Abstract:
This Paper investigates geomagnetic polarity reversals and how they may affect ships safety of navigation as well as investigates the dangers that are posed with the geomagnetic disturbances.
This activity involves focusing on the impacts of particular disturbances on vital navigation systems like GNSS (Global Navigation Satellite System), ECDIS (Electronic Chart Display & Information System), and even the compass. The paper analyzes the impacts of such events on oceanic voyages as well as assesses the use of conventional techniques during these situations and developing appropriate contingency plans for the safe wet passage.
The methodology followed a mixed methods approach, which included a questionnaire, which was sent to foreign and Egyptian maritime professionals (shipmasters, navigators, and instructors); this was done in an attempt to gauge the industry awareness and preparedness. In addition, it is felt that the current levels of preparedness are inadequate for the potential alterations that may occur.
The study contributes novel insights into the specific technological vulnerabilities and operational challenges posed by geomagnetic reversals, offering actionable recommendations for improving navigational reliability for facing magnetic disturbances.
The primary results reveal major deficits in knowledge related to influences of geomagnetic polarity reversal on navigation systems as more than 60 % of respondents have a poor understanding. The results show that the world really need to plan for research on these issues. The findings highlight the urgent need for investment in targeted education and training programs, the development and implementation of robust alternative navigation systems, and enhanced international collaboration to build resilience within the maritime industry.
