During the July 13, 2011 International ARISS teleconference Sergey Samburov, RV3DR announced that the ARISSat-1/KEDR battery will be charged in late July. A test of the system will be conducted on the ISS from 1915 UTC July 30 to 1430 UTC July 31. The standard ARISSat-1/KEDR 2m downlink band plan should be transmitted. The satellite FM signal will also be downlinked on 437.55 MHz.

During the test ARISSat-1/KEDR will be in LOW power mode, this means that it will transmit about 40 seconds and then shut down for 2 minutes and then transmit for 40 seconds.
Please make note of the spoken telemetry battery voltage values and UTC time, and then submit your records by e-mail to: julytest@arissat1.org.
The linear transponder mode will be activated once the satellite is deployed.



ARISSat-1 is a new Amateur Radio satellite that will be deployed from the International Space Station (ISS) during a space walk in early August.

It is currently onboard the ISS and on the weekend of July 30-31 the satellite will be connected to external antennas of the ISS enabling Amateurs to communicate through it's linear transponder using SSB/CW and receive it's FM, BPSK and CW downlinks. The FM downlink will also be transmitting Slow Scan TV that can be received using the free MMSSTV software.

AMSAT-UK intend to use the GB4FUN station equipment to listen to the various ARISSat-1 signals and, hopefully make a few contacts through the SSB transponder.

In addition they will be experimenting with the use of FUNcube Dongle software defined radios to receive the ARISSat-1 signals with a variety of different antennas.

The colloquium is being held on July 30-31 at the Holiday Inn, Guildford, GU2 7XZ. It is open to all Radio Amateurs and SWL's. Either day passes or full packages comprising overnight accommodation and meals are available. For futher information see http://www.uk.amsat.org/colloquium-2011/

The AMSAT-UK International Space Colloquium takes place in Guildford this weekend, July 30-31.

BATC and AMSAT volunteers will be streaming video of the event live, enabling it to be seen around the world.

Clearly a webcast cannot match actually being there, with the opportunity to chat to satellite builders and inspect space hardware, but if you can't get to Guilford then the webcast provides the next best thing.

The webcast will be at http://www.batc.tv

Med vesoljskih sprehodom na satelitu manjka ena izmed anten....uhhh
in tako se satelit vrača na krov Mednarodne vesoljske postaje. :cry:

in ja, saj ne moreš verjeti, celo anteno so uspeli najti po parih urah ;)
Satelit pa je v orbiti ;) od 18.43 (3.8.2011)

Pozdravljen Andrej in ostali,

Kot prebiram je UHF antena le konektor brez sevalca.

28. julija, ko je bil satelit priključen na ISS antene mi ga je uspelo ujeti, čeprav ob tistem času ni imel ugodne pozicije za Evropo. Voice telemetrija je bila slišna b.p. in tudi SSTV se je lepo slišal. Postaje nisem imel povezane s PC, da bi poslano sliko tudi sprejel.

Vsekakor bo še zanimivo.

Tilen bo verjetno držalo, kar si napisal.
Včeraj so bile različne variante, da je antena ,da je in itd. Nekaj se pisalo tudi o poškodovanih
sončnih celicah. Upam pa da se bo dalo kaj narediti preko transponderja, kljub takšni anteni.
Verjetno se bo dalo ujeti veliko slik, tako da akcija...:)
