OSCAR Zero
Moon
#00001 |
Radio amateurs
use the Moon as a passive repeater (reflector) and thus
call him sometimes OSCAR Zero. The first radio amateurs
who successfully received signals bounced off the moon
were Ross Bateman (W4AO) and Bill Smith (W3GKP). They
received the echo on 144 MHz in 1953. |
Jul
20th 1969 |
 Enclosed
Moon Bounce SSB transmissions were done from KP4BPZ
in Arecibo, Puerto Rico, using the 1000 foot diameter
radio telescope dish. KP4BPZ was running about 500 watts
on 432 MHz. This recording was made by Roy W0SL in Florissant,
Missouri on July 3rd, 1965.
|
The moon
can be used as a reflector also at Microwave frequencies
as demonstrated in the next few recordings kindly provided
by Michael OH2AUE. This recording is from the first
Finish 10 GHz EME QSO (in CW) with WA7CJO. OH2AUE built
the equipment and the 6.4 meter dish from OH2AXH was
used. |
The first
Finnish 5.6 GHz EME QSO (in SSB) took place in 1995.
You can hear the voice of OH2AXH as well as the echo
of the reflected signal loud and clear. TRX from OH2AUE
and 6.4m dish from OH2AXH. Recorded in 1998 by Michael
OH2AUE. |

OSCAR 1
#00214
(1961-034B) |
This first
Amateur Radio Satellite was built by a Californian group
of Amateur Radio operators. They called their activities
"Project OSCAR" (Orbiting Satellite Carrying
Amateur Radio). OSCAR-I was launched together with the
reconnaissance satellite Discoverer-36 (see picture
of special letter enclosed) from Vandenberg, AFB aboard
an Agena rocket. The primary payload was a spy satellite
of the CORONA series. OSCAR-I had a polar orbit of 431km
x 245km with an inclination of 81°. It had a weight
of 4.5 kg and transmitted a simple "HI-HI"
in morse code on 2m (144.983 MHz) with 140 mW power
using a single monopole antenna. The speed of the HI-HI
message was controlled by a temperature sensor inside
the spacecraft. OSCAR-I operated 3 weeks until its batteries
were discharged and decayed after 312 orbits on January
31st 1962. Recording kindly
provided by W0SL. |
Dec
12th 1961 |
Lance Ginner K6GSJ was
very much involved in the build and launch of OSCAR-I
to OSCAR-IV. He kindly provided some very interesting
and rare pictures of OSCAR-I.

OSCAR
II
OSCAR 2
#00305
(1962-022B) |
OSCAR II
was built by the same team and was very similar to OSCAR
I with some slight  modifications
which were:
1.) changes to the surface thermal coatings
to achieve a cooler internal spacecraft environment
2.) modifications of the sensing system so that the
satellite temperature could be measured accurately as
the batteries decayed
3.) reduction of the transmitter
output power to 100 mW to extend the life of the onboard
battery.
OSCAR-II was launched from Vandenberg,
AFB aboard a Thor Agena B rocket with Discoverer-43
(picture of special letter on the right). Discoverer-43
was another payload of the CORONA series. It was inserted
into a 292km x 110km polar orbit with 74° inclination.
OSCAR-II lasted 18 days before it decayed on June 21st
1962. |

#01293
(1965-016F) |
OSCAR-III
had a weight of 16.3kg and was launched from Vandenberg,
AFB on a Thor Agena D rocket together with a classified
satellite. It had a nearly circular orbit (892km x 865km,
inclination 70°). AO-III was the first amateur satellite
to operate from solar power and relay voice contacts
in the 2 meter band (VHF) through a 1 W 50 kHz wide
"translator" i.e. a linear transponder (146
MHz uplink and 144 MHz downlink). A total of 176 two-way
contacts were reported through OSCAR-III during 247
orbits of active translator operation (18 days). Contacts
were made by 98 participating stations, 67 from North
America and the remaining 31 from Europe. It also had
two radio beacons sending a continuous signal for tracking
and propagation studies respectively telemetry data
about temperatures and battery voltages. |
Mar

Below please find some
articles about OSCAR-III.
 
