ARISSAT-1
RadioSkaf-V
RADIOSKAF-B
KEDRr
RS01S
#37772
(1998-067CK)

ARISSAT-1 (as it is called in the United States) respectively RadioSkaf-V (as it is called in Russia) is part of an amateur radio experiment by the Radio Amateur Satellite Corp., NASA and the Russian aerospace company RSC Energia.
It was brought to ISS on January 30
th 2011 aboard Progress 41. It weighs 30 kg and is housed in a box with a size of about 55x55x40cm.
The additional name "Kedr" is in memoriam of the call sign used by the first person to fly in space, Yuri Gagarin, who made the historic first human spaceflight nearly 50 years ago on April 12
th 1961.
ARISSAT-1 is supposed to transmit 25 greeting messages in 15 different languages, telemetry as well as photos of the Earth on
145.950 MHz using the callsign RS01S.
Here is a description of the band plan including
the transponder-frequencies for up- and downlink. 
Originally it was planned to release ARISSAT-1 by Russian Cosmonauts during a spacewalk set for February 16
th 2011. However this was postponed and Arissat-1 was finally released by Russian Cosmonauts Sergei Volkov, RU3DIS, and Alexander Samokutyaev during an EVA on August 3rd 2011 at 18:43 UTC. It was an exciting event as the release of the satellite was first stopped because of some uncertainty, whether the 70cm antenna for the uplink was missing or broken. It was finally launched towards the end of the EVA and it turned out that the satellite including the linear transponder is working fine.

Aug 3rd 2011

First test aboard ISS

On February 10th and 11th 2011, while ARISSAT-1 was still onboard ISS, it was connected to an antenna mounted outside of ISS and was tested for 2 days. Enclosed SSTV images and audio recordings were received by DK3WN on February 11th 2011 at 2 passes over Germany around 00:18 UTC and 01:54 UTC. Many thanks to Mike DK3WN for the recordings.

This recording of SSTV and voice transmissions of ARISSAT-1 was made by JA0CAW on February 10th 2011 at 21h31 UTC. Many thanks to Tetsu-san JA0CAW for kindly providing the recording.

Second test aboard ISS

On July 30th and 31st 2011 ARISSAT-1 was once more activated while still onboard ISS. It was connected to and outside antenna and operated in low power mode (40sec on every 2 minutes). Its transmission on 145.950 MHz was also relayed by another station in ISS to 437.550 MHz. Enclosed audio file was received and recorded on 437.550 MHz on July 31st 2011 at 03:43UTC by DD1US. Pauses were removed.

On the next pass on July 31st 2011 at 05:18 UTC enclosed SSTV transmission in Robot 36 mode, which was again relayed by ISS to 437.550 MHz, was received by DD1US.

On the same pass enclosed signal was received directly from ARISSAT-1 on 145.950 MHz. Listen to the English voice and see whether you can understand the "secret word" which is changed in each transmission. Received and recorded on July 31st 2011 at 05:21 UTC by DD1US. Pauses were removed.

During the subsequent pass over Central Europe ARISSAT-1 was again activated. Marco Bauer was able to receive enclosed CW and BPSK signals on 145.920 MHz on July 31st 2011 at 06:53 UTC with an Eggbeater antenna. Recording kindly provided by Marco Bauer.

During the same pass also Mike DK3WN received Arissat-1. His recording of the telemetry downlink on 145.920 MHz (CW/BPSK) is of very nice quality. In the first part of the recording you can decode a telemetry packet using the Arissat-software and in the second part of the recording you can decode a KURSK frame. Recorded on July 31st 2011 at 06:54 UTC and kindly provided by Mike DK3WN.

The last pass audible in Central Europe on July 31st 2011 was at 08:30 UTC. In enclosed recording the pauses were removed. The audio signal includes multiple sections including the voice telemetry output in English language and was recorded by DD1US.

Released August 3rd 2011 at 18:43 UTC

Tetsu-san JA0CAW was one of the first stations who received the CW/BPSK beacon signal of ARISSAT-1. Recorded on August 3rd 2011 at 20:56 UTC and kindly provided by Tetsu-san JA0CAW.

Tetsu-san JA0CAW was also able to receive ARISSAT-1 on the next pass over Japan. Recorded on August 3rd 2011 at 22:33 UTC and kindly provided by Tetsu-san JA0CAW.

 On Friday, August 5th 2011 between 05:20 and 05:30 UTC enclosed downlink signal from Arissat-1 was received on 145.950 MHz by DD1US/p. The satellite was apparently not yet spin stabilized and due to its tumbling the signal exhibits a very strong fading. This can be also seen in the SSTV picture which was received during this pass.

