Mir Status Dec 7, 1998





Mir Amateur Radio Status:  Dec 7, 1998

by Miles Mann WF1F,
MAREX-NA (Manned Amateur Radio Experiment, North American Division)


Mir School Schedules:
The Mir crew has had some free time to run a Pre-arranged School schedules
to celebrate
the 10 year anniversary of Amateur Radio Access from the Russian Mir Space
Station.
As time permits the MAREX-NA team runs school schedules with the crews on
Mir.
All schedules are arranged months in advance with the engineers at Energia
in Russia.

Last weekend we ran a school schedule with in North Yorkshire England, at
the Harrogate Ladies College.  Seven students were able to ask the Mir crew
over 14 questions.
The school received a temporary  Third-Party traffic waver and were allowed
to have
a few non-licensed Russian students conduct part of the radio schedule in
Russian.
The crew enjoyed the schedule so much, they came back for seconds on the
next pass.  The
students had over 16 minutes of two-way contact with the Mir crew Sergei
Avdeyev and  Gennadiy Padalko.

Future Schedules:
Over the next few months school schedules with Mir are planned with the
following countries,
USA, Canada and Australia.  Due to the limited volunteer staff of MAREX-NA
and that we do not have a budget, were are not actively looking for new
schools.  We have a large back log of
existing schools, enough to keep us busy for the rest of the year (1999).
MAREX-NA has been running school schedules with Mir since September 1991,
and has participated in over 70 Mir school schedules world wide and more
are planned
for the future.

Third Party Traffic:
At the present time the laws of the USA and other countries severely limits
access to the Mir station and ISS.  Most countries will only allows a
licensed ground station to talk to another
licensed station.  We can only hope that the laws will be updated to allow
licensed control operators to handle Third-Party-Traffic with ISS and Mir
in the future.


PMS is off Line (Temporarily)
The Mir Personal Message System went off line Saturday Nov 29, 1998 and was
still
off line as of Dec 1.  I have been in contact with Energia and was have
been discussing
the problem.  The PMS is just sending a Beacon, and is not responding to
connect requests.
We have seen this problem twice before and it may be related to a
Overflowed serial buffer
in the KPC-9612.  The overflow is caused when the crew disconnects the PC
for several days.
Data coming into the TNC from the radio gets stuck trying to go out the PC
port.
Since the PC is not connected, the data backs up.
A simple power cycle or soft reset should clear the problem.
Instructions will be sent to the Mir crew over the commercial channel this
week.


Tracking Mir, Sputnik and Zarya

The best way to track satellites is to get access to a good satellite
tracking program.  There are numerous programs on the market, both for sale
and share ware.

The orbit of Mir is drifting much faster this year than last year.  Mir is
now 30 miles lower than
it was the same time last year.  The lower the altitude, the greater the
drag.
The drift is so great that week old KEPS may be in error by 4 minutes.  If
you want to track Mir,
you will need to update your KEPS at least weekly.
Unmanned Satellites in higher orbits do not need frequent KEP updates.  As
a general rule, the higher the orbit the longer your KEPS will be good for.
Example Oscar 10, keps are good for  30-60 days.