 |
In the years of OSCAR-III
tracking a satellite was not as easy as running a colorful
application on a PC. In 1965 Joe K0VTY built a tool
for satellite pass predictions. Enclosed please find
a picture of his "Half Globe".  Here
is how it works: The half globe was a surplus school
world globe. It comes apart rather easily at the equator.
You put the northern hemisphere of the globe on a wooden
base with some wood blocks at the edges of the globe
to allow it to rotate and remain centered.  Select
a place on the wood base to be the reference to measurements.
This is the starting point for a piano wire that passes
over the globe as if it were at a LEO distance above
the earth (globe). The piano wire terminates on the
other side of the globe in a place that is equal to
the passage of the satellite over the earth.  Along
the wire are string knots representing a distance of
ten minutes. Missing on the pictures is a thin poly
sheet, 6 inches in diameter, that had a inner hole 2
inches in diameter to represent an omni-directional
radiation pattern centered on his location. Thus he
could see his satellite horizon for the bird depending
on the location of the wire. |

OSCAR 4
#01902
(1965-108C) |
OSCAR-IV was launched
from Cape Canaveral onboard a Titan 3C piggyback with
three United States Air Force satellites and had a target
orbit which was geosynchronous. However due to a malfunction
of the 3rd stage of the Titan rocket it was inserted
into a highly elliptical orbit (29120km x 168km, inclination
26°). This 18.1kg satellite was a project of the
TRW radio club in Los Angeles and included a 10 kHz
wide linear transponder (144.1 MHz uplink and 431.94
MHz downlink) with 3W output power. While its beacon
remained on intermittently for several months, only
7 two-way contacts were made. Overall OSCAR-4 operated
85 days and decayed on April 12th
1976. |

#04321
(1970-008B) |
AO-5 was built at Melbourne
University and was the first amateur satellite to be
remotely controlled. Development was sponsored by AMSAT
and commenced in 1966. Its weight was 17.7 kg and the
dimensions were 0.30m x 0.43m x 0.15m. It was launched
from Vandenberg, AFB aboard a Thor Delta rocket. Its
circular orbit (1477km x 1434km) was inclined 102°.
It employed bar-magnet stabilization to prevent tumbling.
The battery (9 kg) powered transmitter sent telemetry
on 2 meter (144.050 MHz at 50 mW) and 10 meter (29.450
MHz at 250 mW) bands. The 2m beacon remained operational
for 23 days, the 10m beacon for 46 days respectively. |

(1972-082B) |
AO-6 was launched from
Vandenberg, AFB aboard a Delta 2310. Its circular orbit
(1455km x 1449km) was inclined 102°. Equipped with
solar panels powering NiCd batteries this satellite
had a weight of 16.0kg and lasted 4.5 years. It was
the first amateur radio satellite with a complex control
system using discrete logic. It featured 3 transponders
using 10m, 2m, 70cm bands as well as a Codestore unit.
The transmit power was 1.5 Watts. The first satellite-to-satellite
relay communication was based on AO-6 and AO-7. |

AMSAT
OSCAR 7
(Phase-2B)
#07530
(1974-089B) |
AO-7 was built by a multinational
team under the direction of AMSAT North America.
AO-7 carries two linear transponders: Mode A (145.850-950
MHz uplink; 29.400-500 MHz downlink) and Mode B (432.180-120
MHz uplink; 145.920-980 MHz downlink). It also contains
two working beacons on 29.502 and 145.972 MHz.  A
third beacon on 435.1 MHz has been reportedly heard
sporadically and a fourth beacon on 2304.1MHz was never
activated. In 1981, after 7 years of successful operation,
AO-7 ceased transmissions due to battery failures. However
another 21 years later, in mid 2002, it started to become
operational again. Until today, 35 years after its lauch,
its transmitter is active as long as the satellite is
not in eclipse i.e. its solar panels are lit by the
sun. After emerging from an eclipse AO-7 may turn on
in any of the modes explained above. |

OSCAR 8
(Phase-2D)
#10703
(1978-026B) |
AMSAT-OSCAR 8 was launched
as secondary payload with LandSat 3 (ERTS 3) and PIX.
This box shaped satellite (38cm x 38cm, 33cm high) had
a weight of 27.2 kg and was another cooperative international
effort of the United States, Canada, Germany and Japan.
Similar store-and-forward service as AO-7. Carried Mode
A (145.850-900 MHz uplink and 29.400-500 MHz downlink)
and Mode J (145.900-146.000 MHz uplink and 435.100 MHz
downlink (inverted)) linear transponders and telemetry
beacons on 435.095 MHz and 29.402 MHz. For VHF a circularly
polarized canted turnstile antenna was used whereas
the UHF antenna was a quarter wave monopole. The antenna
system was completed by a half-wave dipole for HF. AO-8
was operational until the batteries failed on June 24th
1983. |