In the night of August 6th 2011 I had my receiver monitoring 145.950 MHz and I was able to capture signals from multiple passes between 01:00 and 04:00 UTC. I submitted my log to the ARISSAT-1 / KEDR team and received enclosed nice Award. Recorded by DD1US.

Enclosed 3 minute recording was done on 145.950 MHz on August 6th 2011 between 05:54 and 05:58 UTC by DD1US. The picture shows the corresponding waterfall display of the downlink spectrum. The IF of 10.7 MHz corresponds to 145.950 MHz, the CW/BPSK signal at 145.920 MHz can be seen at the IF of 10.73 MHz. Receiver frequency was not changed thus you can see the downlink signal changing frequency due to doppler effect.

In the night of August 7th I had again my receiver monitoring 145.950 MHz and I was able to capture signals from multiple passes between 01:00 and 06:00 UTC. During these passes interference with emissions form ISS were noticed. You can hear in enclosed recording by DD1US packet radio emissions from ISS as well as interference which sounds like feedback. Investigations are underway.

This audio recording and the decoded SSTV picture was received by Patrick Hajagos on August 29th 2011 at 14:26 UTC. Received on 145.950 MHz in Vienna using an ICOM IC-R20 receiver and kindly provided by Patrick.

5 days before ARISSAT finally decayed enclosed beacon signal was received on December 30th 2011 at 11:02 UTC on 145.915 MHz by Matthias DD1US.

At the same time enclosed SSTV and synthesized voice signal was received on December 30th 2011 at 11:02 UTC on 145.950 MHz by Matthias DD1US.

Also during the subsequent pass over Europe ARISSAT was heard loud and clear. SSTV and synthesized voice signal was received on December 30th 2011 at 13:45 UTC on 145.950 MHz by Matthias DD1US.

Also during the next pass ARISSAT was received in Europe. SSTV and synthesized voice signal was received on December 30th 2011 at 15:07 UTC on 145.950 MHz by Matthias DD1US.

ARISSAT-1 finally decayed on January 4th 2012 at around 7am (+-3 hours).

$50SAT has been a collaborative education project between Professor Bob Twiggs,  Morehead State University and 3 radio amateurs, Howie DeFelice, AB2S, Michael Kirkhart, KD8QBA, and Stuart Robinson, GW7HPW. The primary purpose of $50SAT (Eagle2) was to create a cost effective platform for engineering and science students to use for developing real world skills. The very small pocketcube (5x5x5.7cm) with a weight of only 0.2 kg has no precision mechanical parts and can be built from locally obtained sheet metal. It was successfully launched from Dombarovsky Air Base in Russia on Nov. 21st 2013 07:11 UTC. The satellite went operational shortly after it was released from Unisat-5. It transmits a slow Morse FM beacon as well as FSK RTTY on 437.505MHz. It has been received already during its first pass over UK.

Nov. 21st 2013

This is from the 5th of the 5 available FM Morse beacons transmitted, and is the one which can be changed via an uplink command.  In May 2014 it was changed to "73 AA2TX" to honor Tony Monteiro, AA2TX, the AMSAT-NA VP f Engineering who died on March 26th 2014.  It was recorded on May 18th 2014 at 17:01 UTC at the AMSAT demo booth at the 2014 Dayton Hamvention (gridsquare EM79). Recording kindly provided by Michael Kirkhart, KD8QBA.

This is from a daytime pass near the QTH of KD8QBA (gridsquare EN82), and was recorded by Michael on May 20th 2014 at 15:49 UTC using his FT-817ND operating in LSB mode.  It contains the transmission of RTTY telemetry. Enclosed is also a screen capture of fl-digi decoding the RTTY telemetry (8 bit, 1 stop bit, 100 baud, 630 Hz shift). Recording and screen capture kindly provided by Michael Kirkhart, KD8QBA.

FUNcube-1 was successfully launched on November 21st 2013 and is an educational single CubeSat project with the goal of enthusing and educating young people about radio, space, physics and electronics. It supports the educational Science, Technology, Engineering and Math (STEM) initiatives. FUNcube features a 145.935 MHz telemetry beacon (1200bps BPSK) that provides a strong signal for the primary and secondary pupils to receive. Measuring just 10cm x 10cm x 10cm, and with a mass of less than 1kg, FUNcube-1 also carries a linear transponder. This UHF (435.150 - 435.130 MHz) to VHF (145.950 - 145.970 MHz) linear transponder with approx 500mW PEP output power is used by Radio Amateurs worldwide for SSB and CW communications.
It was reported by Bob WB4SON that up- and downlink frequencies show an offset of 18kHz versus the planned scheme. Without taking into account any doppler-shift an uplink signal at 435.16048 MHz should be received at a downlink frequency of 145.95752 MHz.
