Trimble product manager Keeley Shea joins us to dive deep into the atmospheric layers and solar storms and their impact on precise positioning. We explore the 11-year solar cycle, what happens during peak activity (like solar flares and geomagnetic storms), and how these phenomena, especially ionospheric scintillation, can cause issues with GNSS performance. We also cover how Trimble technology and best practices in the field can help mitigate these effects.
