This lecture delves into the analysis of extreme solar events and their impact on GPS positioning results, focusing on the Latvian CORS GPS observations during geomagnetic storms and sun flares. The study correlates space weather events with 90-second kinematic post-processing solutions, revealing outliers and errors in the positioning data. By examining over 36 million solutions, the study identifies erroneous results and errors exceeding 50 meters, shedding light on the vulnerability of GPS systems to extreme solar events.
