Dick Daniels, W4PUJ Memorial Service Video Posted

Bob McGwier, N4HY has posted a video of the February 25 memorial service
attended by family, friends, and colleagues for AMSAT's Dick Daniels,
W4PUJ who passed away on February 14, 2012:

http://youtu.be/pGhn1eC52Wo

AMSAT President Barry Baines, WD4ASW read excerpts from the obituary
written by Jan King, W3GEY/VK4GEY and included personal comments of his
experience knowing Dick and working with him. The text of Dick's
obituary is posted on the AMSAT web at:
http://tinyurl.com/W4PUJ-Obituary.

Barry observed in his comments at the memorial service that NASA
announced AMSAT Fox-1 satellite's acceptance into their ELaNa launch
program on February 14, the day Dick passed away. Dick's legacy for
amateur radio in space will continue.

Bob recalled, "Dick was always supportive and helpful to me and like all
who knew him, understand the size of our loss. Dick was the epitome of
solidarity, always honoring his obligations, with a big sense of
responsibility with no obvious sense of entitlement to anyone's thanks.
Dick was always seemingly asking himself 'what have I done for you
lately?' We've lost the irreplaceable."

Eric Rosenberg, W3DQ wrote of his memories of Dick, "He was a great guy,
wonderful to work with, both professionally and within AMSAT.
He was treasure trove of information and defined corporate knowledge and
memory. His collection of Oscar 10 telemetry on those hard sectored
disks was legendary around here, but not as much as his pool table, upon
which many of the early satellites were put together."

Bob, N4HY took a collection of photographs with his phone camera which
has added to his online album:

COMPASS-1 Satellite End of Mission

The COMPASS-1 CubeSat was designed and built by students from the
Aachen University of Applied Sciences in Aachen, Germany. It has
been in orbit since its launch from India on April 28, 2008.

This week Mike Rupprecht, DK3WN reported on his DK3WN SatBlog that
on Saturday, February 25 a single beacon was received. COMPASS-1
underwent a complete restart and the thresholds for heater and bat-
tery voltages were set to new levels. Battery temperatures tracked
with the received telemetry data have shown some very cold spikes.
This may be affecting operation of the satellite.

On March 3, Mike received the following message from Professor
Dr. Bernd Dachwald, Faculty of Aerospace Engineering FH Aachen at
the University of Applied Sciences:

  Dear supporters and friends of our COMPASS-1 mission,

  First, let me thank you very much for your support in trying to
  save the life of our COMPASS-1 satellite during the last days,
  but also during the last years of "routine" operations.

  It seems that our mission now comes to an end. The projected life-
  time of COMPASS-1 was half a year. The tiny guy has outperformed
  this value by a factor of more than seven. April 28th would have
  been its 4th birthday and if it was a human, it would now be
  about 500 years old (Cubesat-years are short).

  So, if you have more important things to do (and I guess so), we
  cannot expect you to continue your efforts in saving its live.
  With your support, you have made things possible that we would
  never have been able to achieve with our own resources and I
  appreciate your support very much.

  So, COMPASS-1, rest in peace. (Nevertheless, if you still want
  to try to awake it from the dead, feel free to do so.)

  I hope that we will soon be able to build and launch COMPASS-2
  and that you will be still available, all over the world, as a
  ground station to command and fly our new bird. We will keep
  you informed.

  Cheers and thanks for all,
  Bernd

Operators may periodically listen for the COMPASS-1 CW beacon on
437.275 MHz CW beacon every 3 minutes. Any reports are very
appreciated.

The DK3WN SatBlog tracked monitoring and attempts at recovery
over the past week:

+ On Sunday, February 26 no signals were heard from COMPASS-1
+ On Monday, February 27 no signals were heard; Several attempts to
  reset the satellite were unsuccessful.
+ On Tuesday, February 28 first report received after nothing heard
  for two days. Decoded telemetry showed the satellite had reset.
  Control stations reset voltage and heater thresholds to conserve
  power:

  Power Level             Critical Battery Capacity
  Heater Active           Battery Heater ON
  Power Safe Counter      0       <=== Counters reset to 0
  Emergency Mode Counter  0
  Battery Voltage         2.82 V
  Battery Current         0.00 mA
  Battery Temperature     0 °C    <==== Battery temperature COLD!

  The usual operational threshold is for the heater to be on if the
  temperature inside goes under 10 deg. The batteries are weak and
  this has caused COMPASS-1 crash.

+ On Wednesday, February 29 Alan, ZL2BX could command COMPASS at
  19:25 UTC - all thresholds commands were accepted. COMPASS went
  into eclipse at 19:45 and into sunlight at 20:17 UTC. DK3WN set
  the thresholds at 20:20 UTC and got an confirmation beep for all
  commands. COMPASS is now in Emergency Mode and the beacon inter-
  val is 8 minutes. The heater is OFF which will help improve the
  voltage problem. Since all counters are zero it is assumed that
  COMPASS resets in every eclipse. Not sure if the threshold values
  are kept after reset during eclipse.

