SB SAT @ AMSAT $ANS-234.01 PHASE 3-D UPDATE AMSAT NEWS SERVICE BULLETIN 234.01 FROM AMSAT HQ SILVER SPRING, MD, AUGUST 21, 1999 TO ALL RADIO AMATEURS BID: $ANS-234.01 Lou, W5DID, tells ANS that vibration testing of the Phase 3-D satellite has been completed successfully. "This is a major milestone for the spacecraft," said W5DID, "the satellite did very well under rigorous environmental tests." Full details of the initial roll out and vibration testing can be found in the July/August issue of the AMSAT-NA Journal. The authors, W5DID and Peter, DB2OS, invite everyone to check out the story and the additional information on the Tom Clark, W3IWI, web site. The W3IWI URL is: http://www.clark.net/pub/tac/p3d.htm W5DID reports the next milestone to be completed is to bring Phase 3-D back to Orlando lab and to verify that all systems are functioning normally following the return trip. Stay tuned to ANS for further details.

Duane Naugle, KO6BT, Symposium chair, recently updated ANS on the October 8-11, 1999 San Diego, California event: ** There is a possibility that SunSat will be activated in FM mode for at least one pass during the Symposium. Stayed tuned to ANS for further details. ** Steve, WB6BDY, will head the team operating the satellite ground station during the Symposium on Sunday, October 10th. Hours will be from 06:00 to 13:00 PDT and as many active satellites will be worked (and contacts made) as possible. ** The IARU Satellite meeting has been moved to Friday evening (October 8th) to allow those who plan to attend (the IARU meeting) the opportunity to go on a field trip planned for Sunday. ** If you do not have travel plans as of yet ask your travel agent to review your options under the listing of the 17th Space Symposium (reference number 559QN). Special reduced fares are available. ** For parents with children under the age of 12 that are planning to bring their children to the banquet, Martha at AMSAT-NA headquarters (301-589-6062) has more information for you, including cost and menu options. Also, for those interested in bringing their families, the hotel has indicated babysitting services will be available through two bonded services. ** Symposium attendees will have the option of visiting two local businesses that deal with satellite communication and spacecraft. QUALCOMM Incorporated has been developing their Globalstar product to provide satellite telephone service. The Symposium tour will be centered on activities taking place by QUALCOMM to characterize and test this system, including satellite antenna/RF sub-system design and call processing. The tour may also include a visit inside one of three Radomes containing a 5.5 meter dish antenna used to track LEO satellites. Following QUALCOMM, the tour will continue to SpaceDev, Inc., whose mission is to engage in commercial space exploration and the long-term development of space. SpaceDev is working on a several projects at their new San Diego facility and Symposium attendees will have a chance to see what this company has to offer. ** Symposium registration information may be obtained from AMSAT-NA headquarters or by visiting the AMSAT-NA web site at: http://www.amsat.org [ANS thanks Symposium chair Duane Naugle, KO6BT, for this information] /EX SB SAT @ AMSAT $ANS-234.03 OSCAR-11 STATUS REPORT AMSAT NEWS SERVICE BULLETIN 234.03 FROM AMSAT HQ SILVER SPRING, MD, AUGUST 21, 1999 TO ALL RADIO AMATEURS BID: $ANS-234.03 Clive Wallis, G3CWV, reports to ANS that OSCAR-11 has passed "yet another month in space transmitting consistent signals" on its 145.826 MHz beacon. "Sufficient telemetry has been captured to verify that the bird is in good health," said G3CWV. OSCAR-11's battery voltage during daylight passes has remained fairly constant with a range of 13.0 to 14.1 VDC. Internal temperatures have risen slightly during the past month, currently reading +1.0C and -0.4C for battery and telemetry electronics respectively. The Wednesday, August 11th satellite pass over the United Kingdom (at 14:13 UTC) recorded slightly lower internal temperatures of -0.2C and -1.4C. G3CWV thinks the 'glitch' may have been caused by the effects of the solar eclipse that occurred that day. Clive tells ANS that he would be very interested to hear from anyone else who may have captured telemetry from the satellite on August 11th. The whole orbit survey (WOD) recently transmitted by OSCAR-11 shows an increased spin period for the satellite (of about 450 seconds per complete revolution). G3CWV says this anomaly has now been corrected by the on-board satellite attitude control system. The current OSCAR-11 operating schedule is unchanged, transmitting internal satellite status along with AMSAT bulletin information detailing modes and frequencies of all the currant amateur radio satellites. The mode-S beacon is operating, transmitting an unmodulated carrier and is a useful source for those testing mode-S equipment for future Phase 3-D operation. Clive reminds ANS readers that reception reports on 2401 MHz are welcome. Please e-mail your reports to: g3cwv@amsat.org. The OSCAR-11 web site offered by G3CWV can provide expanded information on the satellite, including details of the hardware and software required for capturing data. The site also features an archive of raw data for analysis along with several audio files that are excellent examples of the type of data transmitted by OSCAR-11. These audio files will help ground stations identify the various types of data and give an indication of the signal quality required for successful decoding.

The Delta II, which lifted off the pad at Cape Canaveral, brings the total number of Globalstar satellites on orbit to 36. Details on the successful launch can be found at http://spacedaily.com/spacecast/news/globalstar-99i.html. --SpaceDaily ** The NASA/ESA Cassini-Huygens spacecraft recently bid goodbye to Earth as it moved away toward an encounter with Saturn in 2004. The spacecraft is reported in excellent condition as it continues a seven-year flight to Saturn. It will pass by Jupiter near the end of December 2000. The Cassini-Huygens mission is to study Saturn, its magnetic and radiation environment, moons and rings - for up to four years. -ESA ** Arianespace has signed three new launch contracts and agreements for satellite payloads to be launched over the next 12 months. All three satellites are with existing customers: the Indian Space Research Organization with Insat 3A, PanAmSat Corporation with a new satellite and Space Systems/Loral USA with Telstar 7. More information can be found at the following URL: http://www.spacedaily.com/spacecast/news/ariane-99j.html. -SpaceDaily ** With an eye to the new millennium, the Johnson Space Center will open its doors to the public on Saturday, August 28 for its annual Open House, enabling visitors to meet JSC's workforce and see how they plan and conduct human space flight missions. NASA developed technologies will be on display as well. -NASA ** Are you a techie? If so, you may be interested in 'National Techies Day'. This national event will take place on October 5, 1999, and is intended to recognize the important contributions technology has made to all of our lives. For more information check out the National Techies Day Web site at http://www.techiesday.org. --CNET ** The U.S. Air Force Space Command has released details on its investigation into the failure of the inertial upper stage during a Titan IVB launch on April 9th. That launch, from Cape Canaveral, was carrying a classified Defense Department satellite that failed to reach its intended orbit. Details of the investigation can be found at http://www.spacedaily.com/spacecast/news/titan-99e.html. -SpaceDaily ** According to a statement from NASA's Goddard Space Flight Center, astronomers may have actually seen matter falling directly into the gravitational grip of a black hole for the first time. -Sky and Telescope ** JPL has developed an all-silicon micro-gyroscope (for use in space) that will enable satellites to have a continuous balancing system that operates somewhat like our own inner ear.
