Sažetak
Geomagnetic activity proved to be relevant indicator of the impact of space weather effects. The origin and development of solar events include various forms of manifestation in terms of energy and matter transfer to the near-Earth environment. These complex events may manifest as disturbances in the Earth’s magnetic field, further encompassing other types of disturbances, posing risks on various Earth’s technological and other systems. In the proposed paper, geomagnetic activity for the year 2012 has been elaborated, employing Kp geomagnetic index. Using the Kp dynamics pattern and considering possible geomagnetic impacts, assessment of potential risks on technology has been made. Satellite navigation system’s performance has been analyzed during events of increased geomagnetic activity through the year. The study showed that geomagnetic activity affected GNSS positioning performance in a measurable amount, preparing in this way the ground for further research.