AMSAT
Phase-3A
P3A
(launch failed)
|
AMSAT Phase-3A was the
first satellite of the AMSAT Phase 3 program.  It
was jointly developed by AMSAT Germany and AMSAT North
America. This 92.2 kg satellite included a 50 Watt high
power Mode-B linear-transponder with 435 MHz uplink
and 145 MHz downlink. Phase-3A had an on board Star-13C
kick motor which would have boosted it into a highly
elliptic Molniya orbit.  However
the satellite was lost during launch (the first Ariane-1
launch carrying actual payloads). P3A would have been
named AMSAT-OSCAR 9. An English report about the launch
failure was printed in AMSAT magazine "Orbit"
and can be downloaded by clicking on the icon to the

Ulli DK4VW, who was in
Kourou at the launch site, reported frequently about
the preparations of the launch and especially of the
launch campaign itself. The recordings below (on HF
bands) were kindly provided by DK2ZF and include very
interesting and dramatic reports. |
In this
contact Ulli DK4VW in Kourou is reporting the status
of the launch preparations to Karl DK4ZC (in German). |
More details
of the launch preparation discussed in a contact between
the club station FY7KRU operated by Ulli DK4VW and Rolf
DK2ZF (in German). |
Another
update was given on the day before launch by Ulli DK4VW
to Rolf DK2ZF (in German). |
Contact
between Jan WA3NAN in Maryland and Ulli FY7KRU in Kourou
(in English). |
FY7KRU
reports to DK4ZC (in German) and WA3NAN (in English)
the interruption of the launch campaign because of an
anomaly in the valve of the second stage. The countdown
was reset to T-6 minutes. |
DJ4ZC
Karl asks FY7KRU Ulli about post launch data to calculate
keplerian elements. |
A second
interruption of the launch campaign was reported by
Ulli FY7KRU. The countdown was reset again to T-6 minutes. |
The countdown
was restarted but shortly after interrupted again for
5 minutes. |
The launch
window was getting tight now. This recording starts
3 minutes before launch and includes the launch. A few
minutes after the launch the CAT receiver signal was
noisy, which indicated already a problem. |
Soon after,
Ulli FY7KRU had to report a loss of the telemetry  signals
and then the loss of the rocket and satellite. He stated
"Wir sind sehr traurig" (we are very sad).
This was certainly also the mood of the team which got
together in Kourou. |
After
the failed launch HB90P explained to DK2ZF in amazing
details the chain of events which caused the problem
(see also last picture left). |

RS 3
Radio-3
#12997
(1981-120A) |
RS-3 to RS-8 were jointly
launched on one C-1 rocket from the Northern Cosmodrome
at Plesetsk to 1600 km altitude.
They were supposedly
based on small Strela-1M (arrow) space-frames which
were originally designed for Russian Military store/dump
communication spacecrafts. Cosmos-3M launchers were
used to launch octets of these store/dump satellites
into one of three orbital planes to provide excellent
global coverage. More than 200 small Strelas each with
a weight of 74 - 80 kg were launched between 1970 and
1992.
Fortunately some spare Strela-1M space-frames
could be used for the RS 3-8 satellites with adapted
payloads developed by students of the University of
Moscow. Like RS-1 and RS-2, the six new Radiosputniks
each weighed approx. 40 kg and were cylinders 43cm in
diameter and 38cm long. At that time, this was the largest
clutch of Amateur Radio satellites ever orbited at one
time. Many thanks to Al GM1SXX for this background information. |

