  1. Unified Synoptics System Preparation and Operational Use of Synoptic Displays with the Unified Synoptic System – USS

  2. Overview • Developed within the Columbus project for replacing the existing legacy solutions in order to unify the different synoptic displays (a.k.a. synoptics) used on-board ISS and on-ground. • Free of charge for all ESA projects. • Import of different synoptics formats is provided. • Delivers large library of elements and symbols can be extended by import of graphical vector and bitmap data. • Elements with more complex dynamic behaviour can be developed in Java programming language. • Open interfaces (CORBA, XML) • Command and measurement handling adoptable to user/project needs • USS allows for reduced effort for: • synoptic preparation • synoptic verification • test & operational use • maintenance Uwe.Brauer@space.eads.net

  3. Architecture • Written in 100% pure Java and can therefore run on all platforms for which Java support is available • Installed and tested under Linux, Solaris and MS Windows XP, but should work on other platforms as well • USS consists of • USS shared components library (implements the USS domain model and the Java user interface panel) • On top of this library the two user applications (USS Editor and USS Executor) are developed • Uses a large set of open source libraries and selected commercial libraries (commercial libraries do not imply any runtime license costs for USS) • Full source code for the overall system is available to ensure future maintenance of the product for at least 10 years in the Columbus project Uwe.Brauer@space.eads.net

  4. Synoptic Preparation • State-of-the-art user interface similar to well known office and drawing tools like MS Visio. • Editor works online on the Columbus mission database or standalone on a file system. • System configuration data is accessed via a specific XML format • Drag and Drop from system configuration browser: • Display author can select one or multiple measurements and drop it on a display. • For every data field a name label and the according unit label are created from one of the measurement names. • Name labels are bound to the data fields and can be automatically updated if the system configuration changes.

  5. USS EditorEditing some synoptics (mimic displays) Uwe.Brauer@space.eads.net

  6. Automatic verification can be performed with the build- in consistency checker. Checks a single display or a set of displays according to a certain system configuration version and operational nomenclature standards (e.g. spelling, allowed acronyms and abbreviations). After the check a report is generated showing every consistency violation and the list of checked synoptics. Synoptic Verification Uwe.Brauer@space.eads.net

  7. Synoptics HTML Report for desktop review • Manual verification of displays can additionally be performed by using the web based display reports. • Display reports contain the display preview with markers that link a certain dynamic element with the according (telemetry) data source and command buttons command details. Uwe.Brauer@space.eads.net

  8. USS Executor • Designed for high usability and performance. • The USS Executor is tailored to the special needs of operations teams in control centres and test facilities. • Colours, fonts and indicators for monitoring and acquisition status are easily configurable for certain target specific target systems in by means of a global or a user defined configuration file. • Layout of a predefined set of displays can be saved and re-loaded later (e.g as a. set of displays for certain subsystem or activity). Display size and zoom settings are also restored. • Full status indication to the user: • Current mission time • Connection status to monitoring and control system • Overall monitoring status of single displays and for all open displays (see yellow indicators in image above) • Synoptics performance and update indication Uwe.Brauer@space.eads.net

  9. USS Executor: imported synoptics (ground textual displays, ISS onboard displays & procedural display) Uwe.Brauer@space.eads.net

  10. USS Executor: Commanding • Commanding capabilities benefit from the large experience for commanding critical systems in the onboard domain. • Different types of commands are supported single-step and two-step commanding, guarded commands and also parameterized commands. • The last four issued commands and their execution status are shown in the synoptic command response window Uwe.Brauer@space.eads.net

  11. On-the-fly graph and configuration data access • During synoptics execution it is possible to generate new graphs on-the-fly. • Show real-time and historical time series data with multiple plots. • Certain events can be selected for the graph to be shown as marker inside the graph. • Parameter properties window for showing the major parameter configuration data • It is planned to enhance this function with mission evaluation capabilities (e.g. support for time series analysis, save graph data for spreadsheet).

  13. Project Benefits (i.e. Columbus) • Reuse of the onboard displays on ground (Columbus related~400, totally for ISS ~6.000): ☺Displays must not be recoded and maintained/qualified only once ☺Onboard procedures can be reused on ground ☺Training material can be reused because flight controller and crew use the same displays • ISS Display standard (DGCS) compliance is much better than for the old systems ☺ Higher commonality with Nasa systems • Easy to use synoptics editor (MS Visio like) ☺ Reduction of synoptic preparation effort • Batch and interactive generation of display reports, consistency checks ☺Reduced verification effort • Full integration in ground and onboard consoles, harmonized user interface ☺ Reduction of training effort • Reduced overall software costs: ☺ Saving of runtime fees (for editor and executor) ☺ Saving maintenance effort Uwe.Brauer@space.eads.net

  14. Users • Columbus Mission Control Systems (System & Payload) • New Columbus onboard laptop system (LAPAP MKII) • Columbus Trainer: NASA PCS display simulator • NASA (PCS) displays Requirements Tool • Common Ground System (CGS) 6.x • Spin-off: Wind Power Facility Supervisor • ESA Study: MECA – Mission Execution Crew Assistant No. of Users: ~300 Uwe.Brauer@space.eads.net

  15. Development Roadmap • Current development contracts are ongoing until mid 2007 • Major software release and the monthly development snapshots will be made available via the public USS homepage: www.e-columbus.de/projects/uss Uwe.Brauer@space.eads.net

  16. Anticipated applications • USS team is searching for collaboration opportunities to apply USS technology for different application domains or additional spacecraft projects and facilities: • ESTEC EGSE Reference Facility (SCOS 2000) • Payload or subsystem EGSEs • Satellite EGSE and control centers • Future EADS “Low Cost EGSE” Supervisor • ESA studies or national projects • Future ESA / ESOC Ground Operation Software Systems • ESA technology studies • ESA exploration projects • Provide USS XML format as open standard for synoptic exchange between space projects Uwe.Brauer@space.eads.net

  17. USS Editor: Bitmaps (GIF, JPEG, PNG) Vector images (SVG) User defined symbol libraries (XML) USS synoptics (USS XML schema) Importers for commonly used synoptic formats System TM/TC configuration file (XML) Spell checking and operations nomenclature dictionaries (Tab Separated Values - TSV) Consistency check result (HTML) Manage synoptics in file system and Columbus Mission Database USS Executor Monitoring & acquisition status visualization style definition files (XML) Columbus data sources (CORBA) Columbus commanding interfaces (CORBA) User developed data sources and command handlers (Java) Graph history data (Comma Separated Values - CSV) Both: Display Report (HTML) Pluggable element types (Java plugin) User developed element types (Java) Interfaces Uwe.Brauer@space.eads.net

  18. Domain Modell Overview DataSources represent certain observables (measurement, TM, reporting data, Computations). Computations are expressions for: conditions, derived values, re-calibration, etc. During synoptic execution the chosen system specific DataProvider sends updates to the DataSource. The element is redrawn with according data updates (engineering & raw value, unit, monitoring & acquisition status, time, etc.) Uwe.Brauer@space.eads.net
