ConclusionsMitigation 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.
