AMSAT-DL announces formal go-ahead for space missions "Phase 3-E" and "Phase 5-A"
In July 2002 the AMSAT-DL (Germany) board of directors gave its official green light to develop and build the two spacecrafts AMSAT Phase 3-E (P3E) and AMSAT Phase 5-A (P5A). The high acceptance of the mission goals of these two projects expressed in the recent AMSAT-DL members survey was the final element to arrive at this decision. Both satellites will be created in a common development process by an international team under the leadership of AMSAT-DL. The P3E satellite is to be launched as communication and scientific platform into a highly elliptical orbit around Earth. The second project with the working name "AMSAT-Phase 5-A" is destined to enter an orbit around the planet Mars. This spacecraft will then transmit scientific data to Earth -- data from experiments on-board P5A as well as -- via its repeater function -- from experiments on the Martian surface or the planet's atmosphere.
So far three successful Phase 3 satellites were launched under the leadership of AMSAT-DL. The latest satellite of this series, P3D (now operational as AMSAT-OSCAR 40), was launched in 2000 and demonstrated sufficient bus and propulsion capabilities for a flight to Mars. So AMSAT-DL started a closer investigation into the possibility of such a mission. Based on the existing experience base and the overwhelming interest during the AMSAT-DL International Satellite-Workshop last year, the P5A spacecraft will not only carry scientific experiments, but also subpayloads to be released in direction to the Martian surface. Suitable launch windows to Mars exist in the years 2007 and 2009.
Two or three years earlier P3-E to be launched in an orbit around Earth is expected to continue the successful series of AMSAT Phase 3 satellites. The main task of P3E is to serve as communication platform for the nearly 2 million radio amateurs worldwide. They constitute a network for further exploration of the so called "uncoordinated multiple access", to provide simultaneous and freely available service to a large number of groundstations. Using existing technology and implementing the results of the members survey, several transponders on frequencies between 145 MHz and 10 GHz are planned for P3E. Details will be fixed in a design and payload meeting in the second half of 2002. Additionally the P3-E spacecraft will be an important test bed for some technology needed for the Mars mission. Work on the P3 bus has been started and a number of modules are already under construction.
So far all AMSAT-DL satellite missions in 1980, 1983, 1988 and 2000 were launched with ARIANE launchers from French Guyana into geostationary transfer orbits. The excellent co-operation between Arianespace (with its current ARIANE 5 launch system) and AMSAT-DL resulted in the development of various arrangements for the launch of secondary payloads on-board of ARIANE launches. Thus Arianespace will be the first obvious choice for the launches of P3E and P5A.

Rich Moseson, editor of CQ Magazine, told ANS that CQ Communications Inc., publisher of "CQ Amateur Radio," "CQ VHF" and "Popular Communications" magazines, has filed comments with the FCC supporting the allocation of 2400-2402 MHz as a primary allocation for the Amateur Satellite Service, protecting current and future satellite usage.
In the matter of ET Docket No. 02-98, RM-9949, CQ told the FCC, "We fully support the Commission's proposal to upgrade the existing amateur allocation at 2400-2402 MHz to primary, and to add a primary allocation in the same segment for the Amateur Satellite Service."
Citing the fact that there are currently five amateur satellites using the 2400-2402 MHz band segment and that future satellites will likely use the same band, CQ called upon the FCC to "protect the Amateur Satellite Service from incompatible sharing partners and unintentional interference on uplinks to satellites with international coverage."
CQ's comments also "voiced significant concern that the FCC appears to be placing the interests of unlicensed services on a par with, if not ahead of, those of licensed services." The unlicensed services include cordless telephones and wireless computer networks which have begun to operate on 2 GHz. CQ asked the Commission "to reaffirm its long-standing policy that the interests of licensed operators/services are primary on any frequencies shared by licensed and non-licensed users."
CQ called for the FCC to adopt its proposal to create a "splinter band" at 135.7-137.8 kHz, giving amateur radio its first allocation above 200 meters in nearly a century. The company proposed opening the band to all amateurs with General Class or higher licenses, not imposing mode restrictions and making technical requirements flexible enough to encourage a wide range of experimentation. CQ also strongly supported the creation of a new ham band at 60 meters (5250-5400 kHz), proposing that full amateur power be permitted; that there be no sub-banding, either by mode or by license class; and that the band be open to all amateurs with HF privileges, including CW privileges for those holding Novice Class licenses or Technician licenses with code credit.
CQ's comments were filed electronically and may be viewed in full on the FCC's Electronic Comment Filing System (EFCS) website (http://www.fcc.gov/e-file/ecfs.html) by selecting "Search for Filed Comments," then typing in "02-98" under "Proceeding" on the search page, scrolling through comment summaries until the CQ comments are reached.

