RUDAK och GPS aktiva igen

Enligt nedanstende information frn Oscar-40 teamet finns det nu tillrckligt med kraft fr att ter igen aktivera GPS och RUDAK.

With the improved solar angle, we now believe that we have enough power to activate RUDAK, GPS, and CEDEX. Both the GPS and CEDEX experiments have yielded exciting preliminary data and the experimenters, including the folks at NASA, are anxious to gain as much additional information as possible. Therefore, if all goes according to plan, the above schedule will be in effect for Orbit 701 and 702 (Amsat AO-40 orbit numbers as in telemetry, subtract 1 from recent NORAD keps).

Note that from MA = 128 to 190, the middle beacon will be off and one or both RUDAK downlinks will be active. After Orbit 702, if all software has been successfully loaded, the length of the RUDAK interval is scheduled to be decreased to MA =128 to 160.

Several stations around the world are set up to download RUDAK data. On passes where active downloading is not scheduled, and images are needed for ALON/ALAT calculation, the RUDAK pass may be inactivated, either partially or completely, or the middle beacon may be activated in addition to the RUDAK downlink, at least temporarily, while image files are downloaded.

Nyheter om ISS och RS-21

Anders, SM0DZL, lmnar fljande info:

25 april kl 0626z startade Soyuz-TM 34 frn Baikonur i Kazakhsatan. Ombord fanns Yuri Gidzenko , Roberto Vittori/IZ6ERU samt turisten Mark Shuttlewoth/ZS RSA. Man dockade med ISS 27 april och under vistelsen ombord har Mark aktiverat NA1SS. Mark har tutat p bde 145.800 och 143.625.

Landningen med Soyuz-TM 33 berknas ske den 4 maj om aftonen p den kazakhiska stppen.

Angende RS-21: Hdanfrd tidigarelagd till 3-4 maj.
Jag ser ofta RS uttytt som RADIO SPORT men p ryska str det fr Radioljubitelxskij Sputnik = amatrradiosatellit.

Bra aktivitet på 145.825 MHz

Hkan SM7WSJ lmnar fljande rapport:

Hej! har ni mrkt vilken aktivitet det r p 145,825? scannern lser rtt ofta nufrtiden och tydligen kommer det mer och mer sm student cubesats framver.

Nice conjunction of all three 145.825 satellites, PCsat, UO-11 and Kolibri over the east coast of USA at same time at about 1910z! I was copying packets on my beam pointed at PCsat, but UO-11 was in the background in between packets, and I could hear the CW from Kolibri even on the FM rig due to the beat tones of the CW with UO-11…

First time I have heard all 3 at once.

Två nya amatörradiosatelliter på gång

Enligt tidigare bulletiner frn AMSAT-F (Frankrike) ska tv picosatelliter skjutas upp imorgon den 3 maj tillsammans med satelliten SPOT-5. En Ariane-4 raket str fr lyftet upp i rymden.

P AMSAT-F hemsida kan vi lsa att den ena satelliten ska snda p 145.840 MHz och den andra p 435.270 MHz. De kommer att snda digitalt tal och telemtri enligt AO-40 format (400 bps BPSK), r batteridrivna och berknas fungera i 40 dagar i en bana p ca. 800 km hjd. Sndarna kommer sls p 10 dagar efter uppskjutningen.

Ny avancerad satellit, AMSAT-OSCAR E

AMSAT-NA i USA meddelar med nedanstende text att en ny avancerad mikrosatellit ska byggas, med mlet att skjuta upp den i slutet av r 2003. Projektet fr namnet AMSAT-OSCAR E. Ls mer nedan:

AMSAT-North America has started construction of a new low-earth-orbit (LOW) communications satellite. Although the satellite will be similar in mass and size to the original AMSAT MICROSAT design, it will incorporate all new, leading edge electronics and RF technology.

Robin Haighton, VE3FRH, AMSAT-NA President, discussed the new project at the organization s Board of Directors meeting held in Washington, DC, April 20-21, 2002. I am very pleased that we are embarking on a brand new satellite project. I am particularly pleased that this new project will operate as an EZ Sat, as well as serving as a test bed for new and exciting technologies. he said.

Returning to the original pre-launch numbering system used in many of the earliest AMSAT-NA developed satellites, the new bird will be named AMSAT-OSCAR E (Echo) until launch. Plans call for the satellite to contain analog and digital VHF/UHF FM transponders similar to those carried on the UOSAT-OSCAR 14 and AMRAD-OSCAR 27 satellites currently in orbit. In addition, the new satellite will have the capability to host one or two other experimental payloads.

Continuing an approach used in past projects, AMSAT-NA has partnered with an outside contractor, SpaceQuest, Ltd. of Fairfax, Virginia, who will assist in building the satellite bus. AMSAT volunteers are responsible for the design, development, integration and testing of the various experimental payloads.

Dr. Tom Clark, W3IWI, AMSAT-NA BOD member and one of the spark plugs for the original MICROSAT project noted that, The last major program that AMSAT-NA managed was the MICROSATS and this is a superb chance for us to update that legacy with all-new technology. He went on to note that, We now have accumulated about 70 years of on-orbit experience with the MICROSAT design since our original flock
were launched back in 1990, with several other satellites of that same basic design now on the drawing boards. The design is a true classic.

The spacecraft is now slated to be ready for launch in late 2003. A number of affordable launch opportunities are being actively explored.

AMSAT is very proud of its long tradition of excellence and the contributions it has made to the advancement of space communications, space education and the space sciences. AMSAT-OSCAR E will be a new vehicle for Amateur Radio to continue that quest for communications technologies for future generations.
