AMSAT-NA Strategic Planning Team Formed

Under the guidance of Bill Burden, WB1BRE, AMSAT-NA Vice President for Strategic Planning, AMSAT's strategic planning process is about to re-commence.

The initial idea is to review the current AMSAT-NA mandate and then present those findings to the Board of Directors, either confirming the current AMSAT-NA mandate -- or to make appropriate changes.

This action will require a considerable amount of work by those involved, but according to AMSAT-NA Executive Vice President Robin Haighton, VE3FRH, "both AMSAT-NA President Keith Baker and I consider this to be an essential action that must be completed before the next annual AMSAT-NA meeting in San Diego." At that time, added VE3FRH, "any proposed changes may be placed in front of the general membership."

Team members were chosen from active members of AMSAT-NA, representative of the general membership and the geographical areas served by AMSAT-NA itself.

Current team members are:

Bill Burden WB1BRE
Keith Baker KB1SF
Russ Tillman K5NRK
Ken Ernandes N2WWD
Bdale Garbee N3EUA
Dan James NN0DJ
Steve Bible N7HPR
Robin Haighton VE3FRH

Stay tuned to ANS for further developments of the Strategic Planning Team.

Mir/APRS School Roundup

Bob Bruninga, WB4APR, tells ANS the annual ARRL School Club Roundup (SCR) event will take place from February 8-13, 1999, with the objective to get as many schools on the air as possible using all amateur bands all modes.

With that in mind, WB4APR notes that the Mir space station orbit during that week over North America makes this an ideal opportunity for students to participate in satellite communications as well.

As part of the ongoing APRS/Mir/School experiments, MIREX president Dr. Dave Larson has endorsed the maximum participation of all schools to use the Mir digipeater to exchange communications between schools during the weeklong event. APRS style operations can handle as many as 100 stations per pass, so any school with a 2-meter FM radio, simple antenna and a TNC should be successful. The frequency will be 145.985 MHz.

Bob reminds everyone the APRS/Mir portion of this event is not a contest, but an "opportunity for students and schools to learn about space communications." WB4APR encourages amateurs to contact a local school science teacher and schedule a time period during the event when you can help set up and/or operate a school club station.

The live APRS/Mir downlink is always visible on the Naval Academy/MIREX web page at the following URL:

The ARRL School Club Roundup contest is described in detail on page 92 of the January 1999 QST. For more information visit:

W1B Special Event Station

Mike Seguin, N1JEZ, has informed ANS that again this year, the W1B special event station will be active during the Vermont QSO Party. W1B is operated in commemoration of Wilson 'Snowflake' Bentley.

The station will be active on all high frequency bands and several active analog satellites, operating from grid square FN34. Operation will start at 13:00 UTC on Saturday, February 6th, and will end at 23:00 UTC the following day.

Mike tells ANS that a group of local AMSAT folks are planning W1B operation on the active analog satellites during this period. According to N1JEZ, operation is currently planned for FO-20, FO-29, AO-10, AO-27, RS-13 mode A and RS-15 mode A.

W1B will issue a colorful certificate for 2-way confirmation.

Mike notes during past operations, over 100 satellite contacts were made during the event. On HF, worked all states (WAS) was achieved in the first 6 hours of operation!

SUNSAT Launch Delayed

Proving that the satellite launch business is actually rocket science -- and frustrated by numerous weather-related delays -- the Boeing team that's attempting to launch a Delta II rocket carrying the Sunsat amateur satellite (and two other payloads) ran into a technical snag during the January 28th launch attempt.

Eric Lemmon, WB6FLY, reports that at 1044 UTC on Thursday, January 28th, the Delta II rocket experienced a main engine cutoff immediately after the engine start command was issued. The shutoff is sent automatically when an anomaly in the engine sequence is detected.

The cause is of the shutdown is currently under investigation. No damage occurred to the rocket or to the three satellites that comprise the payload.

Cliff Buttschardt, K7RR, tells ANS the NBC news bureau near the Vandenberg launch pad featured a nice discourse on the number of delays occurring with the Delta launch. The NBC report mentioned upper air winds as the primary cause of the launch delay, but other excuses including abnormal wind direction (in which debris might fall over a populated area and ship channel traffic offshore) were also offered. The NBC story also had a very nice description of the Oersted and Sunsat satellites.

No further information on the Delta launch is available at this time. Stay tuned to ANS as this story unfolds.

John, KD2JF, tells ANS that an effective 10 meter antenna for mode A work is the turnstile. KD2JF reports he has been using a turnstile located about 8 feet above ground, noting it "is the best mode A antenna I have used." John says the turnstile has "a very low receive noise level and hears very well over the top."

Garie, K8KFJ, reports Bruce, ZF2CM, has been active on RS-13. XE2YVW in central Mexico (DL81) is looking for schedules on the satellite, as is VP5JM. RS-13 seems in good shape according to John, K6YK, who recently made several CW contacts on the bird. Waldis, VK1WJ, reports excellent downlink signals.

The RS-12/13 satellite has seen many recent changes in operation during the past weeks. Modes K, T, KT and now mode KA operation have all been reported by a number of stations.

No official word from the satellite controllers has been received. ANS recommends monitoring each satellite carefully to determine the transponder in operation and which mode it is operating in.

RS-12/13 command is now in the hands of Alex Papkov, in Kaluga City, Russia.

