Ignacio Tanco| SWT#08, ESAC| 2016/01/26 | Slide 4 ESA UNCLASSIFIED – For Official Use OPS-OP - Solar and Planetary Missions Division Flight Operations Concept: Commanding  Routine Instrument operations will be off-line. No real-time commanding. o Instrument commanding prepared in advance. o Operations built in atomic sequences, uplinked as safe end-to-end activities. These activity cycles will speed up return to science. o At the boundaries of the activity cycles are the so-called re-entry points. o Instrument User Manuals must define operations in terms of sequences: o In-situ example:  Default Mode -> Adjust operational parameters -> Command Mode X -> Return to Default o Remote Sensing example:  Switch ON -> Warm up detector -> Adjust operational parameters -> Command Mode X -> Go back to Stand-by

Ignacio Tanco| SWT#08, ESAC| 2016/01/26 | Slide 5 ESA UNCLASSIFIED – For Official Use OPS-OP - Solar and Planetary Missions Division Flight Operations Concept: Telemetry  Only TM going into the OBC can and will be monitored – Both on-board and on Ground. You should route: o All TC Acknowledges (S1). o Relevant HK TM for Ground and FDIR monitoring (S3). o All Events (S5). o All Dumps (S6). o All ping responses (S17). o Any private report worth monitoring.  This data stream cannot exceed 500 bps (essential HK TM).  Bonus: All HK TM S(3,25) packet must be of fixed length.

Ignacio Tanco| SWT#08, ESAC| 2016/01/26 | Slide 6 ESA UNCLASSIFIED – For Official Use OPS-OP - Solar and Planetary Missions Division Baseline Instrument FDIR  Baseline FDIR is no autonomous return to Operations: o Instrument contingency -> Suspend operations -> Recovery by Ground o Monitoring performed on HKTM ‘heartbeat’  An extension of this baseline is considered feasible.

Ignacio Tanco| SWT#08, ESAC| 2016/01/26 | Slide 8 ESA UNCLASSIFIED – For Official Use OPS-OP - Solar and Planetary Missions Division Conclusions and Recommendations  Instrument Teams must start to develop their Instrument Procedures ASAP.  ESOC will be ready to start coding them into sequences as of 2 nd half of  TO DO : o Think about your Operational Concept in terms of activity cycles! o Develop the necessary procedures to support your activity cycle. o Code the procedures in your User Manual. o Submit your updated User Manual to ESOC for coding into sequences.  Don’t Forget! o Procedures must also contain the TM checks required by Ground. o Ideally Commissioning should be run with Routine procedures!
