6 New control strategies 6

7 New observation strategies for VLBI telescopes Wettzell, O Higgins/Antarctica and TIGO/Concepción Local - Standard operations - Local operator 7

8 New observation strategies for VLBI telescopes Wettzell, O Higgins/Antarctica and TIGO/Concepción Internet Local - Standard operations - Local operator Remote - Check system states from everywhere at the observatory - Tele-working - Remote assistance and diagnostics - Control very remote, inaccessible telescopes 8

9 New observation strategies for VLBI telescopes Wettzell, O Higgins/Antarctica and TIGO/Concepción Internet Internet Local - Standard operations - Local operator Remote - Check system states from everywhere at the observatory - Tele-working - Remote assistance and diagnostics - Control very remote, inaccessible telescopes Shared - Save, passive data live monitoring - Dedicated control access by responsible person - Shared access from different observatories - Shared night shifts 9

10 New observation strategies for VLBI telescopes Wettzell, O Higgins/Antarctica and TIGO/Concepción Internet Internet Local Remote Shared Unattended - Standard operations - Local operator - Check system states from everywhere at the observatory - Tele-working - Remote assistance and diagnostics - Control very remote, inaccessible telescopes - Save, passive data live monitoring - Dedicated control access by responsible person - Shared access from different observatories - Shared night shifts - Observations run autonomous, (semi-) automated and unattended 10

11 A possible basis for such strategies: e-control and SysMon 11

12 New observation strategies for VLBI telescopes Wettzell, O Higgins/Antarctica and TIGO/Concepción Internet Internet Local Remote Shared Unattended - Standard operations - Local operator - Check system states from everywhere at the observatory - Tele-working - Remote assistance and diagnostics - Control very remote, inaccessible telescopes 12 - Save, passive data live monitoring - Dedicated control access by responsible person - Shared access from different observatories - Shared night shifts econtrol* * per system with individual restrictions and only with reliable, well educated personnel staff on site - Observations run autonomous, (semi-) automated and unattended

14 The idea: remote attendance and control of VLBI telescopes Wettzell, O Higgins/Antarctica and TIGO/Concepción e-control FS Monitor Client GUI FS Monitor Client Communication Network FS Monitor Server Communication FS Monitor Server Functionality FS Monitor FS Graphical User Interface (GUI) Client Communication Server functionality Interface definition Device Device Device 14

15 The client graphical, textual or browser based Graphic and Classic main interface ogbook hat Remote program startup SSH Complete remote access 15

16 System Monitoring: SysMon Local safety for people and systems in combination with reliability in operations Meteo, WVR, Clock offsets, => low sampling rates => as scheduled Power supply, wind uploads, emergency stops, rack temp., => medium sampling rates => permanently Servo currents, contouring errors, => high sampling rates => on demand Data for science and analysis Data for system operations Data for diagnosis See also: Monitoring and Control Interface Collaboration Group 16

17 Optimization of workflows over system borders 17

18 VLBI The workflows on a technical point of view Schedule e-control/vlbi Session e-vlbi e-transfer (of scans) System Monitoring Storage e-transfer Shipment Quality Feedback 18

19 e.g. SLR The workflows on a technical point of view Predictions e-control/slr* * adapted from VLBI Ranging EUROLAS status System Monitoring Storage/ Screening FTP-Transfer Quality Feedback 19

20 Technical synergies in - Models - Software - Data - Observing Times - Manpower -... are the fundament for technical realizations of GGOS science Astronomic SKA science Picture: Download Picture: Download
