SB SAT @ AMSAT $ANS-210 01 ARISSat-1/KEDR Test Transmissions Planned From ISS July 30-31

AMSAT News Service Bulletin 210 01

From AMSAT HQ SILVER SPRING, MD July 29, 2011 To All RADIO AMATEURS BID: $ANS-210 01

AMSAT NEWS SERVICE SPECIAL BULLETIN ANS-210 In this Special Bulletin:

• ARISSat-1/KEDR Test Transmissions Planned From ISS July 30-31

Test transmissions from ARISSat-1/KEDR are scheduled to begin 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

During the ISS test there will not be an antenna connected to the ARISSat-1/KEDR UHF port The 435 MHz - 145 MHz Linear Transponder will not be active during the test period This transponder will be active once ARISSat-1/KEDR is deployed

FM VOICE DOWNLINK 145 950 MHZ

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

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@arissat1 org

FM SSTV DOWNLINK 145 950 MHZ

SSTV transmissions are included in the cycling FM downlink with station identification RS01S, voice messages, and spoken telemetry

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

If you successfully receive the SSTV transmissions, you can upload the SSTV picture that you received to: http://www amsat org/amsat/ariss/SSTV

SSB BPSK-1000 DIGITAL TELEMETRY 145 920 MHZ

Given the low duty cycle of the spacecraft, those planning to receive and decode the digital telemetry during this test 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

ARISSatTLM TELEMETRY ON-LINE

AMSAT needs your telemetry from ARISSat-1/KEDR both during the test and after deployment from the International Space Station

Since there are no "Whole Orbit Data" storage mechanisms onboard ARISSat-1/KEDR, your submissions are the only way for AMSAT to collect the spacecraft telemetry and KURSK experiment results

If you are running ARISSatTLM and receiving the signal "live" from ARISSat-1/KEDR, then please enable the telemetry forwarding option In the PC version of ARISSatTLM you can do this by selecting "Tools" then "Options" In the "Options" window, replace "NOCALL" with your amateur radio callsign and put a check in the box next to "Forward telemetry over the Internet" The destination will already be filled in with "telemetry arissattlm org"

If you successfully receive the telemetry from a recording (not live), please forward your telemetry CSV file and KURSK telemetry files by e-mail to telemetry (AT) arissattlm org These can be found inside the ARISSatTLM folder on your Windows desktop in the Kursk and Tele- metry folders

And, if you just can't get enough ARISSat-1/KEDR telemetry, remember that you can see the latest telemetry LIVE on your computer or cell phone at: http://www arissattlm org/mobile

This "mobile" page is powered by the submissions from the ARISSatTLM users who forward their telemetry over the Internet

KD5QGR OSCAR STATUS PAGE

Thanks to David Carr, KD5QGR, ARISSat-1/KEDR has just been added to list of satellites at the popular "Live OSCAR Satellite Status Page" at: http://oscar dcarr org/ Although the transponder will not be active this weekend, if you hear the downlink during the test (or if you don't hear the downlink) please submit a report

More information on the transmission schedule and overall mission of ARISSat-1/KEDR can be found at:

The Radio Amateur Satellite Corporation (AMSAT) is a non-profit, volunteer organization which designs, builds and operates experi- mental amateur radio satellites and promotes space education We work in partnership with government, industry, educational insti- tutions and fellow amateur radio societies We encourage technical and scientific innovation, and promote the training and development of skilled satellite and ground system designers and operators Our vision is to deploy satellite systems with the goal of providing wide area and continuous coverage for amateur radio operators world- wide AMSAT is also an active participant in human space missions and supports satellites developed in cooperation with the educational community and other amateur satellite groups

Amateur Radio on the International Space Station (ARISS) is a volun- teer program which inspires students, worldwide, to pursue careers in science, technology, engineering and math through amateur radio communications opportunities with the International Space Station on-orbit crew Students learn about life on board the ISS and explore Earth from space through science and math activities ARISS provides opportunities for the school community (students, teachers, families and local residents) to become more aware of the substantial benefits of human space flight and the exploration and discovery that occur on space flight journeys along with learning about technology and amateur radio