AMSAT
OSCAR 10
(Phase-3B)
#14129
(1983-058B) |
AMSAT OSCAR 10 was launched
on June 16th 1983 piggyback
with the European test satellite ECS-1 on Ariane 1-06.
Due to a collision with part of the launch vehicle after
separation the onboard propulsion system was damaged
and thus AO-10 did not reach its targeted Molniya type
orbit. Nevertheless AO-10 was very successfully used
by many radio amateurs worldwide. It featured 2 beacons
and a Mode B linear transponder.
General beacon:
145.810 MHz CW/RTTY/PSK
Engineering beacon: 145.987
MHz PSK
Mode U/V (B) linear transponder (inverting):
Uplink: 435.027 - 435.179 MHz
LSB/CW
Downlink: 145.825
- 145.977 MHz USB/CW
In December 1986 the
onboard computer of AO-10 failed due to radiation damage
of the memory chips. Since then the satellite did turn
its transponder or beacons randomly on/off. Under normal
conditions the transponder is on and the general beacon
transmits an unmodulated carrier. |

Due to
the collision also the antennae were damaged. Therefore
you can hear a strong spinning sound of the transponder

AMSAT
OSCAR 13
(Phase-3C)
#19216
(1988-051B) |
AO-13 was
launched on June 15th 1988
on an Ariane-4 rocket from Kourou/French Guiana. It
was at its time the most powerful Amateur Radio communications
satellite. AO-13 was in a highly elliptical orbit, which
provided the spacecraft outstanding DX potential over
the world's most populated regions (Asia, North America
and Europe).
AO-13 carried four beacon transmitters
and four linear transponders. The beacon downlinks were:
Mode V (General beacon): 145.812 MHz CW/RTTY/PSK
Mode V (Engin. beacon): 145.985 MHz PSK
Mode U (General
beacon):435.652 MHz PSK
Mode S (Engin. beacon):
2400.664 MHz PSK
The most used transponders were:
Mode U/V (B) Linear Transponder (Inverting):
Uplink:
435.573 - 435.423 MHz LSB/CW
Downlink:
145.825 - 145.975 MHz USB/CW

 In
November 1998, after 8 years of operation, the solar
panels failed as they got very hot during low perigee
passes in the dense atmosphere. The plot enclosed shows
such a transition recorded on November 23rd
1998 in orbit 6479. AO-13 finally decayed on December
5th 1996. |

The first
ZRO test (in memoriam of K2ZRO) was conducted via AO-10
on May 5th 1985 at 11:30 UTC
in Mode B (145.850 MHz downlink). From then on ZRO tests
were regularly conducted on AO-10 and later also on
AO-13. During these tests a Morse signal with decreasing
power level was transmitted and thus allowed the user
to evaluate the performance of his receiving system.
Enclosed you can hear the ZRO transmission on 145 MHz
via OSCAR 13 from Andy MacAllister, on 24 April 1993.
The file contains about 6 minutes of continuous data,
starting with ZRO level 8 data, (24 dB below the beacon)
including the level 9 (-27 dB) and level A (-30 dB)
signal, finishing with the "End of test" message
at full power. Recorded by Darrel AA7FV. |

#20437
(1990-005B) |
UoSAT OSCAR 14 was launched
together with UoSAT OSCAR 15 from Kourou on the Ariane
flight V35 ASAP into a sun-synchronous orbit (hight
780km, inclination 98 degree). The primary payload of
this Ariane launch was SPOT-2.
The primary purpose
UO-14, a 46kg 3-axis stabilized satellite, was a digital
Store and Forward communications transponder supporting
multiple access from hundreds of portable groundstations.
It was particularly suited to communications in remote
or disaster-stricken areas. Two experimental payloads
were included to monitor the radiation environment experienced
by the satellite in Low Earth Orbit (LEO), measuring
cosmic particles, and total radiation dose.
UoSAT-OSCAR14
spent its first 18 months in orbit operating as an amateur
store and forward satellite. In early 1992, all amateur
operations were moved from UO-14 to UoSAT-OSCAR 22.
UO-14 operations were then dedicated for use by VITA
(Volunteers In Technical Assistance) who used it for
sending and receiving messages escpecially medical data
transmissions in Africa (service was called also Satelife
and UO-14 was renamed to Healthsat-1). When the computer
used for store and forward communications became non-operational,
in March 2000 UO-14 was re-configured as a very popular
single channel FM repeater in space. Frequencies used
were:
Uplink: 145.975
MHz (9600 bps FSK AX.25) or analog FM
Downlink:
435.070 MHz (9600 bps FSK AX.25) or analog FM
Beacon:
435.070 MHz (1200 bps AFSK (NBFM)
AX.25)
UoSAT-3 was taken out of service in August
2003 due to insufficient power from the rechargeable
batteries which lost their capacity. |

