Oscar Echo upp mars 2004

Fljande information har kommit om nya satelliten frn AMSAT i USA, Oscar Echo:

AMSAT-North America has announced that launch of the AMSAT OSCAR-E Amateur Radio microsat–the Echo Project — is scheduled to launch March 31, 2004. Earlier plans had called for a May 2004 launch. Echo Project Team member Richard Hambly, W2GPS, reported at AMSAT-NA s Annual Meeting and Space Symposium October 18-19 in Toronto, Canada, that the Echo project has made significant progress in recent months.

A Russian Dnepr LV rocket–a converted SS-18 intercontinental ballistic missile–will carry the approximately 10-inch-square satellite into a low-Earth orbit from the Baikonur Cosmodrome in Kazakhstan.

Echo Project Team member Richard Hambly, W2GPS, reported that the project team powered up the Echo flight hardware in late summer in a flat-sat configuration at SpaceQuest. Data communications, command and control, and attitude control subsystems were tested, in addition to the radio equipment, power systems and cabling.

The satellite will incorporate two UHF transmitters, each running from 1 to 8 W and capable of simultaneous operation, four VHF receivers and a multiband, multimode receiver capable of operation on the 10 meter, 2 meter, 70 cm and 23 cm bands. Echo will feature V/U, L/S and HF/U operational configurations, with V/S, L/U and HF/S also possible. FM voice and various digital modes–including PSK31 on a 10-meter SSB uplink–also will be available.

ISS-nyheter

Tv nyheter angende amatrradio p ISS:

Amateur Radio on the International Space Station (ARISS) Chairman Frank Bauer, KA3HDO, outlined the delivery of the so-called Phase 2 ham equipment to the ISS. A Progress rocked delivered a Kenwood TM-D700E VHF/UHF transceiver to the ISS. The unit will mean a significant boost to the power output of the ARISS initial station gear–from 5 W to 25 W.

A Yaesu FT-100D and SSTV equipment, along with some new headsets, will be taken to the ISS on Progress Flight 14P, Bauer said. That flight is scheduled for January. Additional ARISS gear will not go up until the space shuttle returns to flight in September 2004, however.

Bauer said the equipment still on the ground will be tested in November at the KIS Service Module model facility in Moscow to validate that the Phase 1 and 2 systems are compatible. RF testing will also be conducted.

According to Bauer, current plans call for the Expedition 8 crew of Mike Foale, KB5UAC, and Alex Kaleri, U8MIR, to install the Phase 1 and 2 70-cm hardware after ground tests are complete. Previous crews already installed four Amateur Radio antennas to cover HF, 2 meters, 70 cm and microwave frequencies.

Bauer said the software for the D700 has been set up with five program modes: phone, crossband repeater use, APRS, packet and an emergency mode. APRS probably will be the default mode when a crew member is not actively using the ham station, he predicted.

Crew members typically use non-mission off-time to operate the ARISS gear. Bauer says he s been working with US and Russian space officials to have them dedicate a few additional hours each month for operation and maintenance.
———–

The contingent of space travelers now aboard the International Space Station (ISS) expanded to five early Monday, October 20, with the arrival of the Expedition 8 crew and a European Space Agency (ESA) astronaut who accompanied them into space. Expedition 8 Commander and
NASA ISS Science Officer Mike Foale, KB5UAC, and Russian Cosmonaut and SS Flight Engineer Alexander Kaleri, U8MIR, and ESA stronaut Pedro uque, KC5RGG, joined Expedition 7 Commander Yuri Malenchenko, RK3DUP, nd NASA ISS Science Officer Ed Lu, KC5WKJ, after their Soyuz TMA-3 ransporter docked with the ISS above Russia.

The Expedition 8 crew, which left Earth from Russia Otober 18, will spend the next six months on the ISS. NASA says the two teams will conduct crew hand-over activities during their eight days of joint operations. The formal change of command takes place October 24. The Expedition 7 team of Malenchenko and Lu has been aboard the ISS since April.

Duque, who s flying under a commercial agreement between the Russian space agency Rosaviakosmos and the ESA, will spend the week conducting a series of scientific studies before returning to Earth with the Expedition 7 crew. He s also scheduled to conduct two Amateur Radio on the International Space Station (ARISS) contacts with school groups in his native Spain.

