Planetary Missions Division Dvk, 16 Jul 2002 Interfaces - presented at the SWT #10 To clarify the situation with interfaces, formats, etc. Summary: There are three different interfaces, but we now all speak the same language (ITL). Detlef Koschny and the Science Operations Team Research and Scientific Support Department ESA/ESTEC

Planetary Missions Division Dvk, 16 Jul 2002 Interfaces vs. project phase On test floor  responsible is Alenia  uses CCS (Central Checkout System)  Syntax of operational files: ELISA During commissioning phase  ESOC is responsible  Uses MOIS (Mission Operation Information System), based on Microsoft products (Excel, Visio, …)  Operations will be done using interactive approach, “paper” procedure required called Flight Control Procedures (FCPs) – inputs from experimenters previously collected via paper  ESOC collects inputs for database (Telecommands, TCs) During nominal science operations  Only interface is RSOC  Operations is done with TC sequences (a sequence of TCs that is triggered from the Mission Timeline (MTL) – does not allow telemetry checks)  Uses Experiment Planning System (EPS), takes ITL syntax

Planetary Missions Division Dvk, 16 Jul 2002 Interfaces vs. project phase The only complication…  There will be a transition phase between FCPs and TC sequences after commissioning  Already in the commissioning phase we have two scenarios where the Science Operations Team is coordinating: Pointing and Interference Scenario The good news:  There is a converter from ITL to ELISA  ESOC will accept all new input in ITL syntax ITL syntax – some background  ASCII files in a syntax that allows to specify Operational Requests (OIORs), Telecommand Sequence definitions (CS), Flight Control Procedures (FCPs) including TM checks and special instructions to operators.  Really should be called ITL/EDF syntax…  Information on how to provide the info was sent out to at least everybody on my list on the operational responsible – documented on our livelink server: Rosetta/Tools/EPS/User Manual (incl. Templates)

Planetary Missions Division Dvk, 16 Jul 2002 Interfaces – Test floor Experiment Alenia team/ CCS ELISA files Old: ELISA Converter New: ITL ELISA CCS: Central Checkout System ELISA: File syntax for CCS ITL: Input Timeline, file syntax for RSOC software

Planetary Missions Division Dvk, 16 Jul 2002 Interfaces – Commissioning Experiment RMOC SCOS 2000, MOIS Flight Control Procedures Old: Paper input for FCPs Converter Now: ITL Excel + paper FCPs: Flight Control Procedures (paper procs used for operations by ESOC RMOC: Rosetta Mission Operations Centre SCOS: Spacecraft Operating System – used by ESOC to operate Rosetta MOIS: Used by ESOC to produce FCPs and Telecommand Sequences

Planetary Missions Division Dvk, 16 Jul 2002 Interfaces – Science Operations Experiment RMOC SCOS 2000, MOIS TC sequence calls OIOR (ITL syntax) POR RSOC EPS, PTB Also used in Pointing and Interference Scenario during Commissioning Phase CS updates (ITL syntax) CS updates (Excel) OIOR: Orbiter Instrument Operations Request ITL: Input Timeline (file syntax used by RSOC) RSOC: Rosetta Science Operations Centre EPS: Experiment Planning System – planning software used by RSOC PTB: Project Test Bed – environmental simulator used by RSOC POR: Payload Operations Request – file syntax used from RSOC to RMOC CS: Telecommand Sequence
