> SILVER SPRING, MARYLAND (AMSAT News Service) After a postponed
> deployment in February from the International Space Station (ISS),
> the ARISSat-1/KEDR amateur radio satellite is expected to begin its
> mission on August 3, 2011. This was the word received from Energia
> official, Sergey Samburov during an ARISS teleconference on July 19.
> Deployment of the craft is planned during EVA-29.
>
> NASA TV will cover the EVA live starting at 1400 GMT on August 3.
> 1430: Hatch Open
> 1446: Egress ARISSat-1 and secure to airlock ladder
> 1452: Remove solar panel covers
> 1507: Translate to deploy site, activate PWR, TIMER1 and TIMER2
>       switches, verify LEDs on, and deploy

> ARISSat-1/KEDR is a satellite designed and built by amateur radio
> operators to specifically interest students in scientific and tech-
> nological careers. Through the use of ham radio equipment, students
> and teachers should be able to access and utilize the satellite from
> a classroom environment with minimal set up.
>
> ARISSat-1/KEDR is a cooperative effort between AMSAT, ARISS (Amateur
> Radio on the International Space Station,) RSC-Energia (The Russian
> Space Agency) and NASA. The design, development and construction of
> the satellite was done by AMSAT volunteers. Original plans called
> for the satellite to be housed inside an old Russian spacesuit, but
> when the suit became unavailable, a spaceframe was developed to house
> the radio equipment and solar panels. The new satellite was named
> ARISSat-1/KEDR. Another name for the spacecraft is RadioSkaf-V. The
> transmitted callsign will be RS01S.
>
> The mission was specifically designed as an education-based satellite.
> Some of its broadcast features include a voice identification, voice,
> digital and morse code telemetry, stored image and on-board camera
> transmissions via Slow Scan TV and digital telemetry from a Russian
> science experiment that will measure vacuum in earth's lower atmo-
> sphere. Other aspects of the mission include CW (Morse code) and
> voice message contests to interest students in participating along
> with stored images submitted by students all over the world as part
> of its payload.
>
> ARISSat-1/KEDR Test Transmissions Planned From ISS July 30-31
>
> Test transmissions from ARISSat-1/KEDR are scheduled to begin four
> days prior to deployment at 19:15 UTC on July 30 and then continue
> until 1430 UTC on July 31.
>
> The satellite will be connected to an external antenna mounted on
> the ISS during testing. 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 again for
> 40 seconds.
>
> To listen for ARISSat-1/KEDR signals, FM receivers should be tuned
> to 145.950 MHz.  Even though the satellite will only have an output
> of 250 mW on 2 meters, a standard FM handy talkie equipped with a
> quarter-wave whip antenna should be able to receive the voice ID,
> voice telemetry and greeting messages as the craft passes overhead.
>
> SSTV transmissions may also be demodulated and viewed using a free
> downloadable program such as MMSSTV that is available at:
> http://mmhamsoft.amateur-radio.ca/pages/mmsstv.php.
> For Mac users, Multiscan2 is available at:
> http://web.me.com/kd6cji/MacSSTV/MultiScan.html.
>
> Those planning to monitor voice broadcasts from ARISSat-1/KEDR
> during the July 30 - 31 test are requested to make note of the
> telemetry battery voltage values and UTC time, and then submit
> their records by e-mail to: julytest at arissat1.org.
>
> Digital telemetry will be sent at 145.920 MHz. Given the low duty
> cycle of the spacecraft, those planning to receive the digital
> telemetry are encouraged to record the entire signal band using
> the FunCube dongle or SDR-IQ receivers. Software for demodulating
> the BPSK-1000 telemetry is available at http://www.arissattlm.org;
> the software Quick Start Guide is available on the link on the
> http://www.amsat.org front page.
>
> After it is deployed from the International Space Station,
> ARISSat-1/KEDR is expected to be in orbit for a period of up to
> six months.
