- 1. Phase 3C Poised For launch
-
- All is in readiness for the launch of AMSAT's Phase 3C satellite in the first
- week of June. The fueling operation of the joint AMSAT-NA and AMSAT-DL teams
- was completed without incident and the spacecraft stands ready for launch as
- soon as the launcher itself is ready. Sources indicate June 7 or June 8 are
- the most likely launch dates. The actual launch date will firm when the next
- launch, that of an Intelsat spacecraft on the V-23, has been accomplished.
- That launch is currently slated for May 17 or 18. If the launch of Phase 3C on
- mission V-22 does occur on or about June 7 as now planned, the launch window
- will be about 1200 UTC which is morning in Kourou, French Guiana, the launch
- facility of the European Space Agency.
-
- The new Ariane 4 launcher was due to be rolled out for its first public
- display, virtually a coming out party for the big new rocket, on Friday, April
- 29.
-
- The fueling team, team 2, returned to its home bases recently. Monitoring of
- the spacecraft telemetry which is a major task of Team 3, will continue
- through until launch day.
-
- Phase 3C will be placed into general operation about one month after launch
- depending on the number and timing of on-orbit kick motor burns implemented.
- The operating frequencies have been published in ASR and will be repeated
- periodically in these bulletins. ASR is a member service of AMSAT-NA. A
- launch information net will provide pre-launch, launch day and post-launch
- coverage of the launch week. The exact launch net schedule will be known only
- as we approach launch day. Watch for announcements in these bulletins
- throughout May and early June.

- 2. Skitrek Progress Report #14, April 30, 1988
-
- The Amateur Radio supported Transpolar Skitrek got underway on April 28th
- after an event filled 2 day stay at the North Pole. Media coverage increased
- as Russian TV, the Cable News Network and CBC-TV covered activities at the
- Pole. As of April 30th, the skiers were at 89d 37.9m N and 94d 29.8m W. During
- the Trek the UO-11 Digitalker has been steadly reporting the "moving groups"
- position. The buzzing sound heard alternating with the Digitalker is the
- digital data which encoded the latest bulletin from the University of Surrey.
- The digital data carries telemetry as its other major function but this was
- temporarily suspended during the special program established for the press
- conference. Here is the latest bulletin, as transmitted by UO-11:
-
- **** UoSAT-OSCAR-11 BULLETIN - 132 28 April 1988 ****
- UoSAT MISSION CONTROL CENTRE,
- University of Surrey, Guildford, Surrey, GU2 5XH, England
-
- ** UoS TEAM MEMBER JOINS SKITREK AT NORTH POLE **
-
- The joint Canadian-Soviet SkiTrek reached the North Pole on 26th April 1988,
- 54 days and 1000 km after setting out on their "Transpolar Ski-Trek." Since
- departing from northern USSR on 1 March, the team has received daily progress
- updates of their exact location from the UoSAT-2 DIGITALKER.
-
- Arrival at the North Pole marks the half way point in the 2000 km trek from
- Cape Arktichesky on the Severnaya Zemlya archipelago, USSR, to the Cape of
- Columbia on Ellesmere Island, Canada. The team was joined at the Pole by
- journalists from around the world - flown in to a unique North Pole press
- conference. In recognition of the assistance that UoSAT-2 continues to
- provide for the skiers, Michael Meerman (G0/PA3BHF), member of the University
- of Surrey's UoSAT Spacecraft Engineering Research Unit, was invited by the
- Soviet Ski-Trek leader to attend the press conference at the North Pole.
- Michael is the UoSAT Team member in charge of the daily operation of both
- UoSATs, and has been responsible for loading the Ski-Trek reports to UoSAT-2.
-
- Michael travelled to Moscow on 24 May, and travelled from there to Sretney
- Island on the 25th. From Sretney, he made contact with G3YJO at UoS via
- 20-metre SSB. On the 26th after some delays caused by bad weather, Michael
- arrived at the pole, where he was able to interview members of the Ski-Trek
- team.
-
- Thousands of school children throughout the world have been tracking the
- skiers by listening to the UoSAT-2 DIGITALKER, and learning about polar
- exploration through weekly Ski-Trek updates authored by AMSAT-NA member Rich
- Ensign (N8IWJ). Michael Meerman carried a list of their questions with him to
- the pole, to get the answers directly from the skiers themselves.
-
- As the Ski-Trek continues towards its final destination in Canada, UoSAT-2
- will also continue to provide daily position updates, demonstrating the value
- of the UoSAT-OSCAR satellites to education and polar communications.
-
- ** DIGITALKER ON UOSAT-1 **
-
- Many of those listening to the Ski-Trek DIGITALKER reports will be interested
- to know that the UoSAT-OSCAR-9 spacecraft (UoSAT-1) also carries a DIGITALKER,
- which is activated every week. From 0000 to 1500 GMT on Thursdays, the UoSAT-1
- DIGITALKER "speaks" spacecraft telemetry values in plain language. The best
- UoSAT-1 passes usually occur around 8 or 9 o'clock local time each morning and
- evening. Pass this information on to those who have only been listening to
- UoSAT-2, but would like to try more experimentation with satellites.
-
- ** SEND ACTIVITY REPORTS **
-
- As always, we at UoS are interested to hear what you are doing with the UoSAT
- satellites. If you have been using the DIGITALKER to follow the Ski-Trek,
- please send us (address above) a brief description of your activity.
-
- You can send reports to UoS through amateur packet radio if you are in the UK,
- Australia, New Zealand, South Africa or the USA. Just address your messages so
- that they will be forwarded to your local UoSAT-2 DCE gateway station.
-
- This report has been prepared by Rich Ensign, N8IWJ, AMSAT Science Education
- Advisor For Use With The AMSAT Teachers Guide "Exploring The High Arctic From
- Your Classroom" Michael Meerman's report from the Pole will appear in our next
- Progress Report to be issued on May 6, 1988.

