Research Highlights

I. Equatorial Plasma Bubble detection and performance using multi-sensor mode

• Equatorial plasma bubble occurrence with VHF radar 
• 2-D TEC map generation over Thailand (and possibly ASEAN) and effects on improved positioning
• Artificial intelligence for Disturbance, Spread F and Total Electron Content 
• Analysis of ionospheric parameters (foF2, h’F, NmF2, etc.) and geomagnetic K-index: 
• Effects of earthquakes on Ionosphere

II. GNSS Positioning

• GNSS Position Error Map over Thailand
• RTK and PPP-RTK Technology improvement using observed iono delay in the equatorial region 
• Effects of Jamming and jamming detection to GNSS 

III. Augmentation Technology for Aviation in low-latitude region

• Ground-based augmentation system (GBAS):
  • Iono gradient analysis near Suvarnabhumi International airport
  • Effects of plasma bubbles on GBAS performance (CAT I, II, III) over Thailand
• Satellite-based augmentation system (SBAS): 
  • Performance of SBAS-I and DF-MC SBAS over Thailand region
