ISSのパケットに関する、Frankからの続報です。

All,

As I stated yesterday, We will continue to keep you informed on the
on-going, drawn-out saga on the packet system.

  Well, it should be obvious at this point that the packet is still not
working.  The procedure we (US and Russian teams) generated did not get
uplinked to the crew.  Our plans were to have a one-on-one discussion with
Ed Lu around 13:00 UTC today as he debugged the packet module issue.  We
got word right before the pass that the radiogram did not get
uplinked.  Despite this, several U.S. ground stations still attempted to
contact ISS with no success.

The ARISS team plans to have another international teleconference tomorrow
with NASA in attendance to scope out our recovery plan.  Tentatively, we
are going to ask (again) for the crew to turn on and re-configure the
packet module.  To ensure this gets done before Expedition 8 (yes...before
November) we are asking that the crew perform the procedures without an
audio debug session.  This may occur as early as this weekend.

Over the past few months I have had numerous discussions with NASA senior
management about our inability to get our packet procedures uplinked to ISS
and performed by the crew.  Many of these individuals are painfully aware
of our problem and have agreed to work with us to resolve this
problem.  FYI, we had a similar problem with school group operations at one
point and we resolved these problems similarly.

What complicates the non-school group operations process is that both the
US and Russian operations teams need to be fully cognizant of our plans and
agree to them in a timely fashion.  Crew members on both sides are involved
since the equipment is in the Russian segment and a US crew member is
usually doing the debugging.  Unfortunately, something seems to go wrong
along the way and we end up having to start over.

I know many of you are frustrated.  We are too.  Please do me a favor and
do not compare our ISS ops to the Shuttle operations or Mir
operations.  The ISS is a relatively new vehicle and international
operations is definitely not simpler than US-only or Russian-only
operations.

Please remember too that there are only 2 crew members on ISS when there
are usually 3 members.  So the level of work that this expedition is
experiencing is much higher than normal.  Thus, our ability to request crew
member's time on the Russian or US side is very difficult.

When you look at operations and realize that hardware development has had
nearly the same hurdles to overcome, I think you can imagine the
substantial challenges and near miracles that were required by the ARISS
team to bring the ISS amateur radio hardware to fruition.  I am proud of
this international team.  Further, I am convinced we will resolve this
process problem and move on to other challenges...including the
installation of the Phase 2 hardware in a couple of months.

Please keep the faith.  We promise to continue to keep you informed as
events unfold on the packet issue.