John also reports a nice QSO with OH5LK when both stations were right at the edges of the footprint. From St. John, US Virgin Islands, Mal, NP2L, reports contacts with PS7JN, PA0DVM, DC2BB, OK2VLT, and OZ1MY. Frank, PE1KNL, reports contacts with K7XQ, NH6VB, VE6ITV and AL7OB.

JA6BX and OZ1MY both report that AO-10 has started FMing again indicating that another 'sleep period' maybe upcoming.

W4SM tells ANS that he has, using ranging software (and hardware) developed by James Miller, G3RUH, recently made ranging measurements on AO-10 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 and are now based on a 'best fit' of over 300 range measurements.

KITSAT KO-23

Uplink 145.850, 145.900 MHz FM
Downlink 435.175 MHz FM, 9600 Baud FSK
Not operational.

ANS has learned (from the KO-23 ground command team) that the satellite downlink transmitter first tripped off on August 18, 1998. Since that time, KO-23 has been tripped frequently. The transmitter was again off the air on January 17th and (again) turned back on. However, the command team noted the absence of KO-23's downlink on the very next pass. Telemetry shows one of KO-23's battery cells to be very unstable. The command team is analyzing the relationship between the battery life cycle and the downlink transmitter problem. The team has announced operation of KO-23 will be stopped until the team understands the problem completely and has found a workable solution.

Several stations have noted that KO-23's transmitter is once again silent, including W4SM.

UO-22

Uplink 145.900 or 145.975 MHz FM
Downlink 435.120 MHz FM 9600 Baud FSK
Operational.

Chris, G7UPN, tells ANS that the OBC186 flight software on UO-22 crashed recently after operating for well over 500 days.

More information on the satellite is available at the following URL:

OSCAR-11

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

Clive, G3CWV, tells ANS that apart from some ground control activity during the first week in January, it's been another uneventful month for OSCAR-11. During the period 16-December-98 to 16-January-99 good signals have been received from the 145.826 MHz beacon. Telemetry is reported as nominal. Battery voltage is usually around 13.9 volts.

The magnetorquer spin correction counters have continued to be of interest. Recently there have been very few spin counter increments, although the spin period remains around its nominal value of -300 seconds. The Z axis counter increments normally, and all the counters were reset by ground control when a new WOD survey was started.

The internal temperatures have fallen slightly, by about one degree C. They are now 7.6C and 5.8C for battery and telemetry electronics respectively. The current duration of solar eclipse times has continued to provide OSCAR-11 with near optimum conditions, maintaining an adequate power budget while not allowing the internal temperatures to rise to excessive levels.

The single WOD survey, of channels 1, 2, 3, 61 (magnetometers) dated 10-October-1998, was transmitted until 05-January when it was briefly replaced by a survey of the same channels dated 04-January-1999. This was then replaced by a WOD survey dated 06-January-99, detailing solar array currents and array voltage on channels 10, 20, 30, 40 (+Y, -X, +X, V).

The operating schedule is unchanged.

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)

The ASCII bulletin is currently a static message, detailing modes and frequencies of all the amateur radio satellites. There are 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. The 435.025 MHz beacon is normally off.

More information about OSCAR 11 can be found at the following URL:

Downlink 435.822 MHz SSB, 1200 Baud PSK
Semi-operational.

Telemetry is reported as being received on 435.822 MHz at 1200 baud PSK.

ANS has not received any recent updates concerning the status of IO-26. No additional information is available at this time.

TMSAT-1 TO-31

Downlink 436.923 MHz

TMSAT-1 is now open for general access by Amateur Radio operators worldwide. Normal access will allow operators to use the store and forward communications on the spacecraft and also download the high-resolution multispectral images.

Chris, G7UPN, tells ANS that during software loading (and other command activities) ground control stations may close the satellite BBS to general users. This ensures that command activity is not obstructed or slowed by user traffic. This also allows ground control stations to complete these activities much quicker.

Recently, the secondary OBC-386 flight computer software was loaded. The OBC-386 will be made the primary OBC (with a number of advantages) including 128 MB of data storage available for storing images and the availability of two simultaneous uplinks.

ProcMail V2.00G has been released by G7UPN. This software permits the processing of image files from TO-31. ProcMail V2.00G is available for downloading on KO-23 and KO-25. It also has been posted to the AMSAT-NA FTP site at the following URL:

SEDSAT SO-33

Downlink 437.910 MHz FM 9600 Baud FSK
The satellite is not currently available for uplink transmissions.

SEDSAT-1, signifying Students for the Exploration and Development of Space Satellite number one, was successfully launched and placed in orbit on Saturday, October 24, 1998.

SedSat is continuing to perform as it has since launch, transmitting telemetry until the batteries are depleted and then going into safe mode (for about ten hours) and then repeating the process. "The orbital geometry is such that we have had as much as 120 hours of continuous operation from the bird before the batteries die," said Dennis, KD4ETA. Recovery efforts continue.

PANSAT PO-34

Downlink frequency not established.
The satellite is not currently available for uplink transmissions.

PANSAT, developed by the Naval Postgraduate School, was launched from the shuttle Discovery. PANSAT spread-spectrum digital transponders will be available to amateur radio operators in the near future along with software to utilize this technology. The PO-34 command station is located in Monterey, California.

Dan Sakoda, KD6DRA, PANSAT Project Manager recommends 'The ARRL Spread Spectrum Sourcebook' as a good place to start in understanding the spread-spectrum scheme.

The PANSAT Team does not expect the satellite to be available to the Amateur Radio community for another few months.