ARISS Vice Chair Gaston Bertels, ON4WF, credits the Union de Radioaficionados Espanoles (URE)–Spain s International Amateur Radio Union (IARU) member-society–with working to obtain the special call sign–ED4ISS–assigned for Duque to use. The ESA launched a competition among all of Spain s schools, and winners will get the chance to interview Duque via ham radio. Bertels says the ESA has established a special Web site (in Spanish) to document Duque s ARISS activities.

This mission mark Duque s second space flight, following his mission on the shuttle Discovery on the STS-95 mission in 1998.

Malenchenko, Lu and Duque are scheduled to depart for Earth October 27 aboard the Soyuz vehicle now attached to the ISS. During his duty tour, Malenchenko was married by proxy to Ekaterina Dmitriev, a native of Ukraine who now lives in Texas. Upon his return, the couple reportedly plans a church wedding in Russia followed by a honeymoon in Australia. Malenchenko is 41; Dmitriev, who lives in the Houston area, is 26. The Soyuz, which carries a crew of three, will remain the prime crew transport system. Russian Progress rockets will transport needed supplies.

Foale, 46, is a veteran of five space flights and has spent a total of nearly 180 days in space–including more than four months on the Russian Mir space station in 1997. During his Mir stay, Foale found ham radio a valuable supplement to conventional Russian and NASA communication systems after the station was damaged in a collision with an unmanned Progress cargo rocket. Kaleri, 47, flew on three Mir missions and has logged 416 days in space.

Information om P3E

Dear friends,

we submit below the final proposal for AMSAT Phase 3E to the Coordination Advisatory Panel. Several suggestions are implemented now. Major changes are in the 5.6 GHz, 24 GHz, and 47 GHz bands.

After careful discussion with Michael, DB6NT, who is our national Microwave Manager in DL, we adopted Graham s proposal to use frequencies in the 2 MHz wide narrow-band segment of the microwave bands. So satellite work and
terrestrial dx will be possible with the same equipment. Thus we expect sort of a synergetic effect , which will attract narrow-band dx enthusiasts to the amateur satellite service, and lead OSCAR amateurs also to terrestrial microwave dx. Additionally this concept could help to protect the important narrow-band segment against other services, and these satellite frequencies could be defended against such threads with the help of dx interested amateurs.

Graham: Could you please contact IARU Region 1 and ask them to agree with this frequency choice?

Hans: Do we have to submit the official coordination form sheet or is this mail sufficient in view of the fact, that this is an AMSAT satellite?

73 de Norbert, DF5DP

P3E frequency proposal (DL6DBN, 03-10-01) 4th draft
=========================================

First of all, we thank all of you who made their welcomed
comments about the 1st, 2nd and 3rd draft. We hope almost
every good advice became part of this 4th and final draft.
The P5 experimental transponder is still in its design
phase. So these frequencies have to be coordinated later.

Most designers of RF-module for P3E are in the state of
ordering flight crystals. So we appreciate an OK or
necessary changes until Mid October. Thank you!

2450 MHz Uplink (S) – 10450 MHz Downlink (X)
——————————————–
TBD
This is the P5A experimental coherent transponder.
It will need a fix frequency relation for coherent
mode and appr. 2 MHz bandwidth for ranging mode.
It will be configurable as linear transponder too
with approximately 50 kHz passband width.

Notes
—–
GB = General Beacon
EB = Engineering Beacon
PB = Passband
RUDAK = Digital Multi-Mode Payload

General note: Except for 145 MHz (see below)
frequencies were chosen not to conflict with
any other amateur radio satellite. Several
frequencies reuse those of decayed AO-13 or
unusable on AO-40. The microwave frequencies
above 5.6 GHz were pre-coordinated among
memmbers of the mm-community.

145 MHz note: Frequencies were chosen to
minimize conflicts with popular downlinks
at 145.800 (ISS) and 145.825 MHz and
uplinks at 145.990 (ISS) and 145.975 MHz
(UO-14). Nevertheless the passband covers
almost all PACSAT-uplinks as 145 MHz is
the most popular amateur satellite band.
Experience with AO-13 and PACSATs in the
early 90s showed that the low power signals
of the transponder passband downlink didn t
harm the LEO packet uplinks.
