The Proposed GBDC Planning Cycle
We will receive data from the Cluster Joint Science Operations Centre (JSOC)
once a week. From this we will compile the list of
"events" which are the basis
of the predictions you will receive from us via these pages. We will receive
five classes of orbit and operations predictions for any date and UT (time t).
The first three are to allow us to make input to the Cluster SWT/JSOC planning:
- T - Pre-launch test scenario data (code T for test)
- I - Initial plans at t-6 months (code I for initial)
- R - Refined plans at t-4 months (code R for refined)
For information and to allow us to refine our plans, we will also give
- A - Approved plans from SWT at t-2.5 months (code A for
approved)
- F - Final plans (A-plans as implemented by JSOC)
at t-2 weeks (code F for final)
In addition, we hope to arrange a sixth classification with JSOC:
- P - Post-observations data at t+1 month (code P for Post)
For any one configuration with your ground observatory site, the predictions
given will always be the most up to date, and will carry the T, I, R, A, F, or
P status flag. For each event listed there will be a further classification
according to the data-taking plans of JSOC:
- Y - Data recording is planned (code Y for yes)
- N - No data recording is planned (code N for no)
We will also convey information from the JSOC on satellite separations and
configurations, instrument modes and the planned start and end times of each
data taking period.
The predictions pages will offer you the chance to log your plans, which will
be used by your representative, Hermann Opgenoorth, at Cluster Science Team
(SWT) meetings to try, wherever possible, to prevent plans you find favourable
from being changed. They will also automatically be passed on to JSOC and
displayed on these WWW pages. These pages will also offer you an opportunity to
log any important events for which you find the plans are unfavourable and we
can then request the SWT to change them accordingly.
To have a realistic chance
of influencing an unfavourable plan and to ensure that a favourable plan is not
changed, your input would be needed before t-3 months.
The earlier you let us know, the more chance there is to accommodate your plans
with SWT's and JSOC's.
If you foresee problems with these draft arrangements with JSOC, please
let us know now
