  1. TowardsInternational Cooperation and Capacity Building between Space Agencies: A Case of GISTDA and NSPO Pirada Techavijit ptechavi@eoc.gistda.or.th Ravit Sachasiri ravit@eoc.gistda.or.th GISTDA

  2. GISTDA (Geo-Informatics and Space Technology Development Agency) • Public Organization • Responsible for: • remote sensing • space technology • Operates Thailand Earth Observation System (THEOS -> Thai Chot) • first Thai earth observation satellite • Thai Chot was launched on 1st October 2008 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  3. National Space Organization (NSPO) • Taiwan’s civilian space agency • Established in October 1991 • Involved in the several areas including: • development of space exploration • satellite construction and development • research in aerospace engineering • remote sensing • Sciences such as Astrophysics, atmospheric science, information science and defense FORMOSAT-3 FORMOSAT-1 FORMOSAT-2 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  4. Cooperation Framework 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  5. Cooperation between GISTDA and NSPO • NSPO’s engineers visited GISTDA in 2010 • Observe current system • Agreement on requirements and setup of communication channel 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Cheingmai

  6. Remote System Management (Ground Sharing) • Increase system reliability • Co-operation with NSPO due to similarity of satellite system 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  7. Remote System and Anomaly Management • Setup of VPN connection between the two sites • Two parallel tunnels over different networks • The secure channel allow remote system management • Satellite anomaly and Ground system anomaly statistics and details are shared 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  8. Joint Programming • Increased shared value • Decrease time between acquisition • Better response to emergency situation 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  9. Joint Programming – Existing International Cooperation Disaster Response 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  10. Technical assistance/workshop • Both organizations share their core competences • Done both in person and remotely • Remote assistance and workshop includes: • E-learning • Online training • Remote Access over secured network to sensitive equipments • Exchange of information 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  11. Topics for Technical Workshop Training Course • Degradation trend and parameter adjustment for degraded equipment • Experience training operation on redundant equipment • Experience from bug fixing on Flight Software • Optimization of Attitude and Orbital maneuvers 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  12. Network Implementation Plan • Currently, all activities are done over the internet. • Current bandwidth available is approx. 5 Mbps BUT • All 3 of GISTDA’s site is connected to the UniNET • Which is part of TEIN 3 research network • NSPO is in discussion to connect to the TEIN3 network through the University in Taiwan • Possible Bandwidth – 20 Mbps 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  13. What would be possible? Loop Test Bangkok (UniNet) - Kuala Lumpur (Universiti Putra Malaysia) Uploading period to MY server • Tested files (THEOS images) was uploaded via internet connection • 3 Image files (199 MB, 189 MB, 748MB) = 1.5 GB • Using TEIN3 Route with UniNet server • Topology: ThaiREN Node – TEIN3 – Singapore Node • Bandwidth: 20 Mbps • Upload Time for 1.5 GB data: 4.52 min (748 MB data uses 2-3 min) 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  14. Existing usage of UniNET - THEOS Polar station Image Telemetry THEOS Raw Data Storage X-Band PolarStation (Kiruna) S-Band Station (SiRacha) X-Band Station (Bangkok) 20 Mbps Production Programming 155 Mbps Quick Delivery Central Archiving Catalogue Server 155 Mbps Media/FTP Service Ordering/Quotation Order Tracking Product Delivery Invoice/Billing Consultation DANTE: TEIN3/GEANT2 Request User International User (R&D/Universities) 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  15. Polar Station Data Transfer Acquisition in Sweden • Acquisition of Satellite data in Sweden • All Data are transferred for further processing in Thailand. • The polar station is connected with SUNET. • GISTDA’s station is connected with UniNet. • The data volume is around 690 MB to 30 GB image data per one orbits (~2 orbits/day) or upto 60 GB per day • Use of Data transfer over GEANT and TEIN3 greatly reduces transfer time in case of emergency situation Network Replay Production in Thailand 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  16. Network Topology: Overall SSC Network *Kiruna-Stockholm *Own Investment • New Implementation • Domestic • Own investment 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  17. Network status monitoring at UniNet Bandwidth used during data download from Kiruna > 30 Mbps 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  18. Conclusion • GISTDA is employing the research network to improve response to emergency situations • Remote maintenance and assistance greatly reduce the cost of maintenance • Plans to connect to NSPO through the Research network • Tests show that bandwidth available will be multiple fold over the current available system 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  19. THANK YOU 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Chiangmai

  20. Existing Connection from TEIN 3 33rdAsia-Pacific Advanced Network Meeting, 13-17 February 2012, Cheingmai

  21. Remote System management • GISTDA faces problem with S-band Antenna system • Slow recovery time due to foreign contractors • Reduced communication with THEOS • 28 Jun 2010 : GISTDA-NSPO Meeting at NSPO • 16 Sep 2010 : Cooperation Meeting between NSPO&GISTDA at SiRacha station Thailand on the Topic “Implementation of inter-operability between NSPO and GISTDA” • Both party agreed to implement the inter-operability of system.

  22. S-Band System Introduction The system consists on a 4.5 meter diameter antenna with S-band capabilities providing simultaneous transmission and reception capabilities for LEO satellites. The antenna provides satellite tracking by means of Program Tracking mechanisms.

  23. S-Band System Maintenance • Weekly maintenance • GMCs and CORTEX: Restart • Grease Pump • Oil Pump • Monthly maintenance • Antenna and Hexapod (Nut, bolt and cable) • Rack Maintenance: Visual inspection and remote function • LAN Hub • CORTEX and ADU: Visual inspection • Operation with GMC2 • Scan virus • GMC (G/T)

  24. S-Band System Maintenance • Yearly maintenance • Rack Maintenance: Visual inspection and local function • Switch Control Unit • Test Interface Unit: G/T (Signal test) and visual inspection • F&T Subsystem • COETEX: Cleaning • Down Converter • Up Converter • MCG • GMCs: Backup data • Servo Control Unit • Anemometer • Line Amplifier: Signal test • SSPA

  25. S-Band System Maintenance • Yearly maintenance (cont’d) • Antenna Drive Unit: Visual and power check • Dehydrator • Antenna and HXP: Cleaning and corrosion • Level Diagram • Change Oil and Grease

  26. S-Band System List of anomaly • Software • Monitoring and control program. Behavior: Error in this program caused malfunction of other equipments. Solution: 1. Request for support from software owner (updated patch, re-configuration, etc.). 2. Back up software. 3. Use as it. Cause: Bug in software.

  27. S-Band System List of anomaly • Software • Servo driving unit program. Behavior: Error in this program caused hexapod can’t be controlled. Solution: 1. Request for support either on-site support or remote support from Zodiac Cause:ESD in EEPROM of servo driving unit

  28. S-Band System List of anomaly • Hardware • HPA Behavior: 1. Inconstant output power. 2. No output available. 3. Lost communication with M&C program. 4. Completely break down 5. High temperature Solution 1. Repair by HPA owner. Cause: Short circuit in HPA. High electrical power drive to HPA

  29. S-Band System List of anomaly • Hardware • Hexapod Behavior: Cracking. Solution: Request on-site support from Zodiac Cause: Bolt brake broken

  30. Inter-Operability • Inter-operability present itself as a solution • Increase system reliability • Co-operation with NSPO due to similarity of satellite system
