Abstract

Disruptions in GNSS signal integrity significantly and adversely affect positioning accuracy, especially in coastal navigation and restricted waters. Today, alongside modern bridge designs, the maritime industry has become highly dependent on Global Navigation Satellite Systems (GNSS) to ensure navigational safety. However, increasing incidents of signal jamming and spoofing, along with technical failures, expose the vulnerabilities of these systems and pose severe safety risks, particularly in coastal navigation and restricted waters. Furthermore, the reduced number of personnel on modern commercial vessels makes it difficult to effectively apply labor-intensive traditional navigation methods in emergency situations where GNSS data is lost. A review of the current literature reveals that studies on GNSS-independent alternative positioning systems predominantly focus on autonomous marine vehicles. Therefore, this study aims to analyze the need for a GNSS-independent positioning system that automates traditional bearing methods via optical sensors for non-autonomous vessels operating with reduced crews. The proposed system aims to determine the ship's position by automating the traditional visual bearing method using camera-based optical systems. Within the scope of the research, interviews were conducted with 15 ocean-going masters and maritime pilots. The findings revealed that 12 out of the 15 participants had previously encountered GNSS-related disruptions, confirming the critical need for an alternative system. Ultimately, this study envisions utilizing such technology as a decision-support tool to enhance the situational awareness of bridge officers.

Özet

GNSS sinyal bütünlüğünde meydana gelen kesintiler, özellikle kıyı seyri ve dar sularda konum belirleme doğruluğunu önemli ölçüde olumsuz etkilemektedir. Günümüzde modern köprüüstü tasarımları ile birlikte denizcilik sektörü seyir emniyetini sağlamak amacıyla Küresel Navigasyon Uydu Sistemlerine (Global Navigation Satellite Systems (GNSS)) son derece bağımlı hale gelmiştir. Ancak artan sinyal karıştırma (jamming) ve aldatma (spoofing) vakaları ile teknik hatalar, bu sistemlerin zafiyetlerini ortaya çıkarmakta ve özellikle kıyı seyri ile dar sularda ciddi emniyet riskleri oluşturmaktadır. Günümüzde ticari gemilerde azalan personel sayısı, GNSS verisinin kaybolduğu acil durumlarda insan gücüne dayalı geleneksel seyir yöntemlerinin etkin bir şekilde uygulanmasını zorlaştırmaktadır. Mevcut literatür incelendiğinde GNSS’ten bağımsız alternatif konumlandırma sistemleri üzerine yapılan çalışmaların ağırlıklı olarak otonom deniz araçlarına odaklandığı görülmektedir. Bu çalışma, otonom olmayan ve azaltılmış personel ile çalışan gemilerde GNSS'ten bağımsız, geleneksel kıyı seyri yöntemini optik sensörler yardımıyla otomatize eden bir konum belirleme sistemine olan ihtiyacı analiz etmeyi amaçlamaktadır. Önerilen sistem, geleneksel kıyı seyri yöntemini kamera tabanlı optik sistemlerle otomatize ederek gemi mevkiini belirlemeyi hedeflemektedir. Araştırma kapsamında 15 uzakyol kaptanı ve kılavuz kaptan ile görüşmeler gerçekleştirilmiştir. 15 katılımcıdan 12'si daha önce GNSS sorunlarıyla karşılaştığını belirtmiş ve alternatif bir sisteme ihtiyaç duyulduğu tespit edilmiştir. Çalışma teknolojinin köprüüstünde vardiya tutan zabitlerin durumsal farkındalığını artıracak bir araç olarak kullanılmasını öngörmektedir.
