**** UoSAT Bulletin-106 (Edited) 4th January 1985 ****
UoSAT Spacecraft Control Centre, University of Surrey, England
** GENERAL NEWS **
A H A P P Y and P R O S P E R O U S N E W Y E A R
to all UoSAT Experimenters - worldwide - from the UoSAT Team.
* UoSAT Opportunities at UoS *
There are opportunities for Research Fellows, Assistants and
Technicians to work on the UoSAT Spacecraft Programme at UoS
supported by grants commencing immediately. Details of
responsibilities and requisite qualifications will appear in
next Bulletin.
* Bulletin Information Sources *
The generation and editing of the weekly UoSAT Bulletin is a
considerable task for the small team at UoS and therefore we
welcome contributions from all sources providing the content is
of general interest to satellite users/experimenters. Much
general news is gleaned from ASR and other sources worldwide
via Telemail. Due to the limited space available for the
UoSAT-1 Bulletin, this information is generally edited and
condensed and it is not always possible to acknowledge the
source in detail. It is quite a problem to 'shoe-horn' the
Bulletin to fit efficiently into the OBC memory - we regularly
have just ONE byte spare! So you can see that, at times, every
letter/space etc counts! We are, however, very grateful for
the information passed to us and we hope that the UoSAT User
Community finds the service and content interesting & useful.
* UoSAT-OSCAR-11 Stabilisation *
Automatic attitude control manoeuvres, carried out by the OBC,
successfully restored gravity-gradient stabilisation to UO-11
after inadvertant destabilision last November - all is OK.
* NOAA-9 *
NOAA-9 was launched at 10:42 gmt on 12 December and is
scheduled to enter service on 1st February 1985.
** UoSAT-Oscar-9 Schedule **
The UoSAT-1 Experiment Schedule will change from 110185 to
reflect majority interests of the user community derived from
an analysis of the many reports and suggestions received during
1984. It is, of course, not possible to please everyone and
some of the suggestions would necessitate a great deal of
software development which we cannot, at present, support - but
we hope that the new schedule will meet with general approval.
Comments are welcome however!
The new schedule will be as follows:
Friday - load Bulletin
Saturday - Bulletin/1200 bps telemetry
Sunday - Bulletin/1200 bps telemetry
Monday - DIGITALKER/1200 bps telemetry
Tuesday - Radiation data - next week CCD data
Wednesday - Computer check-summed telemetry
Thursday - Whole orbit telemetry survey
This weeks schedule is as follows:
Friday - load Bulletin
Saturday - Bulletin/DIGITALKER/1200 bps telemetry
Sunday - Bulletin/DIGITALKER/1200 bps telemetry
Monday - Bulletin/DIGITALKER/1200 bps telemetry
Tuesday - CCD Camera - next week Radiation data
Wednesday - Whole orbit telemetry survey
Thursday - Computer check-summed telemetry
The 21 MHz Beacon will be in use this week.
