Latest News From AMSAT - UK
AMSAT-UK have been informed by SSTL that UO-22 is not in good shape, and
its looks as though its useful life may be over. The SSTL Ground Station
control centre at the University of Surrey have attempted several times
in recent weeks to reactivate the satellite.
After one attempt it did come back to life, but only briefly. Other
attempts have failed completely. As time permitts, the Control Station
may make further attempts at reactivation, but it seems unlikely that
they will be completely successful.
The cause if the satellite's demise is unknown, but may be related to
the batteries which have been in space for more than 10 years, or to the
fact that the satellite is very hot due to the orbit preccessing such
that it is generall in full sunlight. The elevated temparature was
causing problems with the receivers, as well as the battery.
UO-22 was laaunched in July 1991 from Kourou, French Guiana, and served
for many years as the store and forward satellite for the Amateur Radio
Packet Radio world wide SatGate service, which linked packet radio
networks in many countries.