UoSAT OSCAR 15 was launched
together with UoSAT OSCAR 14 from Kourou on the Ariane
flight V35 ASAP into a sun-synchronous orbit (hight
780km, inclination 98 degree). The primary payload of
this Ariane launch was SPOT-2.
The RF system on
UoSAT-4 consisted of three VHF receivers and two UHF
transmitters. During normal operation all receivers
were active and one downlink could be selected via a
telecommand operated relay. Up and down link data rates
were 1200 AFSK and 9600 FSK, though only 1200 AFSK was
used during the commissioning phase. The transmitter
output power was set to 1.5 watts during acquisition
could have be switched up to 5 Watts.
UoSAT-4 failed
30 hours after launch, thus most likely no recordings
of its transmissions are available.

#21087
(1991-006A) |
This satellite was a
joint venture between the AMSAT organizations in Russia
and Germany. The amateur equipment rode piggyback on
a Russian experimental geological satellite (INFORMATOR-1).
The joint project was called Radio M-1 by the Russian
team (amateur radio satellite club Orbita and the Adventure
Club of Moscow) respectively Rudak-2 by the German hams
(at Marburg, Munich and Hannover). The collaboration
led to dual names for the new amateur radio satellite
once it arrived in orbit: AMSAT-OSCAR-21 (AO-21) and
Radiosputnik-14 (RS-14).
AO-21 was a very successful
and popular satellite as the 4 different receiving channels
in the 70cm band supported multiple modes. The computer
could generate differently modulated signals (BPSK,
AFSK, FSK, RSM, FM) and thus eight different modes could
be transmitted:
- 1200 bps, BPSK, NRZI (Fuji mode)
- 400 bps, BPSK, Biphase s, (Phase-3 mode)
- 2400 bps, BPSK, Biphase s, (Rudak-1 mode)
- 4800

(1993-061C) |
EYESAT-1 was built by
AMRAD (Amateur Radio Research and Development Corporation).
It was one of six satellites that were launched together
on a Ariane V59 rocket from French Guiana. Once in orbit
and operational the amateur payload of EYESAT-1 was
designated AMRAD-OSCAR 27. AO-27 features a Mode V/U
(J) FM Voice Repeater. The uplink frequency of this
bent pipe FM repeater is 145.8500 MHz (FM), the downlink
frequency is 436.7950 MHz (FM). This satellite can be
worked with simple FM equipment and was also successfully
tested with D-Star. |

Telemetry recorded by Don Woodward, KD4APP, Nov 19th
2002 |
Usually
analog FM voice transmissions are used via AO-27. However
the new DSTAR standard which is intended to be used
via terrestrial FM repeaters can be also used via satellite
as the test transmission of Luc Leblanc VE2DWE demonstrates.
He used an ICOM IC2200 TRX for the 436.795 MHz downlink
and a ICOM ID-800H for the 145.850 MHz uplink. Recorded
on September 5th 2009 at 22:49
UTC and kindly provided by VE2DWE. |
After
16 years in orbit AO-27 was still operational. Enclosed
downlink signals on 436.797 MHz were recorded on March
14th 2010 at 12:21 UTC by DD1US

In memoriam
to the first man made satellite Sputnik-1, which was
successfully launched 40 years before, this little satellite
was launched by hand during an EVA (Extra Vehicular
walking in space) from the MIR space station. The RF
signal sounded like a beep-beep as the transmitter with
a power of 100 to 200 mW was keyed on/off. The RF carrier
on 145.820 MHz
was FM modulated and the frequency of the audio signal
varied with the temperature inside the satellite. Recorded
in FM on November 3rd 1997
12:45 UTC by IK1SLD. For confirming the reception by
a QSL card the award was given. |

On May
7th 2002 the U/K-band transponder
was used by Charles G3DWG and Mike N1JEZ for the first
transatlantic QSO with a joint 24GHz downlink. Please
note the rather low doppler shift due to the fact that
they used the transponder while AO40 was at apogee (distance
was about 61000 km). The output power of the K-band
transmitter was estimated to have dropped to about 600-800mW.
Recorded and kindly provided by Mike N1JEZ. |
On February
23rd 2003 the S1/K-band transponder
was tested. In enclosed recording of the 24 GHz downlink