- 3. Record Crowds Flood Dayton Hamvention
-
- Early reports suggest record crowds have made the 1988 Dayton Hamvention the
- largest in history. Reports are circulating that upwards of 30,000 attended
- by Saturday, April 30. If so, this would be at least 20% above the previous
- high attendance mark of 25,000.
-
- Traffic at the AMSAT booth was brisk throughout the weekend. Interest in
- Phase 3C was high and a significant proportion of visitors were well familiar
- with the progress towards launch of the new satellite. Questions concerning
- suitable equipment for Phase 3C and where to find it predominated the
- discussions at the booth.
-
- Doug Loughmiller, KO5I, led a team of AMSAT volunteers working the double
- booth. The new AMSAT Phase 3C poster was on display for the first time. The
- booth also included a strong TAPR contingent.
-
- AMSAT held two forums over the weekend. The Saturday forum moderated by KO5I
- featured Chairman Jan King, W3GEY who spoke on Phase 3C progress, Phase 4 and
- PACSAT. President Vern Riportella, WA2LQQ, gave a presentation on future
- projects and Garth Hamilton, VE3HO, gave an update on the SKITREK project. A
- packed house of at least 250 attended the forum on Saturday. An additional
- forum was planned for Sunday and was expected to be well attended too.
-
- Member renewals were strong through press time on Saturday suggesting interest
- levels are increasing with the approach of the Phase 3C launch.
-
- Equipment suitable for Phase 3C was much in evidence with some entries present
- even for Mode S. Downeast Microwave, Spectrum International, PX Shack and
- Microwave Modules were among those offering off-the-shelf equipment for 24 and
- 13 cm. The auto-tracking interface called the "Kansas City Tracker" which
- works with the IBM series of computers was also on display as was the Mirage
- autotracking system.
-
- Near-perfect weather and a very upbeat crowd at Dayton's Hara Arena punctuated
- the generally optimistic feeling which seemed very much in evidence. This is
- in contrast to some years in which a general pall hung over the event for
- reasons which remain unclear. In this year's event, however, there was a good
- feeling about the overall event and both attendees and vendors seemed to
- reflect a generally buoyant atmosphere. This optimism was very much in
- evidence at the AMSAT booth which stayed pleasantly crowded virtually from the
- opening bell and throughout the weekend.

- 4. Short Bursts
-
- AMSAT is deeply saddened to note the passing of one of its most devoted
- members, Cy Williamson, VE3TW, who became a silent key in mid-April. Cy had
- been an active AMSAT member for many years and was a familiar voice on the
- AMSAT 75 meter East Coast net and his distinctive fist was easily recognized
- on AO-10. He will be deeply missed.
-
- ***
-
- AO-10 should be ready for use by mid-May according to control stations polled
- recently. The improving sun angles will allow a return to general operations
- in a couple of weeks they say. Since the attitude control system on AO-10 is
- inoperative, it is necessary to await the natural changes in geometry between
- AO-10 and the sun for sufficient power to operate the satellite. The season
- of favorable sun angles will begin soon say the command stations. Watch for
- an announcement soon on the availability of AO-10 for operation.
-
- ***
-
- Gordon and Molly Hardman (KE3D and N3CHZ respectively) recently became the
- proud parents of of lovely son Edward Ryan. Gordon is a key member of the
- Phase 3C and PACSAT engineering team in Boulder, Colorado.
