ARISS Contingency Network Activated

October 30, 2006

On Thursday, October 26, NASA Johnson Space Center asked that the ARISS
Ops Team enable its ISS Ham Contingency Network and go into standby mode
as a resource for NASA. ARISS volunteers immediately swung into action.

Russian Flight Controllers were experiencing difficulties completing the
docking of a Russian Progress cargo vehicle.  Its antenna would not
retract properly as it neared the ISS.  It is a requirement for the
antenna to be retracted before the last step of the physical docking is
executed to avoid a collision between the antenna and the docking port.
  The ISS was put into a free-drifting mode, which aids the crew with
docking maneuvers.  Free-drifting results in the ISS solar arrays not
being pointed directly toward the sun.  This causes decreased power
generation for the ISS, and the crew is required to slow down or shut
down some ISS systems to conserve power.

During free-drift mode, a loss of TDRSS (Tracking and Data Relay
Satellite System) coverage can occur; TDRSS is the system that handles
communications between astronauts and Mission Control (MCC) in Houston.
  The ARISS Team was asked to ready its ISS Ham Contingency Network so
that MCC could feel secure in having solid communication coverage while
their staff took care of the docking issue.

The docking problem was solved, and the ARISS contingency network wasn't
used by NASA for actual communications.  NASA's request and the ensuing
ham activity served as a great drill for the ARISS Team.  MCC (Houston)
was impressed with how quickly the ARISS Team had its system up and
running.  The MCC staff's concern about the possible TDRSS problem was
lessened, knowing of the hams' ability to act as a back-up resource in
the case that it is ever needed.

Kenneth Ransom, N5VHO, generated a procedure for the ISS crew on the
operations of the ARISS contingency network. The fact that the ARISS
Team was asked to be on standby was known by anyone listening to the
NASA communications channel. MCC Houston transmitted a message to the
crew that information would be uplinked about the ham network and the
procedure for it if they needed to invoke it.

It was the first time in the six-year history of ARISS that NASA had
asked the hams to bring up the contingency network. Within 15 minutes of
receiving the call from NASA, ARISS Ops Team member Kenneth Ransom,
N5VHO, reported the ARISS Ops Team ready to communicate.  ARISS Team
member Tony Hutchinson, VK5ZAI, of Australia, was awakened at 2 AM, and
got on-line to make a blind call up to the crew, although they did not
need to answer at that point.

Within the 3.5 hours from the time the initial phone call came, until
the team got word to shut down, Tony Hutchison, VK5ZAI, was as his mike,
and these additional stations were on standby to cover later passes:
Gerald Klatzko, ZS6BTD, in South Africa; Gaston Bertels, ON4WF, at the
Belgian ON4ISS station; Dick Flagg, AH6NM, and Nancy Rochelau, WH6PN, at
Sacred Hearts Academy in Honolulu, Hawaii; and Frank Bauer, KA3HDO, and
Mark Steiner, K3MS, at the Goddard Space Flight Center ham station,
WA3NAN.  The ARISS teamwork was very effective; its members learned a
great deal, and they impressed NASA with how quickly the system was
brought up.

                     31 October 2006

OSCAR-11 is back!  It was first heard by Peter ZL3TC, at 06:23 UTC on
October 18. It had been silent since August 26.

During the period 28 September to 30 October, the satellite was heard
from 18 to 28 October. Good signals have been heard on most passes, often
very strong.

Further deterioration of the time/date stamp has occurred.  Here is a
frame of telemetry captured on 27 October at 08:43:51 UTC.

UOSAT-2           060=601033448


The date/time stamp is the block of characters following 'UOSAT-2' having
the format YYMMDDWHHMMSS (Year, month, day, day of week, hours, minutes,

The month, shown as '0=' in the date stamp is now in all telemetry
frames. When the satellite was heard in August the month, had stuck at
07 and the day had incremented to 60. During the ten day reception
period in October, the day had correctly incremented from 51 to 60.
While the satellite was silent, it appears likely that the day may have
incremented to 99 and then reset to zero.  It will be interesting verify
this theory on future passes.

During the last ten days of beacon transmission the time stamp
incremented accurately, and no gain or loss was detected ( within one or
two seconds).  However, on one occasion, the most significant digit of
the hours failed to change from zero to one, although it didn't  cause a
permanent error.

If the satellite continues to operate normally, the beacon should switch
ON around 07 November. If nothing is heard, it may be worth listening
ten days later, ie. around 17 November.

I am indebted  Peter ZL3TC, Bob G4VRC, Paul KB5M, and Doug KA2UPW/5 for
their reports and for monitoring the satellite. Peter listened for the
satellite daily, often during several passes, while it was silent.  Many

The status of the satellite, when last heard, was that all the analogue
telemetry channels, 0 to 59 are zero, ie they have failed. The status
channels 60 to 67 were still working. The spacecraft computer and active
attitude control system have switched OFF, ie. the satellite' attitude
is controlled only by the passive gravity boom gradient, and the
satellite is free to spin at any speed. When telemetry was last received
it showed that one of the solar arrays had failed, and there was a large
unexplained current drain on the main 14 volt bus. After 22 years in
orbit the battery has undergone around 100,000 partial charge/discharge
cycles, and observations suggest that it cannot power the satellite
during eclipses, or sometimes during periods of poor solar attitude.

The watchdog timer now operates on a 20 day cycle. The ON/OFF times have
tended to be very consistent. The average of many observations show this
to be 20.7 days, ie. 10.3 days ON followed by 10.4 days OFF. However,
poor solar attitude may result may result in a low 14 volt line supply,
which may cause the beacon to switch OFF prematurely, and reset the
watchdog timer cycle. When this occurs, the beacon is OFF for 20.7 days.

The Beacon frequencies are -

VHF 145.826 MHz.  AFSK FM  ASCII Telemetry

UHF 435.025 MHz.  OFF

S-band 2401.5 MHz. OFF

Listeners to OSCAR-11 may be interested in visiting my website. If you
need to know what OSCAR-11 should sound like, there is a short audio
clip for you to hear. The website contains an archive of news &
telemetry data. It also contains details about using a soundcard or
hardware demodulators for data capture.  There is software for capturing
data, and decoding ASCII telemetry.  The URL is

LA/W5ACM will be active on board a cruise ship in the Caribbean Sea
starting on October 30, 2006. Ports of call include Jamaica, Grand
Cayman and Cozumel.  NO operation will be attemped from land, but
many grids will be made available while at sea.

Target satellites include SO-50 and AO-51. Due to the difficulty of
SSB up/FM down ops via AO-51, better results are expected via SO-50.
We will give it our best shot! QSL to Andy's W5ACM home call.

Other satellite ops on this cruise include WB5RMA, WA5TWT, WA5WOD and

Bob, K0NR will be active as PJ4/K0NR from Bonaire (IOTA SA-006) from
Oct 28 to Nov 9th, SSB and PSK31 on 30M through 6M. Also active on FM
OSCAR satellites (Grid FK52). QSL to K0NR home call.

Nader has ended his ST2NH operation from Sudan and returned home to
Saudi Arabia where he plans to be active again from El Rijadh as HZ1NH
on the satellites.  During his three weeks in Sudan he reported working
23 countries and made 105 QSOs with different stations mostly in Europe
using AO-7, FO-29, AO-51 and AO-52.