Some time ago, Joe VK/G3ZCZ suggested that a telemetry archive for OSCAR-11 would be useful, especially for educational projects.
Clive has now started this archive on his website. Initially it will be just for the current year, and 2001. He will add other years as time permits.
Telemetry from 1993 to 2000 should be relatively easy to archive, as he already has the data on disk. Data prior to 1993 will take a lot longer to archive, as he has to convert it from tape to disk. The early data is often of poor quality, and there are many long gaps where no recordings were made.
If anyone out there can provide any data, particularly for the 1984 to 1993 years, this would be most appreciated. Please e-mail Clive with details. However please DO NOT SEND ANY FILES, before futher discussion.
The purpose of the news archive is to provide an overview of the state of the OSCAR-11 satellite, at the times when the telemetry was captured.
The telemetry archive is at http://www.users.zetnet.co.uk/clivew/. Visit the OSCAR-11 page.

July 22, 2002 UTC - The batteries on AO-27 are starting to show a positive charge. The command team will be turning the automatic data downloads back on. Check the TEPR schedule for information on when the downloads are on. We still need people to monitor and download the telemetry. Visit the AO-27 web page and follow the links on telemetry (http://www.ao27.org/tlm.shtml).

Alex HB9DRI has updated the AO40 Activity Report Logger with a new tool which runs online in a chat room format. He explains that you don't need to download any software, only connect to the web page and begin using it.
Some stations have tried to use the logger as a chat room. This is not the original purpose for the Logger. The new chat room should redirect any chat traffic, keeping the logger available for messages about DXpeditions, status reports, etc. Alex invites interested hams to use the AO40 CHAT ONLINE to receive, send and exchange short info in real time.
The web page is http://www.artieda.net/hb9dri/ao40logger. Alex says this page is a test period. He would appreciate any feedback to be sent to him at firstname.lastname@example.org.

Franco HB9OAB announced new software WlogTracker, a real-time satellite tracking program. This initial beta version is freeware. He mentions one of his goals is to compensate for a bug in WiSP which his testing shows he has accomplished. He describes his program as, "Little, simple and easy ... not a professional application... but working fine!" The exact position of every satellite in orbit is numerically shown to the operator.
He has made it available on his home page at http://www.wlog2000.com. Select WLOGTRACKER.ZIP for download. You may also need to download VBRUN6SP5.EXE if it is not already on your computer.
The WlogTracker program performs realtime the calculation of 60 satellites using standard Keplerian elements such as those on the Celestrak site. WlogTracker has been verified with WIN95/98/ME and he would appreciate finding other users in order to verify the operation on Windows XP or 2000.

International Space Station Expedition 2 crew member Jim Voss got in a few good words for amateur radio when he appeared June 19 before the US Senate Committee on Commerce, Science and Transportation. A retired US Army colonel, Voss cited the value of the Amateur Radio on the International Space Station (ARISS) program in helping to inform and educate youngsters about space exploration and life aboard the ISS as well as to demonstrate scientific principles. ARISS is an international project, with US participation by ARRL, AMSAT and NASA.
Voss said ARISS "offers the opportunity for students to experience the excitement of space flight by talking directly with crewmembers of the ISS via amateur radio." Voss also cited the enthusiastic comments of Allen White, WB4MIO, who helped to coordinate Voss' ARISS contact with Admiral Moorer Middle School in Alabama. "There is no way I can adequately describe the excitement this created in our school and community," White wrote in a letter to Voss. "I think this was the most exciting educational event of the year for these students."
Although not an amateur licensee, Voss participated in several ARISS school QSOs from the controls of NA1SS, the ARISS station, during his duty tour aboard the ISS. The other Expedition 2 crew members were Crew Commander Yury Usachev, RW3FU, and Susan Helms, KC7NHZ. The crew spent 167 days in space aboard what Voss called "a permanent orbiting classroom that brings education and research out of textbooks and into real life."
Voss said the in-flight education programs like ARISS "use the unique environment of space to inspire the next generation of explorers." Taking advantage of technological tools that include amateur radio, he concluded, "students are able to study and explore Earth from space, learn about life aboard an orbiting laboratory, and conduct demonstrations that illustrate scientific and mathematical concepts."

This is a trial version of a proposed single-line satellite status report proposed by Bob WB4APR. The goal is to provide an easy-to-read format of the basic information for each satellite. The ANS Weekly Satellite Report will continue to carry full coverage. One proposal is that a summary report such as this be published on a regular basis such as monthly in one of the ANS publications.
The table below first appeared on the AMSAT-BB mailing list on-line. The ANS editors will monitor the AMSAT-BB list for feedback and questions. More data is planned to be added as this project proceeds.
