  2. OUTLINE • Space weather • Space Weather Effect on GNSS • Space weather monitoring by using GNSS • Methodology • Status of GNSS Applications for Space Weather Monitoring • The Future Plan of Space weather monitoring using GNSS

  3. Earth weather and space weather

  4. SPACE WEATHER

  5. 2. Space Weather Effect on GNSS

  6. Ionospheric Delay (regular error) and Irreqularity (disturbance error)

  7. 3. Space weather monitoring by using GNSS

  8. 4. Methodology • Code and phase data extracting from GPS RINEX • GPS code data combination • GPS phase data combination • TEC Computation

  9. 5. Status GNSS Applications for space weather monitoring in Indonesia 1. Near real time IGS (GPS) based TEC monitoring 2. IPGSN-based TEC computation

  10. Near Real Time Ionospheric Monitoring Over Indonesia Using IGS GPS data Buldan, 2011, in progress

  11. Latest development of IPGSN-Based TEC Observations Buldan et.al., 2011

  12. Diagram Block of TEC computation System TEC calculator and data server (manual) Bako2300.11t (LAPTOP) GPS data extracter and combiner (automatic) bako2300P1P2.11c BAKOSURTANAL Real Time IPGSN Data Raw GPS format Internet LAN Data management (automatic) bako2320.11o bako232a.11o LAPAN

  13. TEC data

  14. Application of GPS TEC: GPS Phase Scintillation Index: Igps

  15. Igps phase scintillation index and FAI Buldan et. al., 2011

  16. Future Plans of Space Weather Monitoring using GNSS in Indonesi • GPS stations network in Indonesia • Plans of Space Weather monitoring

  17. GNSS observation network in Indonesia • Institutions have established GPS observation nework • LAPAN (3 station) • BPN ( CORS: 31) • BAKOSURTANAL (IPGSN : 70) • LIPI (SUGAR: 25 ) • ITB (CORS: itb1) • UGM (CORS: gmu1) • ITS (CORS: itss) 132 GPS receiver 18 GPS reciever: real time

  18. PLANS: DEVELOPMENT OF SPACE WEATHER MONITORING USING GNSS IN INDONESIA

  19. Needs: • Increase data storage capacity • Upgrade the data communication and networking insfrastructure • Humans resources development: acquisition, data processing and maintaining, networking and dissemination • Enhance the synergy among research and education institutions LAPAN-BIG-BPN-ITB-ITS-UGM

  20. Conclusions Mitigation of Space Weather Effect in Indonesia for GNSS application is requiring real time and continous GNSS stations Development of GNSS applications for space weather monitoring in Indonesia is ongoing research on space observation technology uisng GNSS Status of GNSS applications for space weather monitoring using GNSS are including ionospheric TEC and scintillation estimation from IPGSN, ionospheric mapping using IGS. Future plans of GNSS applications for space weather monitoring using GNSS are including the use of BPN CORS network and Univerities CORS network to provide the real time ionospheric conditions over Indoensia The GNSS applications for space weather monitoring are requiring the synergy among research and education institutions, human resources development, and insfrastructure development.
