Phase 3D Launch Update

AMSAT-DL Executive Vice President Peter Guelzow, DB2OS, has informed AMSAT News Service that the Phase 3D satellite is now "ready to fly" as it has passed all pre-launch inspection, testing and preparation.

Phase 3D is now scheduled for launch on Tuesday, November 14, 2000 from the European Spaceport in Kourou, French Guiana. This launch information comes from the Arianespace web site. The site now features the mid-November revised launch date for Ariane 5 Flight 135, on which Phase 3D will fly. The launch was delayed from a tentative October 31 window.

The 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/

Most of the recent photographs show the fueling process including both hydrazine and ammonia. According to launch team member Chuck Green, N0ADI, (who also helped fuel P3D) "ammonia sounds like something you can purchase at the local store for cleaning, but at 100% concentration it deserves the same precautions that rocket fuels are given." Chuck reports this was the first time ammonia has ever been used as a fuel in Kourou and only the second time worldwide, "so the process received a great deal of attention."

Following the successful fueling operation, installation of the solar panels was completed. Chuck told ANS that panel installation "was a little more difficult because at this point the satellite was already installed in the SBS."

N0ADI reported that combined operations then started with the first step of setting the satellite and SBS into the CCU transport container. "The next operation completed was to move the satellite from S3A, where we prepared and fueled it, to the Final Assembly Building where it will be placed on the rocket," said Chuck. Movement was conducted at night to avoid the daytime heat and involved a convoy of safety vehicles and a truck pulling the CCU container with P3D safely inside.

P3D spent the night in the Final Assembly Building before being opened, allowing the airlock in the building to be thermally stabilized. P3D was then moved and carefully lowered into place between two microsats already installed for launch.

With the satellite no longer in the S3A building, the AMSAT launch team vacated the office space in the S3 complex and moved to the block house overlooking the launch control room. Here they have a remote link where they can monitor the telemetry from the satellite, issue commands as needed and control the charging of the batteries.

Stay tuned to ANS for additional bulletins from AMSAT, the official source for information on the Phase 3D launch.

Discovery ISS Mission About to End

Space shuttle Discovery is scheduled to shoot up Florida's east coast on its way to ending the shuttle program's 100th mission. A landing at Kennedy Space Center is planned.

The landing was originally scheduled for Sunday afternoon but was postponed until Monday because of unfavorable weather in the Florida area.

The week long mission has been followed by amateur radio enthusiasts worldwide, in preparation for the first permanent crew and the start of ham radio operation from the station.

As reported by ANS, ARISS initial ham station gear was delivered last month to the station and has been stowed until the Expedition 1 crew arrives. That crew, U.S. astronaut Bill Shepherd, KD5GSL, Russian Cosmonaut Sergei Krikalev, U5MIR, and Cosmonaut Yuri Gidzenko, are scheduled for a four-month stay following launch from the Baikonur Cosmodrome in Kazakhstan. That launch has now been set for October 31st.

AMSAT Symposium Draws Near

The 18th Space Symposium and AMSAT-NA Annual Meeting in Portland, Maine is less then a week away and according to Symposium Chairman George Caswell Sr., W1ME, a full schedule of activities is planned.

The 2000 Symposium will include once top-secret details about intelligence gathering methods used during the early years of the Cold War. The Saturday banquet speaker will be Cargill Hall, chief historian of the National Reconnaissance Office. He will discuss (for the first time in public) overhead reconnaissance along with a history of CIA-NRO activities.

InstantTrack 1.50 will be released at the Symposium. To view some of the changes that have been made in this popular satellite tracking program, see http://www.amsat.org/amsat/instanttrack/

A Symposium special event station will be active during the event using the AMSAT Club Callsign W3ZM. Both satellite and HF operation is planned. AMSAT Area Coordinator Bruce Paige, KK5DO, tells ANS that antennas for the station will be mounted on the roof of the hotel hosting the event. "There will also be HT operation from the parking lot on several of the FM repeater birds," said KK5DO.

Look for W3ZM on the air from October 26-29th. A special certificate and QSL card will be available to those that work the station.

OSCAR SKN 2001

ANS reminds all satellite operators that it's not too early to start planning for OSCAR SKN operation. All amateur radio operators worldwide are cordially invited to participate in AMSAT-NA's 29th annual Straight Key Night on OSCAR, to be held from 0000 to 2400 UTC on January 1, 2001.

According to event organizer Ray Soifer, W2RS, the event is totally informal. "There are no rules, no scoring and no need to submit a log," said W2RS, "just have fun operating Morse code with a straight hand key via any amateur radio satellite." Even OSCAR Zero (the moon) can be used during SKN. Stations should call CQ SKN or answer such calls from other stations.

In keeping with the friendly tradition of this event, each SKN participant is encouraged to nominate someone he or she worked for 'Best Fist'. Those nominated will be listed in an ANS bulletin and in the AMSAT Journal.

Best Fist nominations should be sent to W2RS using the following:

e-mail - w2rs@amsat.org
packet radio - W2RS@WA2SNA.NJ.USA.NA

Nominations can also be sent via surface mail using the W2RS callbook address.

International Space Station/ARISS

Uplink to be released
Downlink to be released
ARISS initial station launched September 2000 aboard shuttle Atlantis
Status: Non-operational

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.

More information about the project can be found on the ARISS web site at http://ariss.gsfc.nasa.gov

Uplink 145.850 MHz FM
Downlink 436.795 MHz FM
Launched September 26, 1993 by an Ariane launcher from Kourou, French Guiana
Operational

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

JAS-1b FO-20

Uplink 145.900 to 146.000 MHz CW/LSB
Downlink 435.800 to 435.900 MHz CW/USB
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.

Beacon 2401.500 MHz
Launched March 1, 1994 by a Delta-Thor rocket from Vandenberg Air Force Base in California
Operational.

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.

The following satellites are in orbit but are non-operational at this time:

KITSAT KO-23

Uplink 145.850, 145.900 MHz FM
Downlink 435.175 MHz FM, 9600 Baud FSK
Launched August 10, 1992 by an Ariane launcher from Kourou, French Guiana
Status: Non-operational.

Jim, AA7KC, reports that KO-23's downlink transmitter has been operational on several recent passes, but has since returned to the transmitter off state. The downlink transmitter is operating at unpredictable intervals.

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.
