA web site: http://www.amsat.org/amsat/intro/ao27faq.html.
AO-27 uses a method called Timed Eclipse Power Regulation (TEPR) to regulate the on-board batteries. In simple terms, TEPR times how long the satellite has been in an eclipse (or in the sun) and decides what subsystems to turn on or off. The current TEPR settings are:
TEPR 4: 36
TEPR 5: 72
The AO-27 pages on the AMSAT-NA web site include an explanation of TEPR AO-27 operations at http://www.amsat.org/amsat/sats/n7hpr/ao27.html

Launched February 7, 1990 by an H1 launcher from the Tanegashima Space Center in
Japan
Operational.
FO-20 is in mode JA continuously.
Several satellite operators have reported problems with FO-20's transponder. Mike, N1JEZ, told ANS that he believes the loss of signal is a combination of two factors. First, battery age and an increase in FM traffic due to operators unaware of the band plan. Mike reports he routinely hears FM signals on the transponder.
Tak, JA2PKI, reported the FO-20 control station operators now believe that the UVC (Under Voltage Controller) now is regulating the transponder. The UVC monitors battery voltage and tries to protect the batteries from over discharge. Tak notes that FO-20, launched in 1990, is now over 10 years old.
[ANS thanks Kazu Sakamoto, JJ1WTK for the FO-20 status reports]
The JARL FO-29 command station has announced the following operation schedule of FO-29:
| Oct 7 - Nov 5 | Digi-talker (except mode JA every Wednesday) |
Mike, KF4FDJ, has put together a very informative document on FO-29, addressing analog, digital and digi-talker modes. To obtain a copy e-mail Mike at kf4fdj@amsat.org
Mineo, JE9PEL, has updated his FO-29 satellite telemetry analysis program. The software will automatically analyze all digital telemetry from the satellite such as current, voltage and temperature. The JE9PEL FO-29/software update is available at http://www.ne.jp/asahi/hamradio/je9pel/

Downlink 435.175 MHz FM, 9600 Baud FSK
Launched August 10, 1992 by an Ariane launcher from Kourou, French Guiana
Status: Intermittent operation with the downlink transmitter operating at unpredictable intervals
Jim, AA7KC, reports that KO-23's downlink transmitter has been operational (as of 10/27/00). Duration of this status is unpredictable.
KyungHee Kim, HL0ENJ, reports (from the KO-23 control team) that part of the problem with non-operation has been the power budget aboard the satellite. HL0ENJ also reports that KO-23 is currently in a full sunlight period that should last through the end of October. The control team will attempt to operate the satellite during this period along with an attempt to control the attitude system. "We are not sure when the bird might be turned off again due to insufficient power. The capability of the onboard power system has been less and less," said Kim.

OSCAR-11 celebrated its sixteenth birthday on March 1, 2000.
During the period 16-September to 17-October excellent signals have been received from the 145 MHz beacon. The satellite is currently experiencing very good solar conditions that should continue through the end of the year.
Ground control operations recently reset the magnetorquer counters and the spin period has now started to slowly return to a nominal value.
The battery voltage observed during daylight passes has continued to increase. The average value observed was 14.0, with a range of 13.9 to 14.1 volts. The internal temperatures have increased recently. They are now 5.8C and 4.2C for battery and telemetry electronics respectively. This rise in temperature is expected to continue as solar eclipse times become shorter.
The operating schedule is unchanged.
