Towards  Forecasting Global Positioning System ( GPS ) Phase Scintillation Occurrence at  High Latitudes: Canadian High Arctic Scintillation Model (CHASM) — PI: Dr. Jayachandran  P. Thayyil. GNSS support a  wide range of civilian and military applications and have become indispensable  in precise positioning and timekeeping. As our society depends increasingly on  space technologies, and as our environment affects our daily life more than  ever before, solar-terrestrial interactions and their impact on the geo-space  environment have become increasingly relevant to Canada's economy and society.  Understanding these interactions will enable us to predict and forecast space  weather and subsequently mitigate detrimental effects on communication and  navigation technologies and other infrastructure. This project aims to develop a GNSS scintillation  forecasting capability for high latitudes and ultimately provide alerts and  warnings to clients and the general public, when and where GNSS availability or  position accuracy may be significantly compromised due to space weather events.
