2025 GNSS User Engagement

A GNSS User Engagement will be hosted by NOAA SWPC between 9 am and 12:30 pm on May 21st, 2025. Virtual or in-person participation is welcome. More details will be provided here. Please contact Tzu-Wei Fang (tzu-wei.fang@noaa.gov) if you have any questions. 

During the GNSS User Engagement session, the NOAA Space Weather Prediction Center (SWPC) will:

  • Provide information on space weather impacts on GNSS Positioning, Navigation, and Timing (PNT)

  • Present the latest ionospheric products and developments

  • Discuss strategies for integrating these products into GNSS solutions to mitigate space weather-related risks

This session will serve as a platform to exchange valuable insights and forge partnerships aimed at strengthening the entire PNT ecosystem against space weather challenges. Your expertise and leadership in the GNSS sector are invaluable, and we would be honored by your participation. We encourage you to join us in person if possible, and we would greatly appreciate a short (10-minute) presentation on:

  • Real-world scenarios in which space weather events have disrupted the accuracy, reliability, or continuity of GNSS-based systems

  • Future ionospheric products or enhancements that would be beneficial to your operations