  Power Level             Critical Battery Capacity
  Heater Active           Battery Heater OFF <== Command worked!
  Power Safe Counter      0       <=== Counters still reset to 0
  Emergency Mode Counter  0
  Battery Voltage         2.82 V
  Battery Current         0.00 mA
  Battery Temperature     3 °C    <==== Battery warming up
  (refer to: http://www.dk3wn.info/p/?p=26334)

Please continue to monitor 437.275 MHz for the COMPASS-1 CW beacon.
Current status can be read on-line on the DK3WN SatBlog at:
http://www.dk3wn.info

Mike has written telemetry decoders for several satellites, including
COMPASS-1. These may be found at: http://www.dk3wn.info/software.shtml

VO-52 Not Heard

Reports have been posted that India's VO-52 HAMSAT satellite, launched
on May 5, 2005 from India, has not been heard during expected passes
since February 28.

Summaries from stations monitoring for VO-52 cam be viewed at:
http://oscar.dcarr.org/

AMSAT INDIA Secretary Nitin, VU3TYG, posted on February 29 their last
known status, "We are aware of the current situation. Myself and Mani,
VU2WMY tried listening to the beacon and work thru the satellite during
the 04:05 UTC pass over India but nothing was heard."

Nitin will post further updates when more news is available from ISRO.
Amateur satellite operators are encouraged to post VO-52 status on

Antares Launch Slip Delays Dove-1 Satellite
http://www.uk.amsat.org/5061

The 3U amateur radio satellite Dove-1 (145.825 MHz AX.25 FM) was
originally planned to launch on the Antares launcher on February 28 but
reports indicate it may be Fall before it is launched.

Space.com reports that on February 21 Orbital Sciences Corporation
announced a further slip and the launch of Antares could now be delayed
until as late as September. Read the space.com report at:
http://tinyurl.com/Antares-Delay (space.com)

The new Dove-1 (DO-17 was the original Dove satellite) will transmit on
145.825 MHz 1200 bps AFSK AX.25 FM downlink with telemetry data,
including temp/power supply/current/RSSI/solar vector/acceleration,
approximately every 30 seconds. The beacon can transmit at up to 1 watt
and will use a quarter wave monopole antenna cut from a tape measure.

It also has a 2.4 GHz half-duplex, spread spectrum radio with patch
antenna that will be used for main payload downlink and telecommand
uplink. The data rate will be 115 kbps.

The planned orbit is 280 by 270 km at 51.6 deg inclination which will
give Dove-1 a lifetime of about 2 weeks before re-entry.

FITSAT-1 CubeSat to use 5.8 GHz and Optical Comms
http://www.uk.amsat.org/2037

The Amateur Radio CubeSat FITSAT-1 plans to transmit 115.2 kbps digital
data in the Amateur Satellite Service 5.8 GHz band and will also carry
an Optical Communications experiment.

FITSAT-1 (aka NIWAKA) is a 1U CubeSat (10*10*10cm) that should be be
deployed from the International Space Station by robot arm in late 2012.
It will generate about 2W RF output using a 16W DC input.

The main mission will be to demonstrate high speed data transfer from a
satellite, it can transmit a VGA-size (640×480 pixel) JPEG photograph in
only 5 to 6 seconds.

The second mission is to determine if a satellite can be made to appear
as an “artificial star” using high-output LEDs in flash mode.
The light from this flash will be received by the ground station, which
has a telescope with photo-multiplier linked to a 5.8GHz parabola
antenna. This is a basic experiment to investigate the possibility of
optical communication with satellites.

A UHF AX25 1k2baud transceiver will be carried for telemetry and
telecommand purposes and a UHF CW beacon will also be provided. It will
be deployed along with the satellites RAIKO and WEWISH into a 350x350km
51.6deg inclination orbit.

The following downlink frequencies have been coordinated by the IARU
Satellite Frequency Coordination Panel: CW 437.250 MHz, FM 437.445 MHz,
High speed data 5840.00 MHz.

Euroluna OZ9LUNA CubeSat Launch Update
http://www.uk.amsat.org/5153

Euroluna are a Danish amateur team participating in the $30 million
Google Lunar X PRIZE contest to be the first privately funded team to
land and drive a rover on the Moon. The President of Euroluna, Palle
Haastrup OZ1HIA gives an update on the Romit1 CubeSat and plans for
Romit2 and Romit3.

Romit1 is a 2U CubeSat that is planned to launch on the Interorbital
Systems Neptune 9 rocket. After deployment Romit-1 will stabilize itself
prior starting its engine to power itself into a higher orbit.
If everything goes well it should, after a year, be out in a 700 km
orbit, having started in a 310 km orbit.

It is hoped that radio amateurs across the world will assist the team in
retrieving the data sent down, for example, they can gather images from
the six cameras. The downlink frequency is 437.505 MHz at 1200bps.

The group are currently looking for a launch opportunity for Romit2 as
well as Romit3 that is planned to reach the Moon.