Her are some very special
goodies. They were not recorded while AO40 was in orbit
but during the various integration tests and the final
prelaunch tests in Kourou.
The first
audio file is a test of the LEILA function in CW conducted
by OH2AUE during pre-launch tests.
The second
audio file is a test of the LEILA function in SSB conducted
also by OH2AUE in Kourou.
The third
audio file was a test of the built in microphone of
AO40 by DB2OS (tapping the support frame).
The forth
audio file was another test of the micro. You can hear
Peter DB2OS "talking to the bird".
The fifth
audio file was a test of the microphone already done
during one of the integration tests in Florida. All
three momentum wheels have achieved synch to the programmed
test values. Analyzing the audio spectrum with a PC
FFT program you can see the frequencies and thus calculate
the rotation speed of the wheels directly.
The sixth
audio file is the 400bd PSK beacon recorded during thermal
vacuum tests in Virginia.
 The seventh
audio file is also the 400bd PSK beacon received on
70cm band during tests on June 26th
1999. If you decode this file with the AO40RCV freeware
then you can decode 4 blocks of data which I enclose
also a s a text file.
This
is the last special from AO-40. You can decode this
audio file with the P3T software. The result is great
fun as you can see from the telemetry that all RF transmitters
are turned OFF, only the IR laser is turned ON. This
was probably the only time that the IR laser was ever
actually received and demodulated + decoded. The laser
was never tested in space. Michael OH2AUE made this
recording during the launch preparation and final tests
in Kourou.
All these recordings were kindly
provided by Michael Fletcher OH2AUE. |

(2009-038B) |
On July 30th
2009 the DRAGONSAT-2 (Dual RF Astrodynamic GPS Orbital
Navigator Satellite) project was released from Space
Shuttle Endeveaur (STS-127). It consists of 2 sister
satellites BEVO-1 and AGGIESAT-2. AGGIESAT´s downlink
frequency is 436.250 MHz and it uses a proprietary modem
protocol as the main radio is a COTS data modem. It
appears that the only way to decipher the code is to
have a model MHX425 that can speak the proprietary language.
The radio data rate is actually at 19200 bps. |
July
30th 2009 |
The audio
file of AGGIESAT-2 was recorded by Mike DK3WN on July
30th 2009 at 16:04 UTC during
the 2nd orbit of AGGIESAT-2. |

BEVO-1 was deployed together
with its sister satellite AGGIESAT-2 from Space Shuttle
mission 127 on July 30th 2009
at 12:34:50 UTC as part of the DRAGONSAT program. It
is a picosat mission of the University of Texas to test
a GPS unit designed and built by NASA. Texas A&M
and the University of Texas were required to build 5"
cubesat spacecraft buses and support systems for the
GPS units.

July
30th 2009 |
Status as of August 5th
2009: Still no signals from BEVO1, although beacon packets
were heard from AGGIESAT2. The current theory on the
state of the satellites is that only partial separation
occurred. The inhibit switches keeping the satellites
powered off have been closed, allowing the satellites
to boot up. However, it is likely that the antennas
did not deploy correctly, leaving the antennas disconnected
from their respective transmitters. AGGIESAT2 transmits
with 1W of power so it is easier to hear, while BEVO1
only transmits with 200mW during beacon mode. |
Unfortunately the 2 satellites
did not separate after they were released from the space
shuttle you will find only one single set of Keplerian
elements referred to as "DRAGONSAT". On the
left you can also see 2 pictures where AGGIESAT-2 (top)
and BEVO-1 (bottom) are shown still attached to each
other after launch. |

On July
30th 2009 the ANDE-2 project
was released from Space Shuttle Endeveaur (STS-127).
It consists of 2 satellites called Castor and Pollux.
Pollux-1 transmits every 33 seconds a telemetry
packet on 145.825 MHz in FM/AFSK using 1200bd with F.25
(FEC) on top of AX.25. It also has the possibility to
transmit 9600bd packet radio signals and test GMSK modulation.
Pollux´s transmit frequency is about 1.5 to 2
khz higher than Castor´s. Furthermore the signal
of Pollux is stronger than Castor´s signal in
spite of the fact that they should use the same transmit
power of up to 1W. Enclosed audiofile which contains
signals from Castor and Pollux was recorded by Mike
DK3WN during orbit no.1 on July 30th

(2011-xxx) |
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 30th 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 12th
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 16th
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. |

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.

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 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 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). |
